...Moderate Risk Of Rip Currents Beaches Of Palm Beach County...
...A Few Strong Storms Possible Friday Into Friday Evening...
...Hazardous Marine Conditions Developing This Weekend...

This hazardous weather outlook is for South Florida.

.DAY ONE...TODAY AND TONIGHT

Rip currents: There is a moderate risk of rip currents along the Palm
Beaches. Swim only at guarded beaches and heed the advice of the
beach patrols.

Thunderstorms: Scattered thunderstorms are possible mainly across
mainland South Florida today with a chance of scattered to locally
numerous thunderstorms approaching the region from the Gulf of
Mexico waters overnight as a cold approaches south Florida. Main
concerns with this activity would be occasionally lightning strikes
and brief periods of heavy rainfall.

Waterspouts: A few waterspouts are possible across the South Florida
Coastal waters. .

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

A cold front is forecast to move across the region late Friday Night
through Saturday. A few strong storms are possible ahead of the front
Friday and Friday evening.

The risk of rip currents is forecast to remain moderate rest of the week
for the Palm Beaches and to become high behind the front this
weekend for all of the Atlantic beaches. There will be a moderate
risk of rip currents for the Collier county beaches early in the
weekend.

Hazardous marine conditions for small craft are forecast to develop
this weekend across portions of the South Florida waters behind the front.
The greatest concern is for the Atlantic gulf stream waters and the
offshore Collier county waters.

Coastal Flooding will be possible along the Atlantic, especially
during high tide Friday and Saturday. Due to continued northeasterly
swell along with King Tides, some minor coastal flooding will be
possible.

.SPOTTER INFORMATION STATEMENT...

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.
