...SHOWERS AND STORMS ARRIVING LATE TONIGHT, A FEW STRONG...
...HAZARDOUS MARINE CONDITIONS CONTINUE...

This hazardous weather outlook is for South Florida.

.DAY ONE...TONIGHT

Rip currents: There is a high risk of rip currents for the Atlantic
beaches.

Thunderstorms: Thunderstorms are possible starting late tonight
across portions of South Florida and local waters as a cold front
approaches the region. The best chances for storms will be across the
local Gulf and Atlantic waters, as well as the adjacent coasts. A
few of thunderstorms over the Gulf waters into the Gulf coast, and far
western portions of Glades and Hendry counties will have the potential
to become strong to severe, especially towards daybreak. In addition
to frequent lightning strikes, strong to severe wind gusts will be
the main impact.

Waterspouts: A few waterspouts are possible across all South Florida
waters with any showers or thunderstorms beginning in the early
morning hours on Thursday.

Wind: Southeast to south winds of 20 to 25 knots will continue
across the local Atlantic waters, with wind around 20 knots across
the offshore Gulf waters. A Small Craft Advisory remains in effect.

A few thunderstorms late tonight could produce strong to severe wind
gusts across the Gulf coast, far western portions of Glades and
Hendry counties, as well as across the open Gulf and Atlantic
waters.

Waves: Seas of 6 to 7 feet are forecast for much of the Atlantic
waters and far offshore Gulf waters through the overnight hours. A
Small Craft Advisory remains in effect.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

The high risk for rip currents is forecast to continue through at
least Thursday for the Atlantic beaches.

Strong and gusty winds will continue to create hazardous boating
conditions across the Atlantic waters into Thursday.

Showers and thunderstorms are expected to be ongoing early Thursday
morning as a cold front moves through the region. The potential for
a few strong to severe storms will continue through early afternoon
before the front is expected to exit the area. The main impacts with
these storms will be frequent lightning strikes, with strong to
severe wind gusts also possible. Isolated tornadoes can not
be ruled out as the boundary moves through the area.

Another shot of cold air is expected to arrive behind the front
Thursday night, with low temperatures dropping into the 40s to
around 50 degrees across the interior and Gulf coast of Florida
each night through at least the weekend.

.SPOTTER INFORMATION STATEMENT...

Widespread spotter activation is not anticipated, however individual
spotters are encouraged to report high wind, hail and flooding to
the National Weather Service forecast office in Miami.

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..
