.DAY ONE...TONIGHT

Thunderstorms: Numerous showers and thunderstorms are expected this

Wind: A few storms could become strong to severe and produce damaging wind
gusts in the 50 to 60 mph range this evening.

Waterspouts: There is a slight chance of waterspouts over the local
South Florida waters.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

Scattered to numerous showers and thunderstorms are possible each
day with increased potential for flooding across the metro areas of
South Florida on Sunday and Monday. Frequent lightning, heavy
downpours, and gusty winds will be possible with the strongest
thunderstorms.

.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.
