SPECIAL WEATHER STATEMENT
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
200 PM EST SUN AUG 9 1992

...THE HEAT INDEX WILL BE IN THE 107 TO 112 DEGREE RANGE THIS
AFTERNOON OVER SOUTHERN INDIANA...

THE COMBINATION OF AFTERNOON TEMPERATURES IN THE LOWER AND MIDDLE 90S
AND HUMIDITIES IN THE 60 TO 65 PERCENT RANGE WILL PUSH THE HEAT INDEX
INTO THE 107 TO 112 DEGREE RANGE.

THE HEAT INDEX IS THE APPARENT TEMPERATURE THAT THE HUMAN BODY FEELS
WHEN EXPOSED TO A COMBINATION OF HIGH HUMIDITY AND HIGH TEMPERATURE.
IT REDUCES THE HUMAN BODY/S NATURAL ABILITY TO COOL ITSELF AND COULD
BE LIFE THREATENING TO THOSE WORKING OUTDOORS BUT ESPECIALY TO THE
ELDERLY.

TO PREVENT SUNSTROKE...HEAT CRAMPS OR HEAT EXHAUSTION ONE HAS TO DRESS
LIGHTLY AND DRINK PLENTY OF LIQUIDS. OUTDOOR ACTIVITIES SHOULD BE EITHER
ELIMINATED OR PERFORMED IN A SLOW MANNER. STAY IN THE SHADE AS MUCH
AS POSSIBLE. GO INTO AN AIR CONDITIONED ROOM AT INTERVALS TO ENABLE
THE BODY TO COOL DOWN.
