THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...THIS AFTERNOON AND TONIGHT.

.THUNDERSTORM IMPACT...
An isolated threat for lightning storms will be found south of
Indian River through southern Osceola counties. The main storm
threats will be occasional cloud to ground lightning strikes,
torrential downpours, and gusty winds.

.HIGH WIND IMPACT...
East-northeast winds will be 20 to 25 mph and gusty areawide today.
Gusts to near 40 mph may occur near the east coast this afternoon. A
Lake Wind Advisory is in effect for all of east central Florida.

.COASTAL FLOOD IMPACT...
Large breaking waves up to 5 to 7 feet within the surf zone will
likely produce minor beach erosion. This will be particularly true
around the times of local high tide from around 5 PM through 9 PM
tonight. A High Surf Advisory is in effect for the entire central
Florida Atlantic Coast.

.RIP CURRENT IMPACT...
A lingering long period ocean swell will lead to a moderate risk
for rip currents at area beaches today. The greatest threat will be
through 330 PM, due to tidal effects. Remember to always heed the
advice of local beach patrol before entering the water, and only
swim within sight of a lifeguard.

.WIND AND SEA IMPACT...
East-northeast winds up to around 25 knots with frequent higher
gusts will build seas to 7 to 10 feet near shore and up to 10 to 13
feet offshore. Frequent gusts to gale force are expected from
The Volusia-Brevard County line southward...and occasional gusts
to gale force will be possible to the north of this area.
A Gale Warning has been posted from the Volusia-Brevard County
line southward, and Small Craft Advisories remain in effect over
the Volusia County coastal waters.

.RIVER FLOOD IMPACT...
The Saint Johns river is forecast to remain in moderate flood
stage near Sanford, Deland and Astor. Near Geneva and Cocoa, where
the river is already in major flood stage, slight rises may occur
few days due to the recent heavy rains in Brevard County. Any
additional rainfall in the basin could enhance localized rises.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY.
A strong ridge of high pressure will produce several more days of
breezy to windy onshore flow. Gusty, onshore moving showers and
squalls are likely into at least Thursday, especially along the
coast. As seas and surf build through this week, conditions for
boaters and beachgoers will become increasingly dangerous.
Numerous strong rip currents are also likely, and additional
erosion of the already weakened beaches and the dune line may
occur around the times of high tides.

High rain chances will lead to localized flooding or aggravation
of ponding or standing water, especially in poor drainage and low
lying areas, water retention areas, and near larger river basins
such as the St Johns River, which is forecast to remain nearly
steady or slowly rise into the weekend.

.SPOTTER INFORMATION STATEMENT...
Spotter activation will not be needed today.
