THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...THIS AFTERNOON AND TONIGHT.

.THUNDERSTORM IMPACT...
Numerous lighting storms will develop over east central Florida this
afternoon as storms move in from the west and collide with the east
coast sea breeze. Weak steering level winds out of the southwest
will lead to slow storm movement and the chance of locally heavy
rain and frequent cloud to ground lightning. The activity will
continue over the Atlantic waters into early evening. A few strong
storms are expected especially where boundary collisions occur,
containing wind gusts up to 50 mph, small hail and frequent to
excessive lightning strikes.

.FLOOD IMPACT...
Locally heavy rainfall accumulating up to 4 inches will cause
standing water on some roads and low lying areas. Areas that have
seen multiple rounds of heavy rain over the past several days will
be most vulnerable to flooding.

.MARINE THUNDERSTORM GUST IMPACT...
Scattered to numerous lightning storms are expected to impact the
inland lakes this afternoon followed by the intracoastal and near
shore Atlantic waters as storms move in from the west and southwest.
Gusty winds exceeding 35 knots and frequent lightning strikes are
the main hazards. Boaters are reminded that sudden changes in wind
speed and direction can occur well ahead of the heaviest rain from a
lightning storm. Seek safe harbor in advance of storms.

.RIVER FLOOD IMPACT...
Due to recent heavy rain, Shingle Creek at Campbell has risen to
within one foot of flood stage. Additional heavy rain in the
immediate area today may cause an additional rise of the creek.
Residents near Shingle Creek in Campbell City, Poinciana and
Intercession City should remain alert to changes in the creek level
and listen to advice from local authorities.

.RIP CURRENT IMPACT...
A small east swell will produce a Moderate Risk of rip currents
at the beaches of east central Florida this afternoon. Always swim
within sight of a lifeguard.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY.
Scattered lightning storms are expected each afternoon well into
next week. The primary threats will be dangerous cloud to ground
lightning and gusty winds. Slow moving storms will also produce
very heavy rains resulting in temporary flooding of some roads and
poor drainage areas.

.SPOTTER INFORMATION STATEMENT...
Spotters are requested to monitor the weather and self activate
if needed.
