THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...THIS AFTERNOON AND TONIGHT.

.DENSE FOG/SMOKE IMPACT...
Smoke from a lightning induced wildfire along Interstate 95 near
Rockledge yesterday continues to burn and smolder. The smoke
will drift into parts of Rockledge and Cocoa. Motorists are
urged to use extra caution and be prepared to stop.

As the wildfire burns well into the day...mixing will help thin and
disperse the smoke.

.THUNDERSTORM IMPACT...
A high coverage of afternoon showers and thunderstorms is expected
today, including over the Space and Treasure Coasts where
lightning storms have been more isolated recently. Initial
development of storms should occur along the sea breeze as it
moves inland from the coast early this afternoon. Coverage and
intensity of storms will increase elsewhere through the remainder
of the afternoon. The primary hazards will be cloud to ground
lightning, gusty winds, and heavy rainfall. Storm motion will be
generally toward the northeast around 10 mph but thunderstorms
that form as a result of boundary collisions will exhibit slow and
erratic movement.

.FLOOD IMPACT...
Slow moving lightning storms will be capable of producing locally
heavy rainfall this afternoon. Rainfall amounts of 2 to 4 inches
in a 60 to 90 minute period will be possible in a few spots which
will cause temporary flooding of roadways and low lying areas.

.RIP CURRENT IMPACT...
An east swell will produce a moderate risk of rip currents at the
beaches of east central Florida. Always swim within sight of a
lifeguard.

.MARINE THUNDERSTORM GUST IMPACT...
Scattered to numerous lightning storms are expected to develop
over the mainland this afternoon. Some of the storms are expected
to push toward the intracoastal and nearshore Atlantic waters.
Mariners are reminded that variable and gusty winds can occur well
away from the heaviest rain of a thunderstorm.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY.
Scattered lightning storms are forecast to continue into the
Fourth of July weekend. The primary threats will be dangerous
lightning strikes, gusty winds, and locally heavy rain. While the
highest chances for afternoon thunderstorms is expected across
inland areas, coastal locations will still see a threat of
lightning activity each day.

A moderate risk of rip currents will continue.

.SPOTTER INFORMATION STATEMENT...
Spotter activation will not be needed today, however spotters are
asked to report rainfall amounts of greater than 3 inches or
observed flooding.
