THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
Increasing moisture across the region will lead to the development
of isolated to scattered showers and lightning storms into the
the afternoon. Greatest coverage of this activity will be across
the interior and toward the coast of Volusia and northern Brevard
counties from mid to late afternoon where sea breeze and outflow
boundary collisions are favored. Storm motion will generally be
slow and variable, but an east to northeast movement around 10 to
15 mph is possible for convection that develops near to east of
the I-4 corridor.

A few stronger storms will be able to produce frequent lightning
strikes, gusty winds up to 45 mph, and locally heavy rainfall
around 2 inches.

.EXCESSIVE HEAT IMPACT...
The combination of hot temperatures and high humidity today will
again 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.

.MARINE THUNDERSTORM GUST IMPACT...
Scattered storms will develop this afternoon, moving slowly east
to northeast around 5 to 10 knots across inland lakes, and
potentially offshore from the Cape northward late in afternoon
through early evening. A few storms will have the potential to
produce wind gusts in excess of 34 knots.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY.
Expect isolated to scattered coverage of afternoon and evening
lightning storms through Saturday, with a possible increase to
numerous coverage Sunday afternoon into early next week. The main
threats from storms will be frequent lightning, gusty winds, and
torrential downpours.

.SPOTTER INFORMATION STATEMENT...
Spotter activation will not be needed today.

.NOW...

...Hot with Scattered Late Afternoon Thunderstorm...

Another hot and humid day is in store for east central Florida. High
temperatures will reach the mid 90s...except lower 90s along the
coast.  Heat index values will reach 100 to 105 across the entire
area.

All of the heat and humidity will eventually lead to scattered
lightning storms late this afternoon and early evening.  The highest
coverage and strongest storms will be over the interior where
numerous late day boundary interactions occur. Some of these
stronger storms should also affect coastal sections from Cape
Canaveral northward.
