THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TONIGHT.

.HIGH WIND IMPACT...
Gusty north winds will persist behind the cold front. Wind gusts
of 30 to 35 mph will continue along the Volusia county and Space
coasts this evening and overnight. A wind advisory is in effect
for Brevard and coastal Volusia counties this evening through
early Tuesday morning. Gusts 25 to 30 mph could also reach inland
to the Interstate 4 corridor late into this evening, as well as
Treasure Coast this evening and overnight.

.EXCESSIVE COLD IMPACT...
Wind chill values tonight are forecast to drop into the 30s near and
west of Interstate 4, with some mid to upper 20s possible late
mainly across Lake county. A wind chill advisory is now in effect
through Tuesday morning for Lake county and in effect late tonight
through Tuesday morning for inland Volusia county and western
portions of Seminole and Orange counties. Make sure to dress
appropriately for these much colder than normal conditions.

.WIND AND SEA IMPACT...
Very hazardous boating conditions behind a cold front that moved
through central Florida today. Gale warnings are in effect for all
marine areas.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY.
Hazardous beach and boating conditions will continue through mid
week due to an extended period of gusty northeast to north winds.
Large breaking waves and higher than normal astronomical tides
could lead to minor beach erosion.

There is also a potential for freezing temperatures late in the
week due to a strengthening low pressure center offshore that
will lift northeast and pull very cold air down into central
Florida.

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