THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
Higher moisture will overspread the area today from the east and
produce a greater coverage of rain and storms. Scattered to
numerous showers and isolated storms will push onshore the coast
this morning and focus on the interior this afternoon. Instability
aloft may contribute to a few strong storms containing gusty
downburst winds up to 40 mph and frequent lightning strikes.
Due to moist soil conditions, even brief downbursts of heavy rain
may produce ponding of water.

.RIP CURRENT IMPACT...
A Moderate Risk of rip currents will exist at the beaches of east
central Florida. The threat will be highest during the afternoon
and early evening due to tidal effects. Always swim within sight
of a lifeguard and never swim alone.

.MARINE THUNDERSTORM GUST IMPACT...
A few storms may produce gusty winds near 34 knots over the
Atlantic and Intracoastal waters as well as inland lakes. Storm
motion will be generally toward the west or northwest at 10 to 15
mph.

.Waterspout Impact...
Deepening moisture, a weak wind profile, and inverted troughing
along the east Florida coast will promote waterspout development
with some shower and isolated storm activity this morning.

.WIND AND SEA IMPACT...
As Major Hurricane Maria lifts northward just east of the
Bahamas today and tonight, seas will build 7 to 8 feet this
afternoon and reach 9 feet tonight offshore the Volusia and
Brevard coasts. As a result, small craft should exercise caution
today offshore, north of Sebastian Inlet. Then a Small Craft
Advisory will go into effect there late this afternoon and
continue tonight.

.RIVER FLOOD IMPACT...
The Saint Johns River is forecast to remain in moderate flood
through the weekend near Cocoa, Sanford, Deland and Astor. The
Saint Johns River near Geneva is forecast to remain in major
flood.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY.
Although the eye of Major Hurricane Maria is forecast to remain
about 500 miles offshore the Florida Atlantic coast this weekend,
large swells are expected to affect the coastal waters and surf
zone beginning Saturday and continuing into early next week.
Conditions for small craft operation will become hazardous.

Beachgoers can expect a High Surf Advisory to be issued over the
weekend. The high surf expected from Maria will aggravate moderate
to severe erosion which has already occurred at some beaches. In
addition to large breaking waves, there will be a High Risk of rip
currents that will extend well into next week.

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

...High Risk of Rip Currents for Palm Beach County Beaches...
...Thunderstorms Possible Through the Evening hours...

This hazardous weather outlook is for South Florida.

.DAY ONE...TONIGHT

Rip currents: There is High Risk of rip currents along the beaches
of Palm Beach County, and a Moderate Risk of rip currents along the
beaches of Broward County.

Thunderstorms: Thunderstorms are possible this evening over South
Florida. The primary impacts will be lightning and heavy rainfall.


.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY

Scattered to numerous afternoon thunderstorms are possible over
South Florida on Saturday and Sunday, before drier air works into
the area late early next week reducing the coverage of the
thunderstorms.

Long period northeast swells from distant Post-Tropical Cyclone Jose
and Hurricane Maria will continue to lead to an enhancement of rip
currents along all Atlantic beaches through early next week.

Also, Atlantic coastal areas of South Florida may see high surf as
early as Sunday afternoon, which may also lead to some beach erosion,
especially in Palm Beach County.

Atlantic waters could become hazardous this weekend into early next
week due to the long period of northeast swells.

.SPOTTER INFORMATION STATEMENT...

Widespread spotter activation is not anticipated, however individual
spotters are encouraged to report waterspouts and other hazardous
weather to the National Weather Service forecast office in Miami.
