...Moderate Risk of Rip Current Atlantic Beaches...
...Thunderstorms Possible Across South Florida Today...

This hazardous weather outlook is for South Florida.

.DAY ONE...TODAY AND TONIGHT

Rip currents: There is a moderate risk of rip currents along Atlantic
beaches.

Thunderstorms: A few thunderstorms will be possible over the
Atlantic waters and east coast this morning, becoming scattered
across the interior and Gulf coast this afternoon and evening. The
main threats with any storms will be cloud to ground lightning and
locally heavy rainfall.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

A tropical disturbance is forecast to lift slowly northward into the
Gulf of Mexico late this week into the weekend, bringing another
surge of deep tropical moisture to South Florida. Regardless of any
development, numerous to widespread showers and thunderstorms are
expected to return to the forecast for the end of the week,
continuing through the Memorial Day weekend. Heavy rainfall will be
possible during this time, aggravating ongoing flooding concerns. In
addition, gusty winds and locally rough seas, and occasional
lightning will accompany this activity.

The risk of rip currents will remain elevated for the Atlantic
beaches through the Memorial Day weekend.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today.
