...EXCESSIVE HEAT WATCH IN EFFECT FROM TUESDAY AFTERNOON THROUGH
WEDNESDAY EVENING...

THE NATIONAL WEATHER SERVICE IN MOUNT HOLLY HAS ISSUED AN
EXCESSIVE HEAT WATCH...WHICH IS IN EFFECT FROM TUESDAY AFTERNOON
THROUGH WEDNESDAY EVENING. 

ANOTHER ROUND OF NEAR RECORD HEAT...COMBINED WITH INCREASING
HUMIDITY TUESDAY AND WEDNESDAY...WILL RESULT IN HEAT INDEX VALUES
REACHING OR EXCEEDING 100 DEGREES FOR A FEW HOURS BOTH AFTERNOONS.

ANOTHER HEAT WAVE IS STARTING ACROSS THE REGION THIS AFTERNOON...
AND WILL CONTINUE FOR MOST OF THE UPCOMING WEEK. HIGHS MONDAY WILL
TOP OUT IN THE MID TO UPPER 90S...WITH A FEW 100 DEGREE READING
POSSIBLE. HOWEVER...HUMIDITY VALUES WILL STILL BE COMPARATIVELY
LOW...SO HEAT INDEX VALUES MONDAY AFTERNOON WILL ACTUALLY BE A
COUPLE OF DEGREES LOWER THAN THE AIR TEMPERATURE.

INCREASING HUMIDITY VALUES ARE EXPECTED TUESDAY AND PARTICULARLY
WEDNESDAY. HIGH TEMPERATURES BOTH DAYS AS EXPECTED TO TOP OUT NEAR
100 DEGREES IN MANY PLACES. THE INCREASED HUMIDITY WILL SEND HEAT
INDEX VALUES TO NEAR 102 DEGREES BOTH TUESDAY AND WEDNESDAY
AFTERNOON. LOWS TUESDAY NIGHT MAY NOT DROP BELOW THE 80 DEGREE
MARK.

WITH LITTLE IN THE WAY OF SIGNIFICANT RELIEF IN SIGHT...HEAT 
INDEX VALUES MAY APPROACH OR EXCEED 100 DEGREES FOR A TIME
THURSDAY AFTERNOON AS WELL.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

AN EXCESSIVE HEAT WATCH MEANS THAT A PROLONGED PERIOD OF HOT
TEMPERATURES IS EXPECTED. THE COMBINATION OF HOT TEMPERATURES AND
HIGH HUMIDITY WILL COMBINE TO CREATE A DANGEROUS SITUATION IN
WHICH HEAT ILLNESSES ARE POSSIBLE. DRINK PLENTY OF FLUIDS...STAY
IN AN AIR-CONDITIONED ROOM...STAY OUT OF THE SUN...AND CHECK UP
ON RELATIVES AND NEIGHBORS.
