.DAY ONE...TONIGHT.

.THUNDERSTORM IMPACT...

east central Florida. The main impacts from storms will be
occasional lightning, brief gusty winds, and downpours.

over the Gulf Stream and move closer toward the coast toward
daybreak Thursday morning, while seas will be slower to build. A

daybreak Thursday morning areawide.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY.
A powerful storm system will develop and move east over the Gulf
Coast and southeast U.S. through Thursday. Ahead of the system,
increasing moisture and instability, strengthening winds and
favorable shear will bring the potential for strong to severe
thunderstorms Thursday, mainly during the afternoon and early
evening. Strong or damaging wind gusts, frequent lightning, and
local flooding from torrential rainfall are likely to accompany
these storms as they move rapidly east to northeast across the
peninsula. There is also the potential for a few tornadoes to
occur.

The storm system will drag a cold front across central Florida
Thursday night. Strong, gusty west winds are expected on Friday.
Increasing winds over the Atlantic will produce hazardous marine
conditions Thursday through Saturday, with winds near gale force
late Thursday through Friday night.

Residents and visitors should monitor the latest forecasts and
statements concerning this storm system, as well as the potential
for severe weather. Now is a good time to review your severe
weather action plan, and to make sure you have at least one or two
methods of receiving timely severe weather information, in case
