THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

...EXCESSIVE COLD IMPACT...
THE COMBINATION OF COLD TEMPERATURES WITH NIGHTTIME LOWS GETTING INTO
MID AND UPPER 30S TO LOWER 40S IN MOST AREAS...AND LIGHT TO CALM WINDS
WILL LEAD TO THE FORMATION OF AREAS OF FROST FROM RURAL OUTLYING AREAS
OF OSCEOLA COUNTY NORTHWARD TO THE OCALA FOREST AND LAKE GEORGE...WITH
THE EXCEPTION OF THE URBAN METRO ORLANDO AREA...WHERE THE FROST IS
MORE LIKELY TO BE PATCHY IN NATURE. PATCHY FROST IS ALSO POSSIBLE
AS FAR SOUTH AS LAKE OKEECHOBEE AND RURAL WESTERN MARTIN COUNTY.

MEASURES SHOULD BE TAKEN TO PROTECT COLD SENSITIVE PLANTS AND PETS
FROM THE COLD AND FROST. BEFORE RETIRING FOR THE EVENING...BRING THOSE
PLANTS THE CAN BE EASILY MOVED INDOORS...AND COVER THOSE THAT CANNOT.
PETS SHOULD BE BROUGHT INDOORS FOR THE NIGHT. FINALLY...BE VERY
CAREFUL WHEN USING INDOOR SPACE HEATERS.

...WIND AND SEA IMPACT...
NORTHERLY WINDS NEAR 20 KNOTS WILL PRODUCE SEAS OF 7 TO 8 FEET IN
THE GULF STREAM FROM THIS MORNING INTO THE AFTERNOON. BOTH WINDS
AND SEAS WILL BEGIN TO SUBSIDE LATE TODAY AND TONIGHT.

...FIRE WEATHER IMPACT...
THE COMBINATION OF DRY VEGETATION AND DRY AIR WILL CONTINUE TO
ENHANCE THE FIRE DANGER THIS AFTERNOON.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY.
CHILLY WEATHER WILL CONTINUE INTO THE MIDDLE TO LATTER PART OF
NEXT WEEK. FIRE SENSITIVITY WILL CONTINUE TO BE ENHANCED FOR THE
FORESEEABLE FUTURE.

.SPOTTER INFORMATION STATEMENT...
SPOTTER ACTIVATION WILL NOT BE NEEDED TODAY.
