This Hazardous Weather Outlook is for West Central And Southwest
Florida.

.DAY ONE...Tonight.

...THUNDERSTORM IMPACT...
Showers and thunderstorms will continue to clear out of the area
from north to south this morning, with some showers possibly
lingering over southwest Florida through the afternoon and early
evening. Some of the stronger storms will be capable of producing
damaging wind gusts and heavy rain with localized flooding.

...EXCESSIVE COLD IMPACT...
A much colder airmass is filling into the area behind a cold front
today. Temperatures tonight will approach freezing over the
northern Nature Coast, and drop into the mid to upper 30s over
interior sections of west central and southwest Florida. Make sure
to dress in layers to protect yourself from the cold.

...RIP CURRENT IMPACT...
High surf and breezy northwest winds will produce stronger and
more frequent rip currents along area beaches today and tonight.

...MARINE IMPACTS...
Sustained wind speeds of 20 to 25 knots will create hazardous
boating conditions for small craft operators today and tonight
across the coastal waters including the Tampa Bay and Charlotte
Harbor. Seas offshore will also build to up to 9 feet. Winds and
seas will subside early on Sunday.

.DAYS TWO THROUGH SEVEN...Sunday through Friday.

...EXCESSIVE COLD IMPACT...
Temperatures will approach freezing over the Nature Coast again
Monday morning with lows in the mid to upper 30s away from the
coast over much of west central and southwest Florida. For many
locations, Monday morning is expected to be slightly cooler than
Sunday morning. Make sure to dress in layers to protect yourself
from the cold.

...MARINE IMPACTS...
Another cold front late Tuesday will cause winds to increase to
around 20 to 25 knots, before conditions subside again on
Wednesday. This will create hazardous boating conditions for
small craft operators.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today.
