PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE ABERDEEN SD
638 AM CDT FRI APR 24 2015 /538 AM MDT FRI APR 24 2015/

...SOUTH DAKOTA SEVERE WEATHER AWARENESS WEEK...DAY FIVE
...EXTREME HEAT...

IN THE LAST 10 YEARS...A NATIONAL AVERAGE OF 219 PEOPLE HAVE DIED
AS A RESULT OF HEALTH PROBLEMS DIRECTLY RELATED TO EXCESSIVE HEAT.
CONSIDERING THIS DEATH TOLL...THE NATIONAL WEATHER SERVICE HAS
STEPPED UP ITS EFFORTS TO MORE EFFECTIVELY ALERT THE GENERAL
PUBLIC TO THE HAZARDS OF HEAT WAVES.

BASED ON RESEARCH FINDINGS...THE NATIONAL WEATHER SERVICE DEVISED
THE HEAT INDEX (HI). IT IS AN ACCURATE MEASURE OF HOW HOT IT
REALLY FEELS WHEN THE RELATIVE HUMIDITY IS ADDED TO THE ACTUAL
AIR TEMPERATURE. IT IS IMPORTANT TO NOTE...SINCE HEAT INDEX VALUES
WERE DEVISED FOR SHADY...LIGHT WIND CONDITIONS...EXPOSURE TO FULL
SUNSHINE CAN INCREASE VALUES BY UP TO 15 DEGREES.

EACH YEAR...DOZENS OF CHILDREN AND UNTOLD NUMBERS OF PETS LEFT IN
PARKED VEHICLES DIE FROM HYPERTHERMIA. HYPERTHERMIA IS AN ACUTE
CONDITION THAT OCCURS WHEN THE BODY ABSORBS MORE HEAT THAN IT CAN
HANDLE. HYPERTHERMIA CAN OCCUR EVEN ON A MILD DAY. STUDIES HAVE
SHOWN THAT THE TEMPERATURE INSIDE A PARKED VEHICLE CAN RAPIDLY
RISE TO A DANGEROUS LEVEL FOR CHILDREN...PETS AND EVEN ADULTS.
LEAVING THE WINDOWS SLIGHTLY OPEN DOES NOT SIGNIFICANTLY DECREASE
THE HEATING RATE. THE EFFECTS CAN BE MORE SEVERE ON CHILDREN
BECAUSE THEIR BODIES WARM AT A FASTER RATE THAN ADULTS.

HEAT DISORDERS GENERALLY HAVE TO DO WITH A REDUCTION OR COLLAPSE
IN THE ABILITY OF THE BODY TO SHED HEAT BY CIRCULATORY CHANGES AND
SWEATING...IN OTHER WORDS...A CHEMICAL IMBALANCE CAUSED BY TOO MUCH
SWEATING. WHEN HEAT GAIN EXCEEDS THE LEVEL THE BODY CAN REMOVE...OR WHEN
THE BODY CANNOT COMPENSATE FOR FLUIDS AND SALT LOST THROUGH PERSPIRATION...
THE INNER CORE TEMPERATURE OF THE BODY BEGINS TO RISE AND HEAT-RELATED
ILLNESS MAY DEVELOP. RANGING IN SEVERITY...HEAT DISORDERS SHARE ONE
COMMON FEATURE...THE INDIVIDUAL HAS OVER-EXPOSED OR OVER-EXERCISED
FOR HIS/HER AGE AND PHYSICAL CONDITION IN THE EXISTING THERMAL
ENVIRONMENT.

SUNBURN...WITH ITS ULTRAVIOLET RADIATION BURNS...CAN ALSO
SIGNIFICANTLY RETARD THE ABILITY OF SKIN TO SHED EXCESS HEAT.

SAFETY TIPS...
THE NATIONAL WEATHER SERVICE WILL ISSUE ADVISORIES OR WARNINGS WHEN THE
HEAT INDEX IS EXPECTED TO HAVE A SIGNIFICANT IMPACT ON PUBLIC SAFETY.
THE COMMON GUIDELINES FOR THE ISSUANCE OF EXCESSIVE HEAT WARNINGS IS
WHEN THE MAXIMUM DAYTIME INDEX IS EXPECTED TO REACH 110 OR 115...AND
THE NIGHTTIME LOW TEMPERATURE DOES NOT FALL BELOW 75 OR 80 DEGREES.

HERE ARE SOME TIPS TO FOLLOW TO ENSURE THAT HEAT-RELATED PROBLEMS DO NOT
IMPACT YOU...

SLOW DOWN...
STRENUOUS ACTIVITIES SHOULD BE REDUCED...ELIMINATED OR RESCHEDULED
TO THE COOLEST TIME OF THE DAY. INDIVIDUALS AT RISK SHOULD STAY IN
THE COOLEST AVAILABLE PLACE...NOT NECESSARILY INDOORS. DRESS FOR
SUMMER. LIGHTWEIGHT...LIGHT-COLORED CLOTHING REFLECTS HEAT AND
SUNLIGHT...AND HELPS YOUR BODY MAINTAIN NORMAL TEMPERATURES.

PUT LESS FUEL ON YOUR INNER FIRES...
FOODS SUCH AS PROTEINS THAT INCREASE METABOLIC HEAT PRODUCTION
ALSO INCREASE WATER LOSS.

DRINK PLENTY OF WATER OR OTHER NON-ALCOHOLIC FLUIDS...
YOUR BODY NEEDS WATER TO KEEP COOL. DRINK PLENTY OF FLUIDS EVEN
IF YOU DO NOT FEEL THIRSTY. HOWEVER...THOSE WHO SUFFER FROM
EPILEPSY...HEART...KIDNEY OR LIVER DISEASE...ARE ON FLUID
RESTRICTIVE DIETS OR HAVE A PROBLEM WITH FLUID RETENTION...SHOULD
CONSULT A PHYSICIAN BEFORE INCREASING THEIR CONSUMPTION OF FLUIDS.

DO NOT DRINK ALCOHOLIC BEVERAGES OR THOSE WITH HIGH SUGAR CONTENT.

SPEND MORE TIME IN AIR-CONDITIONED PLACES...
AIR CONDITIONING IN HOMES AND OTHER BUILDING MARKEDLY REDUCES
DANGER FROM THE HEAT. IF YOU CANNOT AFFORD AN AIR
CONDITIONER...SPENDING TIME EACH DAY IN AN AIR CONDITIONED
ENVIRONMENT DURING HOT WEATHER AFFORDS SOME PROTECTION.

BE CAREFUL NOT TO GET TOO MUCH SUN. SUNBURN MAKES THE JOB OF HEAT
DISSIPATION THAT MUCH MORE DIFFICULT.
