THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
Low pressure centered over the northeast Gulf of Mexico this
morning will track southeast across the south Florida peninsula.
This will bring widespread showers to east central Florida,
especially after midday. Isolated thunderstorms will also be
possible, mainly this afternoon and into this evening. Main
threats will be dangerous cloud to ground lightning, gusty winds
up to 40 mph, small hail, and torrential downpours, as storms move
toward the north to northwest up to 20 to 25 mph.

.FLOOD IMPACT...
Persistent bands of moderate to heavy rainfall may develop along
coastal areas of east central Florida, producing locally heavy
rainfall up to 2 to 3 inches. This may produce ponding of water on
area roadways and low lying areas.

.MARINE THUNDERSTORM GUST IMPACT...
Showers will become widespread across the local Atlantic waters by
this afternoon, along with a few thunderstorms. Any storms that
do develop will move toward the north to northwest. Any of these
storms will be capable of generating wind gusts in excess of 34
knots as well as dangerous lightning.

.WIND AND SEA IMPACT...
Marine conditions will be poor over the local Atlantic waters as
an approaching storm system allows south to southeast winds to
increase to 15 to 20 knots nearshore and 20 to 25 knots offshore.
Seas will build up to 4 to 6 feet nearshore and 5 to 7 feet
offshore as the winds increase. A Small Craft Advisory is now in
effect for all of the coastal waters of east central Florida.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY.
As the storm system pushes slowly into the open Atlantic, winds
will back to the northeast from Sebastian Inlet northward,
increasing to 25 to 30 knots with gusts to gale force. This will
generate dangerous marine conditions over the local Atlantic
waters, with seas building to 8 to 12 feet north of Sebastian
Inlet, and 5 to 7 feet to the south. Isolated thunderstorms may
linger into Thursday as well, as well as the potential for locally
heavy rainfall, mainly along the coast of Brevard and Volusia
Counties.

.SPOTTER INFORMATION STATEMENT...
Spotters are requested to report any locally heavy rainfall
amounts greater than 2 inches.
