THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...THIS AFTERNOON AND TONIGHT.

.THUNDERSTORM IMPACT...
Scattered lightning storms are expected to develop this afternoon
from Kissimmee to Titusville northward, though a few storms are
also possible from Melbourne to Okeechobee. The strongest storms
are going to produce frequent lightning strikes, wind gusts up to
50 mph, and torrential downpours. Be sure to seek safe shelter
inside a sturdy building at the first sign of bad weather, if you
see lightning, or if you hear thunder.

Locally heavy rainfall amounts of 2 to 3 inches are possible from
Titusville to Kissimmee northward. This could cause minor
flooding of urban and poor drainage areas.

.EXCESSIVE HEAT IMPACT...
Afternoon temperatures are forecast to reach the low to mid 90s.
Combined with high humidity, expect peak heat index values between
105 to 107. If outdoors this afternoon, be sure to take plenty of
breaks in an air conditioned room, stay hydrated, and wear light
colored clothing.

.RIP CURRENT IMPACT...
There is a moderate risk of rip currents at all Central Florida
Atlantic beaches today. Always swim near a life guard and never
swim alone.

.MARINE THUNDERSTORM GUST IMPACT...
Scattered lightning storms this afternoon and early evening will
be capable of producing wind gusts of 35 knots or greater on
inland lakes, the Intracoastal Waterway, and nearshore Atlantic
waters north of Sebastian Inlet.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY.
Scattered showers and lightning storms are forecast each afternoon
for the rest of this week and weekend, with the highest coverage
of storms being west of Interstate 95. The main threats from any
strong storms will be frequent cloud to ground lightning strikes,
torrential downpours, and gusty winds.

The rip current risk is expected to remain moderate through the
weekend.

.SPOTTER INFORMATION STATEMENT...
Spotter activation will not be needed this afternoon and tonight.
