...Scattered Thunderstorms This Afternoon/Evening...
...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, small hail, frequent lightning, and heavy downpours.

Wind: The strongest thunderstorms this afternoon and evening could
contain wind gusts in excess of 50 mph.

Hail: Small hail is possible in strongest thunderstorms this
afternoon and evening.

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.
