* STORM CLASSIFICATION: AT LEAST EF-3 INTENSITY TORNADO
* MAXIMUM WIDTH: 250 YARDS
* FATALITIES: 1
* NOTES: DUE TO THE EXTENSIVE DAMAGE IN THE LEAKESVILLE AREA, THE SURVEY TEAM WAS NOT ABLE TO ASSESS THE ENTIRE TRACK OF THE TORNADO. ADDITIONAL SURVEYS WILL BE NEEDED TO FINALIZE BOTH THE INTENSITY AND THE PATH LENGTH.

COUNTY)
* STORM CLASSIFICATION: EF-3 INTENSITY TORNADO
* MAXIMUM WIDTH: 200 YARDS
* FATALITIES: 3
