...WIND CHILL ADVISORY REMAINS IN EFFECT UNTIL 8 AM EST FRIDAY...

COLD AIR SPREADING DOWN THE FLORIDA PENINSULA COMBINED WITH
NORTHWEST WINDS AROUND 10 MPH WILL CREATE UNSEASONABLY COLD WIND
CHILL READINGS ACROSS MUCH OF EAST CENTRAL FLORIDA AFTER MIDNIGHT.
LOWEST WIND CHILL TEMPERATURES WILL RANGE FROM AROUND 30 DEGREES
IN NORTH LAKE AND INLAND VOLUSIA COUNTIES TO THE LOWER 30S
EVERYWHERE ELSE EXCEPT INDIAN RIVER...SAINT LUCIE AND MARTIN
COUNTIES WHERE WIND CHILLS ARE FORECAST TO BE IN THE LOWER 40S.

A WIND CHILL ADVISORY MEANS THAT VERY COLD AIR AND STRONG WINDS
WILL COMBINE TO GENERATE LOW WIND CHILLS. THIS WILL RESULT IN
FROST BITE AND LEAD TO HYPOTHERMIA IF PRECAUTIONS ARE NOT TAKEN.
IF YOU MUST VENTURE OUTDOORS...MAKE SURE YOU WEAR A HAT AND
GLOVES.
