...EXTREME WIND CHILL...POTENTIALLY LIFE-THREATENING AND OFTEN
OVERLOOKED...

THE COMBINATION OF WIND AND LOW TEMPERATURE IN WINTER CAN BE DEADLY.
THE WIND CHILL INDEX HELPS YOU DETERMINE WHEN DANGEROUS CONDITIONS
DEVELOP THAT COULD LEAD TO FROSTBITE OR HYPOTHERMIA.  IT TAKES INTO
ACCOUNT HEAT LOSS FROM THE HUMAN BODY TO ITS SURROUNDINGS DURING
COLD AND WINDY WEATHER.  THE CALCULATION UTILIZES WIND SPEED IN
MILES PER HOUR AND TEMPERATURE IN DEGREES FAHRENHEIT.  FOR
EXAMPLE...A TEMPERATURE OF MINUS 5 DEGREES OCCURRING WITH A 20 MPH
WIND GIVES A WIND CHILL NEAR MINUS 30 DEGREES.  THIS MEANS THAT YOUR
BODY WILL LOSE HEAT AT THE SAME RATE AS IT WOULD IF THE AIR
TEMPERATURE WERE MINUS 30 DEGREES WITH NO WIND.  WIND CHILL VALUES
NEAR MINUS 25 DEGREES MEAN THAT FROSTBITE IS POSSIBLE WITHIN 15
MINUTES.

FROSTBITE IS THE FREEZING OF SKIN AND THE BODY TISSUE JUST BENEATH
IT. IT FIRST AFFECTS EXPOSED BODY TISSUE WHERE BLOOD CIRCULATION MAY
BE LIMITED SUCH AS YOUR FINGERS... TOES...NOSE AND EARS.  TO
MINIMIZE FROSTBITE...MAKE SURE ALL BODY PARTS ARE WELL COVERED.
WHEN FROSTBITE STARTS...FEELING IS LOST IN THE AFFECTED AREA AND THE
FROZEN TISSUE WILL TAKE ON A WHITE OR PALE APPEARANCE.  IF YOU
SUSPECT YOU ARE EXPERIENCING FROSTBITE...HOLD THE FROSTBITTEN AREA
CLOSELY AGAINST WARM SKIN TO RETURN BLOOD FLOW AND WARMTH TO THE
AFFECTED AREA.

HYPOTHERMIA IS A DANGEROUSLY LOW BODY TEMPERATURE AND IS THE MOST
COMMON WINTER WEATHER KILLER. WHEN YOU HEAR OF A
HIKER...CLIMBER...HUNTER OR A STRANDED TRAVELER PERISHING FROM COLD
WEATHER EXPOSURE...HYPOTHERMIA WAS THE CAUSE.  MOST PEOPLE ARE
SURPRISED TO LEARN THAT HYPOTHERMIA DEATHS CAN OCCUR WITH
TEMPERATURES BETWEEN 30 AND 50 DEGREES.  IF YOU OR YOUR CLOTHING ARE
WET...THEN HYPOTHERMIA BECOMES EVEN MORE LIKELY.

WARNING SIGNS OF HYPOTHERMIA INCLUDE UNCONTROLLABLE
SHIVERING...MEMORY LOSS... DISORIENTATION...SLURRED SPEECH AND
DROWSINESS.  IMMEDIATE MEDICAL ATTENTION SHOULD BE GIVEN TO VICTIMS
SUSPECTED OF SUFFERING FROM HYPOTHERMIA.  IF NO HELP IS
AVAILABLE...THE VICTIM SHOULD BE WARMED SLOWLY WITH WARM LIQUIDS
ALONG WITH DRY CLOTHING AND BLANKETS.

THE NATIONAL WEATHER SERVICE WILL ISSUE WIND CHILL ADVISORIES AND
WARNINGS WHEN A DEADLY COMBINATION OF WIND AND COLD AIR THREATEN.
TO LEARN MORE ABOUT WIND CHILL...VISIT THE NATIONAL WEATHER SERVICE
INTERNET SITE USING LOWER CASE LETTERS: WEATHER.GOV/OM/WINDCHILL.

WHEN COLD WEATHER THREATENS...FOLLOW THESE TIPS FOR SURVIVAL...

STAY DRY...WET CLOTHING RESULTS IN MUCH FASTER HEAT LOSS FROM YOUR
BODY.  WEAR WATERPROOF INSULATED BOOTS.

STAY COVERED...WEAR MITTENS OR GLOVES AND WEAR A HAT. AT LEAST HALF
OF YOUR BODY HEAT IS LOST IF YOUR HEAD IS NOT COVERED.

DRESS LAYERED...TRAPPED AIR BETWEEN LOOSE FITTING CLOTHING HELPS TO
INSULATE.

STAY INFORMED...HAVE A PORTABLE NOAA WEATHER RADIO NEARBY TO KEEP
YOU UP-TO-DATE WITH THE LATEST FORECASTS AND WARNINGS.  USE WIND
CHILL TEMPERATURES TO GUIDE YOU IN DRESSING PROPERLY FOR THE
OUTDOORS.  ON VERY COLD DAYS...MINIMIZE YOUR EXPOSURE TO THE
OUTDOORS IF POSSIBLE.
