EspañolTORNADOES OF 2007
This page documents the 'tornadoes and tornado outbreaks of 2007', primarily (but not entirely) in the United States. Most tornadoes form in the U.S., although some events may take place internationally, particularly in parts of neighboring southern Canada during the summer season. Some tornadoes also take place in Europe, e. g. in the United Kingdom or in Germany.
As of August 30, there have been 1,145 reported tornadoes in the U.S. (of which at least 475 have been confirmed), with 74 confirmed fatalities. It is already the deadliest year for tornadoes in the U.S. since 1999, when 95 deaths were reported.[1] In addition, three fatalities took place in Mexico, 14 in Chad, one in South Africa, three in Vietnam, one in the Philippines and 25 in China for a worldwide known total of 121.
Notably, the system for classifying tornado damage in the United States changed from the Fujita scale to the Enhanced Fujita Scale on February 1.[2]
Synopsis
The winter months of January and February are generally quiet in terms of tornado activity as the warm weather needed to produce such is generally confined to the tropics and subtropics, where cold fronts are infrequent to very rare. However, some outbreaks take place during those months, especially in the Gulf Coast region. The Southern Hemisphere would naturally be in a peak season then (being summer there), but apart from Australia, reported tornadoes are quite rare in the Southern Hemisphere. Activity quickly picks up in late February.
The peak season for tornado activity is from March to May in the Southern United States, while activity shifts northward to the Upper Midwest and Great Lakes regions in the summer months from June to August. A secondary peak occurs in October and especially November farther south. In addition, during hurricane season, many tropical storms and hurricanes produce tornadoes across the southern and eastern U.S.
However, there is no real "tornado season"; tornadoes, including violent ones, can happen at any time of year if the conditions are favorable.
Events
January
29 tornadoes were reported in the US in January, of which 21 were confirmed.
January 4-5
The first severe weather event of 2007 was a scattered but deadly tornado event in the U.S. Gulf Coast region on January 4. At least two people were killed in New Iberia, Louisiana. Several others were missing but later found, and at least 15 were injured, some critically. Many mobile homes were destroyed in the area. It was confirmed to have been an 'F1' as all the severe damage took place to mobile homes. At least four other tornadoes have been confirmed. One of them was an 'F2' tornado near Blackwater, Mississippi that injured nine people.[3] [4]
The activity continued farther east into Georgia and the Carolinas on January 5, with at least one, and likely more, possible tornadoes. At least 15 people were injured in a tornado in Liberty, South Carolina.[5]
January 7
More severe weather developed in the South on January 7. Several tornadoes were reported, with the worst damage taking place in the Lake Blalock area in Coweta County, Georgia. One house was destroyed and many others damaged. Fortunately, no one was injured by the 'F2' tornado.[6] Several other tornadoes were reported, including an 'F1' tornado confirmed in Barbour County, Alabama.[7]
January 13
Before the winter storm hit Texas on January 13, a tornado touched down in the central Texas town of San Marcos. It registered 'F1' by local weather and police authorities. No one was reported injured or killed, but moderate damage was sustained, including damage near the local police station and a light fixture manufacturing business. No other tornadoes were reported from the storm. The tornado was an estimated wide and three-tenths of a mile long. [8]
January 18
The cold front of severe winter storm "Kyrill" spawned several tornadoes in Germany, three of which were confirmed as of February 22. The first one caused severe damage in the city of Lutherstadt Wittenberg, Saxony-Anhalt. It hit at about 6:40 p.m. local time (5:40 p. m. UTC). Roofs were blown away and trees virtually torn apart. It is estimated to have been an F2 to F3 tornado. [9] [10] Two more tornadoes are confirmed from Brandenburg - one 'F3' tracked through Brachwitz and another 'F3' tornado took place in Lauchhammer in southern Brandenburg, which leveled massively built barns and snapped high tension poles. Several more possible tornadoes of that day in Germany are still under investigation.
February
89 tornadoes were reported in the US in February, of which 47 were confirmed.
February 1, 2007 also marked the changeover to the 'Enhanced Fujita Scale'.
February 1-2
In the early morning hours of February 2, three separate tornadoes ran across Central Florida. The most severe damage occurred in Lake County, where 21 people were killed. Two of the tornadoes were rated EF3 on the new Enhanced Fujita scale.
February 12-13
Beginning in the late evening hours of February 12 and overnight into February 13, at least 14 tornadoes touched down across southern Louisiana and Mississippi. The most significant were around Lafayette, Louisiana and in Greater New Orleans. Some of the tornadoes produced significant damage, including one in the Gentilly neighborhood of New Orleans, Louisiana which killed one woman and left dozens injured. [11]
More tornadoes developed across Alabama in the late afternoon of the 13th with several reports of damage across the state.
February 23-24
A moderate severe weather event took place on February 23 and 24 across the south-central United States. It was expected to have been much larger, on February 23, as a moderate risk of severe weather was issued by the SPC for both days over large areas.
The activity on February 23 was quite modest due to a late start and low dewpoints. Six tornadoes were reported (and two were confirmed), and no significant damage was reported. The area primarily affected was the southern High Plains.
At least 13 tornadoes were confirmed on February 24, with several of them being destructive. The strongest tornado was reported in Dumas, Arkansas, where many buildings have been destroyed or flattened, including an entire industrial park. At least 40 people were injured, but remarkably, no one was killed. Extensive looting was reported in the community after the tornado hit. The main employer in the town was also badly damaged by the 'EF3' tornado.[12] Several other tornadoes were recorded across Arkansas, Mississippi and Louisiana, with the strongest being 'EF2'.
March
216 tornadoes were reported in the US in March, of which 182 were confirmed.
February 28-March 2
A large storm system spawned a significant tornado outbreak, which began February 28 in Kansas and Missouri and continued March 1 in Alabama and Georgia. On February 28, a moderate risk was issued for both days, and on March 1 a high risk was issued for western Alabama, eastern Mississippi, the Florida Panhandle and southern and central Georgia. It was the first such issuance since April 7, 2006.
On February 28, 12 tornadoes were reported, eight in Kansas and four in Missouri. One of them destroyed a house in Linn County, Kansas and the tornado associated with this has been rated 'EF4'. Structural damage has also been reported near Adrian, Missouri, from a different, less powerful tornado.[13] Hail as large as baseballs were also reported.[14] Remarkably, no one was injured.
As of March 4, there have been at least 53 tornadoes reported that day. Significant damage has been reported near Caulfield, Missouri, and at least one person has been killed in a mobile home there.[15] In the early afternoon, supercells became widespread across the region.
A tornado in Enterprise, Alabama, heavily damaged a high school and several homes while killing as many as nine people when the roof of the school collapsed. One other person was killed in Alabama as well as nine in Georgia including six in a single tornado in Baker County[16] [17] A total of 34 tornadoes have been confirmed during the outbreak which killed at least 20. This outbreak was part of a large storm that produced a winter storm across the Midwest states, the Great Lakes, Quebec, Ontario, the Canadian Maritimes and the US Northeast killing an additional 19 people.
March 3
A tornado killed one and injured 350 in suburbs of Klerksdorp, South Africa. [18]
March 23-24
A severe weather event developed on the afternoon of March 23 across West Texas into the Texas Panhandle and particularly across eastern New Mexico. Several of the cells formed into tornadic supercells that evening, with at least 15 tornadoes reported and 11 tornadoes confirmed. A tornado rated 'EF2' hit Clovis, New Mexico, with as many as 12 injured reported, and a tornado rated 'EF1' hit Logan, New Mexico, where three people were injuries and many campers and mobile homes were destroyed.[19][20][21] In total, sixteen people were injured, and two people died after the tornadoes.[22]
Severe activity was not as widespread as expected on March 24. Four tornadoes were reported in northeastern Colorado, one of which was reported to be a multiple vortex tornado.[23]
March 28-31
A slow-moving system developed across the High Plains on the dry line on March 28. A 'moderate risk' of severe weather was issued by the SPC as widespread severe weather, including tornadoes, were expected throughout the afternoon and evening. In all, 65 tornadoes were reported in the region, with several destructive and large tornadoes taking place in numerous communities across the region.[24] Many other severe weather reports came in, including hail as large as softballs. Five people lost their lives.
The system gradually moved east on March 29, but the squall line leftover from events the previous night prevented a major outbreak. Even so, four tornadoes were reported in Oklahoma, two in the Oklahoma City metropolitan area, which injured several people.
The SPC had issued a 'moderate risk' again for March 30 and March 31 over portions of southern Texas. Few tornadoes were reported across the Midwest but one tornado hit midtown St. Louis causing damage to roofs, trees and signs including parts of a billboard sign that flew over and blocked Interstate 64. [25]
April
At least 157 tornadoes were reported in the US in April, of which at least 90 were later confirmed.
April 3-4
Another severe weather outbreak took place on April 3, exactly 33 years after the Super Outbreak. However, damaging hail and wind were the primary effects, although 10 tornadoes were reported in Texas, Tennessee, Kentucky, Arkansas and Alabama. Nearly 400 reports of hail were reported throughout the day with the majority occurring during the afternoon hours in Missouri, Illinois, Arkansas and Kentucky with also reports of golf ball to baseball size hail. The majority of the wind reports were from a bow echo that developed across central Kentucky and Tennessee during the evening hours and causing damage to trees, power lines, antennas and trailers. [26]. A total of 10 tornadoes were confirmed; all of them were 'EF0' or 'EF1'. No fatalities were reported, but several people were injured.[27] [28][29]
April 11
A severe weather outbreak occurred across the eastern central states on April 11, exactly 42 years after the deadly Palm Sunday Tornado Outbreak. The system spanned from Illinois and Indiana down to the southern states spawning seven tornadoes, 4 in Indiana (two 'EF0', one 'EF1' and one 'EF2' [30]) and 3 in Alabama (all rated 'EF1'[31]). The system also created damaging winds and a great amount of hail. [32]
April 13-15
On April 13th, severe weather developed across the Southern Plains, with the first storms affecting north-central Texas.
The Storm Prediction Center issued a 'moderate risk' of severe weather for April 13 (which is also Friday the 13th) over portions of North Central, Northeast Texas, Southern Arkansas and Northern Louisiana.[33] It was also issued for the central Gulf Coast for April 14. During the mid-afternoon hours, the moderate risk was upgraded to a 'high risk' for the second time in 2007.[34]
In the Dallas-Fort Worth Metroplex, there have been a couple of unconfirmed tornadoes throughout the region. Hail up to baseball and 'tea cup' (3.25 inch/8.5 cm) size and wind gusts to 80 mph (130 km/h) have been reported as well. [35] One fatality has been reported although it may have been either from the tornado in Haltom City or from straight-line winds according to WFAA coverage. The tornadoes were reported in Seymour, Texas and Haltom City, Texas where one (or two) deaths has occurred. Two tornadoes of one 'EF0' and an 'EF1' tornado were later confirmed in Tarrant County near Fort Worth while another 'EF0' was confirmed in Dallas County and a third 'EF0' in Rockwall County [36]. The severe weather caused cancellation of qualifying for the 2007 Samsung 500 at Texas Motor Speedway, forcing the field to be established via owner's points. Nonetheless, the overall activity was much lower than expected and the high risk busted.
For April 14th, the Storm Prediction Center issued a 'moderate risk' of severe weather for southern Louisiana, Mississippi, Alabama, Georgia and northwestern Florida. Several more scattered tornadoes were reported.
While most of the activity on April 15 was straight-line winds, an isolated 'EF3' tornado touched down in Sumter County, South Carolina that morning. Several mobile homes were demolished and one person was killed, with three injured. Two other tornadoes were later confirmed in South Carolina : an 'EF1' in Lee County and an 'EF0' in Orangeburg County. Several tornadoes also affected Georgia where at least 8 tornadoes and 3 injuries were documented. [37]
[38]
April 17
On April 17, although the SPC issued a slight risk of storms, a storm system progressed through Texas. The system spawned ten tornadoes through northern Texas, such as Anton, Lubbock and Haslet, which is only a few miles from where a number of tornadoes hit the Friday before, April 13, 2007. The system also created penny to ping-pong ball-sized hail and created dangerous wind speeds. Six tornadoes were confirmed, one 'EF1' and the others all 'EF0'. [39]
April 20-21
Activity was not widespread on April 20, but 8 tornadoes were reported in southwestern Nebraska, all from a single supercell that suddenly developed. Two have been confirmed as of April 23. A tornado near Moorefield, Nebraska has been rated 'EF3'. It destroyed six farmsteads and had a path length of 11 miles (17.7 km). [40][41] Another 'EF2' tornado was confirmed in Dawson County, Nebraska, which was over a mile (1.6 km) wide at its peak but fortunately remained in sparsely populated areas.[42]
On April 20, the SPC issued a moderate risk of severe thunderstorms for the Texas and Oklahoma Panhandles and the southwestern part of Kansas for April 21 which was extended into Nebraska later. Widespread severe weather developed that evening, although the primary result of the supercells was large hail. The meteorological synopsis was virtually identical to March 28 except for the fact that the air mass was not as unstable.[43] In total, 19 tornadoes were reported. [44] The hardest hit community was Tulia, Texas where many houses were reported to have been destroyed. That tornado was rated as a high-end 'EF2'.[45] Another strong tornado (also a high-end 'EF2') hit Cactus, Texas where significant structural damage was reported (including total destruction to at least 10 mobile homes) and 14 people were injured, but remarkably, no one was killed. The tornado was 3/4 mile (1.2 km) wide at its widest point.[46]
April 23-25
A severe weather outbreak was forecast for April 23 and 24 across the southern Plains. In the early morning hours of April 22, the SPC issued a 'moderate risk' of severe weather for South Central Kansas, Central Oklahoma, and North Central Texas. Such is an extremely rare issuance; only twice has such a risk been issued so far out - the others being for June 10, 2005[47] and January 2, 2006[48] (neither time did it result in a major outbreak). [49] It was also increased to moderate risk for April 23 as well. On the afternoon of April 24, the risk that day was upgraded to a 'high risk' over parts of East Texas.
Several tornadic storms were reported across northwest and south-central Texas, far western Oklahoma, and southwest Kansas. At least 29 tornadoes have been reported, and the National Weather Service has confirmed 3 in the DFW Metroplex, 1 in Hood county and 2 in Denton county. Some were reported to have been large and powerful in the sparsely populated area. However, no injuries were reported.[50]
The activity quickly redeveloped late in the morning of April 24. Tornadoes, along with large hail and damaging winds, occurred in the afternoon and evening hours across the Plains. 22 tornadoes were reported.[51] One large tornadic supercell also moved through Piedras Negras, Coahuila in Mexico, and moved into Eagle Pass, Texas, with reports of significant damage on the U.S. side of the border and at least seven deaths and 74 injuries from that 'EF3' tornado, plus at least three deaths and at least 40 injuries across the river in Piedras Negras.[52] There was virtually no activity in the high risk area, however, and that busted.
April 26
Several tornadoes developed across the Midwest and into the Tennessee Valley on the afternoon and evening of April 26. The hardest hit communities were LaPorte, Indiana (by two 'EF1' tornadoes[53])and New Tazewell, Tennessee (also by an 'EF1' tornado[54]) where structural damage was reported in both communities, and dozens of houses were damaged or destroyed. Several other scattered tornadoes were reported, along with widespread wind damage.[55] In total, seven people were injured. Four other tornadoes were confirmed in Ohio and Illinois.
May
At least 311 tornadoes were reported in the US in May, of which at least 110 were later confirmed. Confirmations are still ongoing, particularly from the May 4-6 outbreak.
May 1
On May 1, a tornado hit the village of Vershinino in the central region of Tomsk (Tomskaya Oblast') in central-southern Siberia. Some roofs were blown away and destroyed, windows were smashed and power lines as well as telephone lines were seriously demaged. An eyewitness reported that her child was whirled around as the tornado struck their street area.[56] Fortunately, no one was seriously injured or killed. According to a damage report, this tornado can be ranked as 'F2'.
May 2
On the afternoon of May 2, supercells developed across several parts of Texas. At least 10 tornadoes were reported, including two in the city of El Paso, however, the damage was relatively minor. Tornado watches were spread throughout Texas. However, the supercells redeveloped into a hybrid derecho across Central and North Texas that evening, stretching from the Dallas-Fort Worth Metroplex to south of Waco and extending eastward to about Longview. Widespread wind damage with winds in excess of 100 mph (160 km/h) have been reported.[57] In the Metroplex, more than 300,000 customers lost power as a result of the high winds. Some of the most severe damage included the loss of a roof at an apartment complex, extensive tree and power line damage (with many trees crashing into houses) and flipped tractor-trailers and mobile homes.[58] However, no fatalities have been reported.
May 4-6
Main articles: May 2007 Tornado Outbreak
A significant severe weather event developed across the central Plains on the evening of May 4. Early in the morning, The SPC issued a 'moderate risk' of severe storms for May 4 over portions of Central Nebraska, Western Kansas, Western Oklahoma, Eastern Colorado and portions of the Texas Panhandle.[59] Around 6:35 pm CDT (2335 UTC) on May 4, a tornado was reported by KWTV storm spotters on the ground near Arnett, Oklahoma. The tornado stayed in mostly sparsely-populated rural areas, but there were reports of a house 7 miles (11 km) west of Arnett being hit, with no word of any injuries. At around 9:50 pm CDT (0250 UTC), there was a violent and destructive tornado in southwest Kansas near Greensburg. The tornado also moved into other communities including Trousdale, Macksville, Ellinwood, Claflin and Holyrood which have taken direct hits from significant tornadoes.[60] City administrator Steve Hewitt has said that 90% of Greensburg was destroyed and at least 16 people were critically injured, according to Fox.[61] Much of Macksville has also been damaged or destroyed. At least 12 people died and at least 63 injured according to the National Weather Service and CNN. The tornado was rated an 'EF5' on the Enhanced Fujita Scale [62], the first since the new scale was implemented and the first category 5 tornado since the Bridge Creek tornado during the Oklahoma Tornado Outbreak on May 3, 1999.[63] Another person was killed when a tornado destroyed structures in Ottawa County, Kansas, and another died in Stafford County, Kansas for an outbreak total of 14.[64]
On the morning of May 5, the SPC issued a 'high risk' across central Kansas and Nebraska. The SPC also issued a 'moderate risk' for southern South Dakota and northwest Oklahoma and a 'slight risk' for most of Oklahoma, northern South Dakota, southern North Dakota, eastern Nebraska, western Iowa and northeastern Colorado. [65]
There were 149 tornadoes reported across the area during the outbreak, including 7 on May 3 in Colorado and 30 on May 4. Three other tornadoes were reported in Illinois from a different system. 102 tornadoes were reported on May 5, across the same areas except Illinois. Some of the reports from May 5 are probably duplicate reports.[66] Ten tornadoes were reported across Kansas, Oklahoma, and Texas on May 6. A tornado that was reported in Florida was separate from the system in the plains and was not included in the count.[67]
May 6 (Europe)
Also on May 6, a tornado hit the village of Borod in Bihor region in western Romania, 40 km east of Oradea. The tornado moved a truck, damaged roofs and snapped trees. This event was ranked as 'F1'.
May 9 (Northern Ireland)
A tornado struck Carrickfergus, Northern Ireland (United Kingdom) resulting in roof damage and vehicle damage. There was 1 injury in the second tornado in 5 months to strike eastern Northern Ireland.[68] The tornado of Carrickfergus was ranked as 'T2/F1' event.
May 9 (Chad)
Also on May 9, a strong tornado struck Bebejia, Chad destroying the town and killing 14 people.[69]
May 11
During the late afternoon hours two tornadoes struck eastern Poland. One of them hit the small villages of Chodorówka Stara and Kopciówka near Suchowola in Podlaskie (north-eastern Poland). The 'F1' tornado caused serious damage to roofs of houses and barns.
The second tornado struck the village of Opole Lubelskie in Lubelskie (eastern Poland), destroying a circus tent. Up to 40 people were injured, most of them were children, who watched a circus show as the tornado struck the area.
Also on May 11, a tornado hit the areas of Dunboyne and Ashbourne in Meath (eastern Ireland) and caused light damage to roofs in this area.
May 15
Around 5:30 PM on May 15, a cluster of strong thunderstorms rolled through Southeast Michigan and Southwestern Ontario, causing one tornado touchdown near Bad Axe, Michigan, tracking towards Lake Huron before dissipating. This tornado was detected by radar from numerous and -area television stations' radar systems as upper-level cyclonic rotation. After crossing Lake Huron, the same system once again intensified and a strong 'F1' tornado touched down in a rural area north of Mitchell, Ontario causing some damage [70] There was also an 'EF0' tornado in northern Indiana as well as in southern Ohio.
May 21-23
On May 21, 4 tornadoes were reported in North Dakota and Nebraska. None of them have been confirmed yet. [71]
On May 22, the SPC issued a slight risk of severe weather for portions of South Dakota, Nebraska and Kansas. [72] Environment Canada also issued a slight risk of severe weather for northwestern Ontario near the Minnesota border. [70] 8 tornadoes have been reported in northwestern Kansas.[74]
On the afternoon of May 22, the SPC issued a 'moderate risk' of severe storms for parts of western Oklahoma, southern Kansas, and the northern Texas Panhandle for May 23. Significant (EF2-EF5) tornadoes were possible inside the moderate risk area.[33] On May 23, at least 10 tornadoes were reported along with large hail as big as softballs.[76] NWS Amarillo has suggested that 12 tornadoes may have been confirmed in their jurisdiction, but no EF-scale ratings have been released as of yet.[77]
June
150 tornadoes were reported in the US in June, of which at least 45 were confirmed.
June 1
A sudden string of supercells developed across eastern Iowa early in the afternoon of June 1 and tracked into northwestern Illinois and southwestern Wisconsin. While there were 15 initial tornado reports, most were duplicates and only three were confirmed. The hardest hit communities are Muscatine, Iowa where widespread structural damage has been reported including businesses destroyed and many injuries may have occurred, and Grandview, Iowa which has been sealed off due to the extensive damage. Houses have been reportedly "flattened" in Grandview and people have been reported to have been trapped by that 'EF3' tornado.[78][79] A second nearby tornado, rated 'EF2', also left significant damage around Bellevue, Iowa.[80] No fatalities were reported.[81]
June 6-8
An low pressure system moved across much of central and eastern North America starting on June 6 in the central Plains and into the Mississippi Valley, Great Lakes region and eventually the Northeast over the following few days. On June 4, the SPC issued a 'moderate risk' of severe weather for June 6, only the fourth such issuance for a day three outlook. On the morning of June 5, the SPC continued the moderate risk for June 6 and issued a 'moderate risk' for June 7 over much of the Upper Midwest, making it the fifth time a moderate risk has been issued on day 3. Both were forwarded to days 1 and 2, respectively, on June 6.[33][49]
On June 6, there were two distinct threats forecast The central Plains were expected to potentially see a large tornado outbreak, particularly in Nebraska and the Dakotas close to the dry line, should the cap have broken in the atmosphere in the afternoon hours. In the evening and overnight hours, a major derecho with destructive winds and some scattered tornadoes was possible farther east, particularly in the eastern Dakotas, western Minnesota and western Iowa.[72] However, that basically busted as not much severe weather happened as the cap held up in most areas. Only five tornadoes and scattered wind reports took place.[85]
A 'high risk' of severe storms has been issued for June 7 for the Upper Midwest, from about the Quad Cities north to Lake Superior. Widespread tornadoes and destructive downburst winds are again possible.[72]. A moderate risk has been issued for portions of Minnesota, Michigan and Illinois while slight risk was issued south towards Oklahoma, which has since been upgraded to a moderate risk. Environment Canada also issued a risk of severe thunderstorms with possible tornadoes for all of northwestern Ontario and a severe weather watch was issued early Thursday morning from the Manitoba border towards the north shore of Lake Superior [87] [88]
There were 14 tornado reports that day. The most serious damage was near Mosinee, Wisconsin where a house was heavily damaged by an 'EF2' tornado, and in Wisconsin Rapids, Wisconsin where a weak tornado touched down in or near the downtown area, along with softball sized hail.[89] However, farther south, the cap has held in place once again, restricting activity to the northern areas.[90]
The largest confirmed tornado on June 7 was an 'EF3' that touched down in central Wisconsin. It was on the ground for 40 miles (64 km) while passing through Shawano, Menominee, Langlade, and Oconto counties. It was up to 1,300 yards (1.2 km) wide at times and took down 14,000 acres (57 km²) of forest, damaging dozens of buildings.[89]
On June 8, Environment Canada issued a moderate risk of severe thunderstorms for Eastern Ontario with the risk of tornadoes. Slight risks were issued for most of Southern and Northeastern Ontario. The slight risk zone extends from southern Quebec, near Montreal into northern Mexico [72] [70] During the noon hours, the moderate risk zone was extended further south to includes portions of western New York, western Pennsylvania, northern West Virginia, northern Kentucky, southeastern Indiana, most of Ohio and larger portions of southern Ontario from Windsor to eastern Ontario. It turned out to be a long squall line though, and while there was wind damage from winds as strong as 85 mph (135 km/h) stretching from the Tennessee Valley north to almost Hudson Bay, there were only 2 possible tornadoes, one near Brantford southwest of Toronto and the other near Bancroft north of Peterborough, Ontario, but none were confirmed as of yet. [70] [95]
No fatalities have been reported from the entire severe weather outbreak.
June 7 (Vietnam)
A strong, apparently long-track tornado damaged dozens of buildings in multiple villages in Hung Ha district, Thai Binh province, northern Vietnam, killing one.[1]
June 13
On June 13, a "strong" tornado struck the Trieu Son district in Thanh Hoa province of central Vietnam, killing two whilst heavily damaging nearly 500 houses.[2]
An Ef-1 tonado briefly touched down in Allegany County, Maryland near the town of Flinestone. Numerous trees knocked down or uprooted
June 15
A series of severe storms brought heavy flooding to the Midlands and Yorkshire, along with at least 9 tornadoes across England, possibly including a very wide wedge tornado in Cornwall.
June 19
A supercell that developed over the Nebraska/Kansas border produced extensive hail and at least 7 reported tornadoes. The storm that travelled southeast through Oklahoma and North Texas eventually became an Mesoscale Convective Complex dumping heavy rain across areas that had been hit with significant flooding.
A sharp cold front also produced widespread wind damage across the Great Lakes and the Northeast and at least one reported tornado. [96]
June 21-23
A 'moderate risk' of severe thunderstorms was issued by the Storm Prediction Center for portions of eastern Iowa during the late afternoon of June 21. 7 tornadoes were reported across the Plains as a large cluster of storms was moving slowly eastward. Several reports of large hail exceeding golf ball size was also reported. [72] [98] The strongest tornado took place in Norwalk, Iowa, it was an 'EF2' which heavily damaged several houses.[99]
On June 22, more severe storms developed, this time primarily farther north. The most intense weather was across southern Manitoba where several tornadoes have been reported. The most severe damage was around Elie, Manitoba where several houses were flattened and numerous others damaged or destroyed. A flour mill was also destroyed and several trucks were overturned on Highway 1. The tornado path was about 6 km (3.7 miles) long and 300 m (330 yd) wide. It has been initially rated as an 'F4' on the Fujita Scale, the first violent tornado in Canada since one in Edmonton in 1987. (The EF scale has not yet been adopted in Canada.) Remarkably, no injuries were reported.[100] Another tornado hit McHenry County, North Dakota; it was an 'EF1' with moderate damage, mainly to trees and farm buildings.[101]
More tornadoes were possible across southeastern Saskatchewan, southern Manitoba and extreme northern North Dakota on June 23. The cap broke across the northern parts of the area and supercells formed that afternoon, primarily in Manitoba. At least five tornadoes were reported, including large wedge tornadoes. Fortunately, they missed populated areas for the most part. One of the tornadoes traveled 15 km (9 miles) south of Baldur, Manitoba and was rated an 'F3' on the Fujita scale. [102] [103]. The tornadoes were described as being "as bad as they ever get here in Canada" (referring to the F4 tornado) as meteorologist Dave Carlsen of Environment Canada told Canwest Global affiliate CKND-TV [104]
June 26
A single tornado hit Ignace, Ontario in the north-west part of the province overturning boats, causing damage to trees and property as well as injuring one person.[105]
July
There were been 55 tornadoes reported in the US, of which at least 19 have been confirmed.
July 3 (China)
A tornado in Eastern China had killed 14 and injured over 100. Three villages in the province of Anhui were particularly hard hit by the storm. [106]
July 3 (US)
A tornado outbreak affected small portions of Colorado, mostly over Kit Carson County, where 10 tornadoes were confirmed including 9 EF0's and 1 EF1. 7 of the tornadoes occurred within of Seibert. [107]
July 4-5
An outbreak of tornadoes occurred across New Zealand's North Island. Six were reported in the city of New Plymouth, Taranaki, devastating many houses and part of the Central Business District. Whakatane, Tauranga and Auckland were also effected by tornadoes.[108][109]
July 8
A tornado near Mildmay, Ontario confirmed as an F1, destroys a large implementation shed. Debris reported 1.5 km away, 50 kg drums moved. Another tornado is sighted in the area but unconfirmed touchdown.[110]

August 8
:''Main article: 2007 Brooklyn tornado''
An unusual 'EF2' tornado struck New York City at 6:30 am EDT (1030 UTC) on August 8. The hardest-hit areawas the Bay Ridge area of Brooklyn, where many trees—as much as 40% of the trees in Sunset Park were knocked down and several homes and buildings lost part of their roofs. A second tornado was also confirmed just east of the track of the first tornado and rated as a strong 'EF1' where additional roofs of homes were damaged. The Flatbush neighborhood, as well as areas on Staten Island, were also affected.[112][113]
Accompanying the tornadoes was a storm which dumped several inches of rain on the city in a few hours, resulting in flooding which effectively shut down the mass transit system. Several people were injured by the tornado, and one person died from the associated flooding. The tornado was the first to hit Brooklyn since 1950 when modern record-keeping began.[114]
August 9
At the northern boundary of a heat wave, severe thunderstorms developed on the afternoon of August 9 in Ohio and western Pennsylvania. Several sudden supercells developed with at least four tornadoes reported, primarily around Akron, Ohio. Significant damage was reported, including roofs removed from a high school and a factory, as well as numerous houses. Widespread straight-line wind damage was also reported. One person was killed by a fallen tree limb in Marion, Ohio, although it is unclear if it is due to a tornado or straight-line winds.[115]
In Pittsburgh, a funnel cloud was spotted downtown near the Carnegie Science Center, shattering windows and evacuating the 1000 patrons to the lower level. The museum was closed until August 13. Over 90,000 homes and businesses were without power, some not receiving it until August 12.
[116]
August 10
One person was killed when a tornado had struck Zambales, Philippines. Several homes were also heavily damaged or destroyed. [117]
August 19 (Typhoon Sepat)
A tornado spawned by Typhoon Sepat touched down in Zhejiang Province. It destroyed many buildings in the region. 11 people were killed by the tornado and 60 more were injured.[118]
August 23-24 (US)
A tornado was spotted in Sanilac County, Michigan around 5:21 PM EDT on August 23, after a hot muggy day caused convection east of an oncoming (eastbound) cold front. Another unconfirmed tornado was spotted tracking from Livonia, Michigan to Redford Township, Michigan.
It was part of a larger derecho with winds up to 100 mph (160 km/h) that did significant damage in the Chicago area and in western Michigan. Embedded in the derecho was an 'EF1' tornado that touched down in Winfield, Illinois in DuPage County.[119]
The National Weather Service office in Grand Rapids, Michigan, confirmed that two 'EF1' tornados hit rural Montcalm County near Cedar Lake.[120] Non-tornadic severe thunderstorms also did serious damage in Berrien, Van Buren, Kalamazoo, and Allegan counties. One man was killed in southwestern Kalamazoo County, and over 41,000 residents were left without power in the city of Kalamazoo alone.
On August 24, following conditions similar to the previous day, an 'EF3' tornado with "winds near " formed two miles (3 km) north of Charlotte, Michigan, doing severe damage along Vermontville Highway, passing through Potterville, and crossing I-69 in Eaton County before dissipating as it approached Dimondale, touching down around 4:25 PM EDT and leaving a damage path varying from to wide and long.[121][122]
Around 4:55 PM EDT, the same storm produced an 'EF1' tornado which touched down at the intersection of Waverly Road and M-99 in southeastern Lansing, extending across I-96, towards the intersections of Aurelius Road with Jolly Road and Dunkel Road before finally dissipating near the Jolly Road interchange on I-496.121122
Other storms in the same system later produced tornadoes in the NWS Detroit/Pontiac office coverage area. The most powerful one was a "strong 'EF2'" that touched down in Cohoctah Township, Livingston County, Michigan at around 5:30 PM EDT. Remaining on the ground for 26 miles, with an average track width of and a maximum track width of one-quarter mile in the city of Fenton, Genesee County, the funnel continued through Deerfield Township and northwestern Tyrone Township before entering Genesee County and the city of Fenton, where it caused the partial collapse of "a large retail structure" at the intersection of Owen Road and US-23. It then passed on into Holly, in Oakland County before dissipating into straight-line winds east of Holly.[123]122
Three other tornadoes were confirmed by damage surveys. An 'EF0' tornado touched down briefly (track length 50 yards) near the intersection of Durand Road and M-21 in eastern Shiawassee County, Michigan at around 5:23 PM EDT, while another 'EF0' tornado touched down for three miles (5 km) in Salem Township, Washtenaw County at around 6:02 PM EDT. Additionally, an 'EF1' tornado struck in Hadley Township, Lapeer County, at around 6:16 PM EDT, leaving a four mile (6 km) long damage path.123122 Numerous reports of straight-line wind damage were also received throughout the entire NWS Detroit/Pontiac coverage area.
The storms in this system were part of the same system that sat over the Midwest Areas for almost a week, bringing pouring rain at first then the Severe Weather later in the week. This storm system and stationary front is also blamed for the flooding in the Ohio area.
August 23 (Colombia)
A rare tornado occurred in the capital of Colombia, Bogotá, and was caught on tape. There were no immediate word on any damage or injuries. [124] Much of western Colombia lies along the Andes mountain chain which limits tornado activity in that region. However, in June 2001 a tornado killed six people and injured 350 in the town of Barranquillia in extreme northern Colombia. [125]
August 26
An isolated tornado event produced at least four tornadoes in eastern North Dakota and northwestern Minnesota on the evening of August 26, 2007.[126] One of the tornadoes was very destructive and did widespread damage in Northwood, North Dakota. One fatality occurred in Northwood and multiple structures were damaged or destroyed including a mobile home park and the community's hospital, school, and fire hall. This was the first killer U.S. tornado since May 5, 2007.[127][128] 18 other people were injured by the tornado, which was about 0.8 mile (1.3 km) wide. Surveys confirmed it to be an 'EF4' tornado; the fifth violent US tornado of 2007.[129]
