THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
Scattered lightning storms are forecast today. These will produce
occasional to frequent lightning, gusty winds from 35 to 45 mph,
and locally heavy rain. There is a Marginal Risk that repeated
storms will cause excessive rainfall of 2 to 4 inches on an
isolated basis. This could lead to localized flooding of urban
and poor drainage areas.

.HIGH WIND IMPACT...
As Tropical Storm Debby remains to the north of our local area,
southwest wind gusts from 25 to 35 mph are forecast today. Keep
loose, lightweight items secured.

.EXCESSIVE HEAT IMPACT...
We will turn hotter this afternoon, with low 90s forecast. Heat
index readings should top out from 100 to 107 degrees. Stay
hydrated, and seek breaks in the shade or air conditioning if you
begin to feel unwell.

.RIP CURRENT AND SURF IMPACT...
There is a Moderate Risk of life-threatening rip currents at
Atlantic beaches. Remember to always swim in front of a lifeguard,
and never swim alone.

.WIND AND SEA IMPACT...
Strong offshore winds from 20 to 30 knots will only slowly subside
today, particularly offshore. A Small Craft Advisory remains in
effect for the entire local Atlantic until this afternoon. By this
evening, the Small Craft Advisory will continue over the offshore
waters and nearshore Volusia County.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY.
Even hotter temperatures are forecast from mid to late this week
as rain chances decrease. Highs in the mid 90s, combined with
seasonably high humidity, will result in heat indices from 102 to
107 on Wednesday, then 105 to 110 on Thursday and Friday. This
Major Heat Risk affects anyone without adequate access to cooling.

While storm chances lessen from Wednesday into Thursday, any
strong storm that develops will produce gusty winds to 45 mph and
frequent lightning.

A Moderate Risk of rip currents will continue at our beaches on
Wednesday.

Boating conditions will improve nearshore first, then offshore
later this week as winds slowly subside.

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