THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
An area of low pressure over extreme southwest Georgia early this
morning will continue move eastward and offshore today. The low
will swing a strong cold front across central Florida by tonight.
The front will be preceded by a fast moving band of showers and
possibly some embedded thunderstorms. While instability looks
somewhat limited, strong winds and forcing aloft will bring a risk
of a few strong storms.

The best chance for storms will occur over Lake county and the I 4
corridor between 9am and Noon, Brevard and Osceola counties
between 11 am and 2 pm, then reaching Okeechobee and the Treasure
Coast between 2 and 5 pm. The primary threat will be strong
straight line winds up to 50 mph with damaging winds around 60 mph
possible in a few storms. An isolated tornado cannot be ruled out
mainly north of a line from Kissimmee to Cape Canaveral.

.HIGH WIND IMPACT...
A Lake Wind Advisory is in effect for south to southwest winds 15
to 20 mph with frequent gusts near 30 mph. Gusts up to 35 mph will
be possible.

.RIP CURRENT IMPACT...
Weather and ocean conditions will produce a Moderate Risk of rip
currents at the beaches of east central Florida. The threat will
be greatest after Noon due to tidal effects. Always swim within
sight of a lifeguard.

.MARINE THUNDERSTORM GUST IMPACT...
Strong wind gusts of 35 to 45 knots may accompany embedded storms
as they push offshore the coast during the mid to late morning
north of the Cape and the early to mid afternoon south of the Cape.

.WIND AND SEA IMPACT...
A Small Craft Advisory is in effect for most of the local Atlantic
coastal waters for South to Southwest winds around 20 knots.
Occasional gusts to Gale force will be possible over the offshore
waters north of Sebastian Inlet and beyond 20 miles. Seas will
build 6 to 8 feet offshore and 4 to 6 feet nearshore.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY.
Boating conditions will remain poor to hazardous through Tuesday
night. Another strong cold front is forecast to cross the area
Friday or Friday night and bring another chance for heavy rain and
storms, some of which could be strong.

.SPOTTER INFORMATION STATEMENT...
Spotters are requested to monitor the weather and self activate
if needed.
