THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
Scattered to numerous afternoon and early evening showers and
lightning storms are expected once again across east central
Florida, mainly between about 2 PM and sunset. Storms will
initially form out ahead of the local east and west coast sea
breezes into early to mid afternoon, with additional boundary
collisions creating greater coverage from late afternoon into
early evening. Movement will be slow and erratic. Greatest
coverage from late afternoon into early evening is forecast from
Lake George southward through Osceola County and along the
Kissimmee River into Okeechobee County.

The main storm threats will be cloud to ground lightning strikes,
wind gusts of 35 to 45 mph, and locally heavy rainfall amounts up
to around 2 to 3 inches in a 60 to 90 minute period. Move indoors
to safety if skies look threatening, or you hear thunder.

.EXCESSIVE HEAT IMPACT...
The combination of hot temperatures and high humidity may create
a dangerous situation in which heat illnesses are possible. Drink
plenty of fluids, stay in an air-conditioned room, stay out of the
sun, and check up on relatives and neighbors. Highest heat index
values will soar to between 100 and 106 from late this morning
into early evening across much of east central Florida.

.RIP CURRENT IMPACT...
Ocean conditions will lead to a moderate threat for dangerous rip
currents in the surf zone at east central Florida beaches. The
threat will be highest from this morning into early afternoon and
again around mid evening due to tidal effects. Check with your
local beach patrol for additional information about ocean hazards.
Swim only within sight of a lifeguard, and never swim alone.

.MARINE THUNDERSTORM GUST IMPACT...
A few stronger storms could produce wind gusts up to 35 knots over
some of the larger inland lakes, as well as the Intracoastal and
near shore Atlantic Waters, especially north of Cape Canaveral.

.WATERSPOUT IMPACT...
Marine interests should be alert for the potential of waterspouts.
Showers and lightning storms can produce short-lived waterspouts
with little or no advance warning. Boaters should seek safe harbor
if a waterspout is spotted.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY.
Afternoon lightning storms will remain in the forecast through
the weekend and into early next week. The main thunderstorm
hazards will be frequent cloud to ground lightning, gusty winds,
and locally heavy rainfall. The Rip Current threat is also
expected to remain greater than normal for the next couple days
due to a small lingering swell from distant Hurricane Gert.

.SPOTTER INFORMATION STATEMENT...
Spotter activation is not anticipated today; however, spotters
are encouraged to report any rain amounts of 3 inches or greater.
