...Scattered Afternoon Thunderstorms Mainly Interior/West Coast...
...Heat indices Over 105 Possible Across Interior/West Coast...

This hazardous weather outlook is for South Florida.

.DAY ONE...TODAY AND TONIGHT

Thunderstorms: Scattered showers and thunderstorms will develop along
the east and west coast sea breezes. The greatest coverage of storms
will focus across the interior and west coast sections this
afternoon. The strongest storms could contain heavy downpours, gusty
winds, and frequent lightning.

Wind: The strongest thunderstorms today will be capable of producing
wind gusts of up to 50 mph over the interior and west coast this
afternoon.

Flooding: Saturated ground across much of the region will mean any
thunderstorms that produce heavy rain will bring the threat for at
least minor flooding of streets and poor drainage areas across the
interior and west coast.

Temperatures: Warm and humid conditions will continue to produce
late morning and early afternoon heat index readings over 100
degrees for all of South Florida. Portions of South Florida,
especially across Collier, interior Miami-Dade, and Palm Beach
counties will see the highest values reach 105 to possibly 110
degrees for an hour or two around midday.



.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY
More numerous thunderstorms are expected to return for all of South
Florida early this upcoming week. Frequent lightning, heavy rain
capable of producing localized flooding, and gusty winds will
continue to be the main hazards.

Heat indices may reach around 105 to 108 degrees for a few hours in
the late morning and early afternoon through the upcoming week next
week.


.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.
