THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
Scattered to numerous showers and storms will move quite quickly
across the peninsula from west to east this afternoon.  The
coverage is forecast to be greatest from about Osceola county to
between Cape Canaveral and Vero Beach.

The main weather hazard will be lightning strikes, which will be
frequent in a few strong storms. Brief torrential downpours and
wind gusts to 50 mph are also expected. Storms will approach
relatively fast today, so those with outdoor activities should
keep an eye on the western horizon and be prepared to move to safe
shelter.

.MARINE THUNDERSTORM GUST IMPACT...
Storms will move to the east at 20 to 25 mph and reach the coastal
waters by early afternoon. The latest indication is for the
greatest threat to be from about Osceola county to between Cape
Canaveral and Vero Beach. Wind gusts over 35 knots are expected,
which will prompt Special Marine Warnings for portions of the
coastal waters. Small craft operators should navigate to safe
harbor well in advance of approaching storms.

.RIP CURRENT IMPACT...
A small ocean swell will keep a moderate rip current risk at area
beaches. Only swim in the ocean near a lifeguard.

.EXCESSIVE HEAT IMPACT...
Heat indices between 100 and 105 degrees are expected where
showers and storms hold off the longest this afternoon. If
working outside or engaging in any outdoor activity, be sure to
remain well hydrated, and take frequent rest breaks.

.RIVER FLOOD IMPACT...
The Saint Johns River above Lake Harney near Geneva remains at
Minor Flood Stage, and a River Flood Warning remains in effect
for this area. The Saint Johns River at Astor, Sanford and Deland
remain near or above Action Stage.

Barring additional significant rainfall over the basin or its
headwaters, river levels are forecast to either remain steady or
very slowly fall through early next week.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY.
Scattered to numerous afternoon and evening showers and storms
are expected into the middle of next week. The main storm threats
will continue to be frequent lightning strikes, gusty winds and
torrential downpours producing urban, river, and poor drainage
flooding.

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