PUBLIC INFORMATION STATEMENT 
NATIONAL WEATHER SERVICE GRAY ME
0752 AM EST WED NOV 05 2014

THE NATIONAL WEATHER SERVICE OFFICES THAT SERVE NEW ENGLAND 
HAVE DECLARED THE WEEK OF NOVEMBER 3RD THROUGH 7TH, WINTER 
WEATHER AWARENESS WEEK.  IN CONJUNCTION WITH WINTER WEATHER 
AWARENESS WEEK, THE NATIONAL WEATHER SERVICE OFFICE IN GRAY 
WILL BE ISSUING PUBLIC INFORMATION STATEMENTS CONCERNING 
MANY ASPECTS OF WINTER WEATHER AND WINTER WEATHER 
PREPAREDNESS.  THIS IS THE THIRD IN A SERIES OF FIVE PUBLIC 
INFORMATION STATEMENTS TO BE ISSUED THIS WEEK.


...EXTREME COLD, HYPOTHERMIA, FROSTBITE, AND WIND CHILL...

COLD AIR, STRONG WINDS, AND COLD WIND CHILL TEMPERATURES ARE 
COMMON IN NORTHERN NEW ENGLAND DURING WINTER.  HOWEVER, IF 
YOU ARE NOT PREPARED, THESE COLD CONDITIONS CAN LEAD TO 
HYPOTHERMIA, FROSTBITE, AND POSSIBLY DEATH.  TO UNDERSTAND 
THE DANGERS AND WARNING SIGNS ASSOCIATED WITH THE COLD, 
LET'S EXAMINE HOW THE HUMAN BODY REGULATES ITS TEMPERATURE.


...HYPOTHERMIA...

THE HUMAN BODY LOSES HEAT DURING THE WINTER DUE TO THE 
CONDUCTION AND CONVECTION OF HEAT FROM THE SKIN TO NEARBY 
AIR, DUE TO EVAPORATION OF MOISTURE FROM THE SKIN SURFACE, 
AND DUE TO NORMAL RESPIRATION.  TO COMPENSATE FOR THIS HEAT 
LOSS, THE BODY BURNS ENERGY TO PRODUCE HEAT TO KEEP THE BODY 
TEMPERATURE AT A RELATIVELY CONSTANT LEVEL.  HOWEVER, IF A 
BODY LOSES HEAT FASTER THAN IT CAN PRODUCE HEAT, THE BODY 
TEMPERATURE WILL COOL TO BELOW NORMAL LEVELS, A MEDICAL 
CONDITION KNOWN AS HYPOTHERMIA.

HYPOTHERMIA WILL GRADUALLY WORSEN UNLESS THE OVERALL RATE 
OF HEAT LOSS CAN BE STOPPED.  THE WARNING SIGNS FOR 
HYPOTHERMIA MAY START WITH SHIVERING AND SHAKING AND MAY END 
IN DEATH.  INITIALLY, AS THE BODY TEMPERATURE STARTS TO 
DROP, SHIVERING BEGINS.  AT THE SAME TIME, THE BRAIN BEGINS 
TO REDUCE THE AMOUNT OF BLOOD THAT IS CIRCULATED TO THE 
EXTREMITIES OF THE BODY IN ORDER TO CONSERVE HEAT FOR THE 
VITAL ORGANS NEAR THE BODY'S CENTRAL CORE.  IF THE CENTRAL 
CORE OF THE BODY CONTINUES TO COOL, UNCONTROLLABLE SHAKING, 
MEMORY LOSS, DISORIENTATION, INCOHERENCE, SLURRED SPEECH, 
DROWSINESS, AND APPARENT EXHAUSTION MAY DEVELOP.  THESE ARE 
ALL SIGNS OF A VERY SERIOUS SITUATION.  IF THE BODY CORE 
TEMPERATURE DROPS BELOW 95 DEGREES FAHRENHEIT, JUST 4 
DEGREES BELOW NORMAL, IMMEDIATE CARE IS NEEDED, AS THE 
PERSON WILL LIKELY BECOME IRRATIONAL.  ONCE THE BODY CORE 
TEMPERATURE DROPS BELOW 90 DEGREES, THE PERSON LOSES MUSCLE 
CONTROL, AND OUTSIDE HELP IS THE PERSON'S ONLY HOPE FOR 
SURVIVAL.  IF THAT HELP IS NOT AVAILABLE, HEART AND/OR 
RESPIRATORY FAILURE AND DEATH WILL EVENTUALLY FOLLOW AS THE 
CORE TEMPERATURE CONTINUES TO DROP.

IF A PERSON IS SUFFERING FROM HYPOTHERMIA, IT'S CRITICALLY 
IMPORTANT THAT THE PERSON BE WARMED PROPERLY.  IF WARMED 
IMPROPERLY, DEATH MAY RESULT.  IN A HYPOTHERMIC PERSON, 
COLD BLOOD IS CONCENTRATED IN THE EXTREMITIES.  IF THESE 
EXTREMITIES ARE WARMED TOO QUICKLY, THIS COLD BLOOD WILL BE 
RELEASED INTO THE BODY'S CENTRAL CORE, POSSIBLY LOWERING THE 
CENTRAL CORE TEMPERATURE TO A FATAL LEVEL.  USE THE 
FOLLOWING STEPS TO RAISE THE CORE TEMPERATURE OF A 
HYPOTHERMIC PERSON.

   GET THE PERSON INTO DRY CLOTHING IF THEIR CLOTHES ARE
   WET.

   PUT ON ADDITIONAL CLOTHING TO WARM THE PERSON'S HEAD 
   AND TRUNK, SUCH AS A HAT AND VEST.  

   WRAP THE PERSON IN A WARM BLANKET AND BE SURE THEIR HEAD 
   AND NECK ARE COVERED.  DO NOT COVER THEIR EXTREMITIES.

   GIVE THEM WARM LIQUIDS TO DRINK, BUT NO ALCOHOL, DRUGS, 
   OR COFFEE.

   SEEK MEDICAL ATTENTION, IF NECESSARY. 

REMEMBER, TEMPERATURES DO NOT HAVE TO BE BELOW FREEZING FOR 
HYPOTHERMIA TO DEVELOP.  THE COMBINATION OF TEMPERATURE, 
WIND, AND EXPOSURE TO THE ELEMENTS CAN BE DEADLY.  
HYPOTHERMIA CAN DEVELOP IN ELDERLY PEOPLE IN A COOL ROOM WITH 
FEW, IF ANY, WARNING SIGNS.

...FROSTBITE...

FROSTBITE IS A CONDITION IN WHICH THE BODY TISSUE ACTUALLY 
FREEZES. FROSTBITE IS OFTEN ASSOCIATED WITH HYPOTHERMIA.  
IN A HYPOTHERMIC PERSON, THE BRAIN GREATLY REDUCES THE 
AMOUNT OF BLOOD THAT IS CIRCULATED TO THE EXTREMITIES OF THE 
BODY AND THEY BEGIN TO COOL.  THIS INCREASES THE CHANCES 
THAT THE TISSUE AT THE END OF THE EXTREMITY MAY ACTUALLY 
FREEZE.  THE MOST SUSCEPTIBLE AREAS FOR FROSTBITE INCLUDE 
THE FINGERS, TOES, NOSE, AND EAR LOBES.


...WIND CHILL TEMPERATURE...

COLD AIR AND HIGH WINDS CONTRIBUTE THE POSSIBILITY THAT A 
PERSON MAY DEVELOP HYPOTHERMIA OR FROSTBITE.  TO HELP 
MEASURE THE COOLING EFFECTS OF WIND AND COLD AIR ON THE HUMAN 
BODY, A VALUE KNOWN AS THE WIND CHILL TEMPERATURE WAS 
DEVELOPED.  WHILE INANIMATE OBJECTS ARE NOT AFFECTED BY 
WIND CHILL, WARM BLOODED ANIMALS, INCLUDING HUMANS, ARE 
SUSCEPTIBLE TO THE COOLING AFFECTS FROM THE WIND.

TO ALERT PEOPLE TO THE DANGERS ASSOCIATED WITH THE 
COMBINATION OF WIND AND COLD TEMPERATURES, THE NATIONAL 
WEATHER SERVICE ISSUES WIND CHILL WARNINGS AND WIND CHILL 
ADVISORIES.  THE FOLLOWING VALUES ARE USED FOR ALL OF NEW 
HAMPSHIRE AND WESTERN AND SOUTHERN MAINE.

  WIND CHILL WARNINGS -   ISSUED FOR WIND CHILL TEMPERATURES
                          OF -30 DEGREES OR COLDER 

  WIND CHILL ADVISORIES - ISSUED FOR WIND CHILL TEMPERATURES
                          BETWEEN -20 AND -30 DEGREES

EXTREMELY COLD TEMPERATURES, EVEN WITHOUT WIND, ALSO 
INCREASE THE THREAT OF FROSTBITE, ESPECIALLY IF YOU ARE 
OUTSIDE OVER AN EXTENDED PERIOD OF TIME.  BE SURE TO DRESS 
APPROPRIATELY FOR ANY OUTSIDE ACTIVITIES ON COLD DAYS.


PREPAREDNESS TIP FOR THE DAY:

DURING VERY COLD AND WINDY DAYS, WEAR LAYERED CLOTHING.  
EACH LAYER OF CLOTHING TRAPS A SMALL AMOUNT OF AIR THAT HELPS 
INSULATE THE BODY FROM THE OUTSIDE COLD AND WIND.  THE TOP 
LAYERS WILL CUT DOWN ON THE PENETRATION OF THE WIND, ALLOWING 
THE LOWER LAYERS TO TRAP HEAT, THUS LOWERING THE AMOUNT OF 
HEAT THAT THE WIND CAN CARRY AWAY FROM THE BODY.


QUESTION OF THE DAY:

DOES THE WIND CHILL TEMPERATURE AFFECT MY CAR OR CAR BATTERY?  
WILL MY CAR BE HARDER TO START WHEN THE WIND CHILL 
TEMPERATURE IS COLD?

  ANSWER: NO TO BOTH QUESTIONS.  YOUR CAR AND YOUR CAR'S 
  BATTERY ARE AFFECTED ONLY BY THE ACTUAL 
  TEMPERATURE.  WIND CHILL TEMPERATURES ARE A 
  MEASURE OF THE RATE OF HEAT LOSS FROM THE HUMAN 
  BODY.  FOR A CAR LEFT OVERNIGHT, THE TEMPERATURE 
  OF THE CAR IS APPROXIMATELY THE SAME AS THE 
  SURROUNDING AIR, SO THERE WOULD BE NO ADDITIONAL 
  HEAT LOSS DUE TO WIND, HENCE NO WIND CHILL.  IN 
  GENERAL, MORNING TEMPERATURES ARE COLDEST ON 
  NIGHTS WITH LITTLE OR NO WIND.  THEREFORE, YOUR 
  CAR BATTERY IS MORE LIKELY TO FAIL ON A NIGHT WITH 
  LITTLE OR NO WIND THAN A WINDY NIGHT.

WEATHER AWARENESS WEEK.
