THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
Scattered to numerous thunderstorms are expected to develop along
the east coast sea breeze in the early to mid afternoon, with
additional stronger storms likely in the late afternoon after the
collision with the west coast sea breeze. Interior locations,
mainly west of Interstate 95, will be the most favored to see
thunderstorms which will be capable of producing wind gusts over
40 mph, frequent lightning and heavy rain.

.FLOOD IMPACT...
Slower storm motion due to lighter steering flow may lead to
stationary thunderstorms which will produce a quick 1 to 2 inches
of rain. This will produce minor flooding of roadways and poorly
drained areas.

.EXCESSIVE HEAT IMPACT...
High temperatures in the mid 90s will combine with higher humidity
values to lead to heat indices of 102 to 106 degrees this
afternoon. If spending time outdoors during the hours of peak
heating, take frequent breaks, wear light colored clothing, and
hydrate often.

.RIP CURRENT IMPACT...
A moderate risk of rip currents will be present at all east
central Florida beaches today. While rip currents are possible all
day, the threat will be highest during the hours surrounding low
tide, from the mid morning through mid afternoon. If venturing
into the surf, only swim within sight of a lifeguard.

.MARINE THUNDERSTORM GUST IMPACT...
Scattered to numerous thunderstorms will be capable of producing
gusty winds to around 30 to 35 knots across inland lakes, the
intracoastal waters and the nearshore Atlantic waters through the
afternoon and early evening. Mariners should be prepared to seek
safe harbor when storms threaten.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY.
Scattered to numerous lightning storms are expected from mid
through late this week. Frequent cloud to ground lightning strikes,
heavy rainfall, and gusty winds over both land and marine areas will
be the main threats with any strong storms that develop.

A moderate risk of rip currents will continue through the end of
the week.

.SPOTTER INFORMATION STATEMENT...
Spotter activation will not be needed today and tonight.

...Scattered Thunderstorms Interior/West This Afternoon...
...Hot and Humid Conditions Continue Across South Florida ...

This hazardous weather outlook is for South Florida.

.DAY ONE...TODAY AND TONIGHT

Thunderstorms: Scattered thunderstorms will develop along the east
and west coast sea breezes today. The greatest chances of thunderstorms
will be across the interior and western sections especially during
the afternoon and evening hours. The strongest storms could contain
gusty winds, frequent lightning, and heavy downpours.

Wind: The strongest thunderstorms this afternoon could contain wind
gusts in excess of 45 mph.

Waterspouts: Waterspouts are possible with any showers or storms over
local South Florida waters.

Temperatures: Heat indices will reach 105 to 108 degrees over most
of South Florida this afternoon, with a few spots as high as 109
across the interior.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

The chances of showers and thunderstorms will be increasing for the
end of the week and into the upcoming weekend as deep tropical
moisture starts to move across the region. The strongest
thunderstorms could contain frequent lightning, gusty winds, and
heavy downpours. With the increase in moisture for the end of the
week, the potential for flooding will increase across the urban and
poor drainage areas during this time frame.

The risk of rip currents across the Atlantic coast beaches could be
increasing for the upcoming weekend due to an increase in easterly
flow.

.SPOTTER INFORMATION STATEMENT...

Widespread spotter activation is not anticipated at this time.

mph, frequent lightning, and a quick 1 to 2 inches of rainfall in

head indoors to safety.

At the central Florida Atlantic beaches, there will be a moderate
risk of rip currents, especially from mid morning through the mid
afternoon. If venturing into the surf, only swim within sight of a
lifeguard, and never swim alone.
