THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
The east and west coast sea breezes are expected to form by early
afternoon and push slowly inland. Scattered showers and lightning
storms will form along the breeze boundaries, moving south around
10 mph. Shower and storm coverage will increase during the mid to
late afternoon over the interior counties, with the best chance
for storms expected along and west of the Florida Turnpike

The strongest storms will be capable of producing frequent cloud
to ground lightning strikes, brief wind gusts to around 35 to 45
mph, and rainfall rates up to two inches per hour. Cease outdoor
activities and move indoors if thunder is hear or at the first
sign of threatening skies.

.EXCESSIVE HEAT IMPACT...
Afternoon temperatures in the middle to upper 90s will combine with
light winds and high humidity to generate peak heat indices
around 105 degrees across east central Florida, and high as 110 in
some locations. If you will be outside engaged in any work or
recreational activity today, be sure to stay hydrated and take
frequent rest breaks indoors.

.RIP CURRENT IMPACT...
A small but persistent long period swell coupled with a high
astronomical tide will generate a MODERATE rip currents threat
along the beaches of east central Florida. The threat will be
highest between Noon and 6:30 PM due to tidal effects. To reduce
your chance of being caught in the seaward pull of a rip current,
always swim within sight of a lifeguard and never swim alone.

.MARINE THUNDERSTORM GUST IMPACT...
Lightning storms will be capable of producing wind gusts to
around 35 knots over larger inland lakes, mainly over the interior
counties following the late day collision of the sea breezes.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY.
Storms will increase this weekend into early next week as
moisture increases across Florida. The main storm threats will
continue to be deadly cloud to ground lightning strikes, gusty
winds and local heavy rainfall.

Low daytime cloud cover and rain chances will result in abnormally
hot temperatures through the late week. Afternoon heat indices of
around 105 degrees or so are forecast.

.SPOTTER INFORMATION STATEMENT...
Spotter activation is not anticipated.
