Severe Thunderstorm Threat:

A Tornado Watch will be in effect into

the early evening for the Big Bend

counties, east of Tallahassee. Primary

threat will be from isolated damaging

winds and possibly a tornado. A

waterspout was reported earlier just off 

Franklin County which crossed the bridge

to St. George Island with a severe stormearlier this afternoon.

There will be a lull between the ongoing

storms moving across the eastern half of 

the area this afternoon and the next round

which should arrive as a broken squall

line later tonight.

Tornado and damaging wind risk will be

greater with the broken squall line tonightinto tomorrow morning. Most areas can

expect 40-50 mph winds with higher gusts

with the line. Obviously the stronger

storms will be capable of much stronger

winds. Tornado risk will also be a factor

tonight. We can expect a tornado watch

to be issued at some point overnight, if 

current forecast trends continue. The

severe threat will likely be greatest acrossnorthern FL and far southern GA where

the instability will be higher.
