THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
Scattered showers are expected to develop into lightning storms
during the late afternoon and evening hours, as the east and west
coast sea breeze boundaries push slowly inland, interact with the
larger lake breeze boundaries and eventually collide on the east
side of the peninsula this evening. Activity is then expected to
drift back towards the coast into tonight. Storm motion will be
toward the east to northeast at 15 to 25 mph. The primary threats
from storms today will be occasional lightning strikes, gusty
winds up to 40 mph and heavy rain.

.RIP CURRENT IMPACT...
A Moderate risk of dangerous rip currents continues at all
central Florida Atlantic beaches. Check with the local beach
patrol for additional information about ocean hazards and heed
the advice of lifeguards. Always swim near a lifeguard and never
swim alone.

.MARINE THUNDERSTORM GUST IMPACT...
Storms that form this afternoon and evening will move toward the
east or northeast at 15 to 20 knots and affect portions of the
inland lakes, intracoastal, and nearshore Atlantic waters. Wind
gusts up to 35 knots will be possible in the stronger storms.

.WIND AND SEA IMPACT...
North to northwest winds will increase 15 to 20 knots behind a
cool front late tonight over the Volusia waters. Seas up to 6 feet
will be possible late tonight well offshore north of the Cape.

.FIRE WEATHER IMPACT...
The fire weather danger remains high today across east central
Florida, inland from I-95, due to a combination of ongoing
drought conditions and low afternoon relative humidity. Outdoor
burning remains highly discouraged! Temporary burn bans are in
effect for Brevard, Orange, Osceola, Seminole, and Lake counties.
Remember to dispose of cigarette butts in their proper receptacles
and never discard them outdoors or throw them out of car windows.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY.
Increasing north then northeast winds behind a cold frontal
passage Sunday will result in windy conditions along the coast,
with very hazardous boating and surf conditions through early next
week. Breaking waves of 6 to 8 feet, and possibly higher, will
produce rough surf and beach erosion around the times of high tide
beginning late Sunday and continuing through at least Tuesday.
The Volusia coast is especially vulnerable to wave runup given the
loss of dunes and seawalls as a result of tropical cyclones Ian
and Nicole last year.

An unsettled pattern will continue this week with scattered to
numerous showers and isolated storms each day.

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