...Heavy Rainfall and Localized Flooding Possible...
...Scattered to Numerous Thunderstorms Today...

.DAY ONE...Today and tonight.

Thunderstorms: Scattered showers and thunderstorms are expected
today, peaking during the afternoon and early evening hours. A few
strong storms are possible, with gusty winds and frequent lightning
the main threats. A few strong to severe thunderstorms are possible
with strong wind gusts being the main hazard. Given the messy nature
of boundary collisions, a funnel cloud or brief tornado cannot be
ruled out.

Excessive Rainfall: Some of the storms today could produce heavy
rainfall, resulting in chances for localized street flooding across
the east coast metro areas.

Waterspouts: A few waterspouts are possible today across the local
waters.

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

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

.SPOTTER INFORMATION STATEMENT...

Weather spotters are encouraged to report high wind, hail, and
flooding to the National Weather Service forecast office in Miami
while following all local, state, and CDC guidelines.
