Eustis Florida Tornado - September 20, 2007

Title:
Eustis Florida Tornado - September 20, 2007

Description:
A Complete Radar Survey of the Eustis event. Radar Stations used: KMLB Melbourne, Florida KTBW Ruskin, Florida KJAX Jacksonville, Florida KVAX Moody Air Force Base, Georgia Eustis is located dead center of the radar screens. A stacked mid to upper level low across the Eastern Gulf of Mexico induced an area of surface low pressure to develop on Thursday, September 20th. During the late afternoon into the early evening hours the low level southeasterly flow strengthened as the east coast sea breeze moved into far interior sections and the surface low pressure that would become Tropical Depression #10 continued to slowly organize. Mid to upper layer south to south southwest flow along with low level southeasterly flow allowed deep moisture to surge northward. The directional shear and low level helicity increased by late evening and deep convection developed along quasi-stationary boundaries across western Orange and Lake counties. After sunset, lowering LCLs and storms forming in a conducive environment for low level rotation allowed a long tracked super cell to develop near Lake Apopka and track northward toward Mount Dora, and finally Eustis where the tornado touched down at about 11 PM, along approximately a two mile path length before the storm eventually crossed into Marion county. The NWS Survey judged the tornado to have reach the EF-1 level on the Enhanced Fujita Scale of Tornado Intensity, with maximum winds of 100 - 105 MPH.
