...Strong Storms and Flooding Possible This Afternoon..
...Tropical Storm Conditions and Flooding Possible Tonight...

This hazardous weather outlook is for South Florida.

.DAY ONE...TONIGHT

Rip currents: A high risk for rip currents is forecast along all
Atlantic beaches.

Thunderstorms: Scattered to numerous storms are expected the rest of
today and into tonight. The primary threats will be locally strong
wind gusts, frequent lightning, and localized flooding.

Flooding: While isolated flooding will be possible with the heaviest
rain producing storms this afternoon, especially along coastal
Miami- Dade County, the bulk of the threat will hold off until
tonight when rain associated with Fred begins to move ashore along
the Atlantic coast.

Waterspouts: Waterspouts will be possible with showers and
thunderstorms across all local waters.

Wind: A few storms could become strong and may be capable of
producing wind gusts in excess 45 mph.

Tornadoes: Tornadoes are possible tonight as Tropical Depression Fred
approaches South FL.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY

Tropical Depression Fred, although disorganized this afternoon, is
expected to strengthen into a Tropical Storm tonight. Confidence is
relatively high in the general track and intensity forecast as Fred
moves through the Straits and across the Keys this weekend.

The main threat from Fred to the local area will be the potential
for localized flooding from excessive rainfall. A Flood Watch is in
effect from tonight through Sunday night.

Sustained tropical storm force winds are most likely over our Gulf
waters and the immediate southwest coast. Elsewhere, tropical storm
force winds will be most likely in occasional gusts.

A few tornadoes will be possible as Fred moves through the eastern
Gulf.

Poor marine and beach conditions are also expected, with a
heightened risk for rip currents and elevated surf along the Atlantic
coast (especially on Saturday).

.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.
