THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
The east coast sea breeze will push inland rather quickly during
the day. Drier air aloft will limit storm coverage. However,
isolated lightning storms will still develop this afternoon, 
mainly over interior counties as the sea breeze interacts with 
larger lake breeze boundaries. A collision with the west coast sea
breeze should occur around sunset in the vicinity of Lake county.
Frequent lightning strikes will be the primary hazard from storms
today along with wind gusts up to 50 mph and locally heavy
rainfall. 

.MARINE THUNDERSTORM GUST IMPACT...
Isolated to scattered lightning storms this afternoon and evening
will be capable of producing wind gusts 35 to 45 knots over or
near the inland lakes along with frequent lightning. Storm motion
will be toward the northwest or north around 10 knots. 

.EXCESSIVE HEAT IMPACT...
The combination of heat and humidity along with below normal
coverage of showers and storms will produce peak heat indices
between 102 and 105 late this morning through the afternoon. If
working or recreating outdoors, stay hydrated and take frequent
breaks out of the sun.

.RIVER FLOOD IMPACT...
The Saint Johns River at Astor, Sanford, and above Lake Harney 
near Geneva remain above Action Stage. River levels are forecast 
to remain steady or slowly fall into late week.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY.
Moisture will return northward this weekend and this will lead to
a return of scattered lightning storms each afternoon. On
Saturday, the best chance for storms will be confined to  
Okeechobee county and the Treasure coast with lingering dry air 
keeping rain chances below normal farther north. Then scattered
lightning storms are expected areawide Sunday into next week as 
moisture returns. Frequent lightning, gusty winds and heavy 
downpours will be the primary hazards. 

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