...Tropical Depression Three Forms Over the Bahamas...
...Gusty Storms and Locally Heavy Rainfall Possible...

This hazardous weather outlook is for South Florida.

.DAY ONE...TONIGHT

Thunderstorms: Numerous storms will continue across the interior
through the late evening hours.

The passage of Tropical Depression Three just to our east will bring
numerous showers and storms across the local Atlantic waters
overnight. Storms will reach the east coast at times, with more
isolated activity expected over the interior and Gulf coast and
waters. The main threats with any activity will be frequent
lightning, gusty winds, and locally heavy rainfall.

Waterspouts: Isolated waterspouts are possible across the South
Florida waters overnight, mainly on the Atlantic and Lake Okeechobee
waters.

Wind: Stronger showers and storms that develop this evening and
overnight will be capable of producing wind gusts of 40 to 50 mph.

The passage of Tropical Depression Three across the offshore Atlantic
waters will bring sustained winds of 20 to 25 knots starting late
this evening through the overnight hours. A Small Craft Advisory is
in effect for the offshore Palm Beach County waters.

Flooding: Locally heavy rainfall may result in ponding of water in
low lying and poorly drained areas, especially if heavy showers pass
over the same area multiple times.

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

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY

Tropical Depression Three is forecast to move generally parallel
along the east coast of Florida on Tuesday and away from the state
Tuesday night. The influence of this system will continue to bring
numerous showers and storms across the region through the day on
Tuesday.

A frontal boundary is forecast to stall across North and Central
Florida mid to late week bringing a continuing threat for scattered
to numerous storms each day. Frequent lightning, heavy rainfall
leading to street flooding, and gusty winds will be the main
hazards with any storms through the week.

Heat index values could approach 105 degrees over some interior and
western sections, especially during the latter half of the week.

.SPOTTER INFORMATION STATEMENT...

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