THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...OVERNIGHT.

...Potential exists for isolated strong storms near sunrise across 
the I-4 corridor and further southward during the day on 
Thursday...

.THUNDERSTORM IMPACT...
Model guidance continues to remain in agreement that a line of 
potentially strong storms may impact portions of east central 
Florida near sunrise Thursday morning. 

While the parameters that assess the potential for isolated strong 
storms are forecast to be highest across north and west-central 
Florida overnight, it appears as there will be modest instability, 
strong low and mid level winds, and sufficient wind shear values, 
for a line of thunderstorms over the Gulf of Mexico to maintain 
enough of its intensity as it travels eastward and reaches the I-4 
corridor near sunrise Thursday morning.

The greatest threat for gusty showers and thunderstorms is along and 
north of a line from Kissimmee to near Daytona Beach. Individual 
cells will move from out of the southwest at 45 to 55 mph due to the 
stronger winds aloft.

In addition to dangerous cloud to ground lightning strikes, a few of 
the storms will be capable of producing wind gusts between 40 and 50 
mph. Persons in east central Florida should stay informed of the 
weather expected very late tonight and continuing into the day on 
Thursday across east central Florida. Be prepared to move indoors to 
a place of safety well in advance of storms.

Stay tuned to NOAA weather radio, commercial television or radio 
stations, or your cable or satellite television provider for later 
statements concerning this potential.

.WIND AND SEA IMPACT...
Southeast to south winds 15 to 25 knots with frequent higher gusts 
will generate seas of 6 to 8 feet near shore and up to 10 feet 
offshore. A Small Craft Advisory is in effect for all of the waters 
of east central Florida into Thursday. However, a Gale Warning will 
go into effect late tonight for offshore marine legs as there will 
be frequent gusts to Gale Force.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY.
Poor to hazardous marine conditions are expected to continue
through late week as winds remain elevated ahead of and behind
a cold front that will move through the area on Thursday. The 
front will also bring a threat for isolated strong thunderstorms 
capable of producing cloud to ground lightning strikes and brief 
gusty winds. A Marginal Risk of severe thunderstorms is in effect
for portions of central Florida early Thursday.

.SPOTTER INFORMATION STATEMENT...
Spotter activation is not anticipated overnight, but a line of 
potentially strong lightning storms could approach the I-4 corridor 
from the west ahead of sunrise Thursday morning..
