to localized flooding in the low lying and poor drainage areas
today.

Tornado: An isolated tornado cannot be ruled out in the strongest
thunderstorms over the interior and east coast.

Marine: A building northeasterly swell in the Atlantic waters will
cause wave heights to build to 8 to 12 feet later tonight creating
hazardous marine conditions.

Beaches, and a moderate risk for the beaches of Broward and Miami
Dade County.

Waterspouts: An isolated waterspout cannot be ruled out with the
strongest thunderstorms over Lake Okeechobee and the Atlantic waters.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday.

The risk of rip currents will increase across all east coast
beaches heading into the upcoming holiday weekend.

Marine conditions will remain hazardous through the holiday weekend
and into next week as the northeasterly swell persists.

Scattered showers and storms remain possible through the weekend and
into next week. Periods of heavy rain will be possible and could
lead to localized flooding concerns especially across the east coast
metro areas.
