...EXCESSIVE HEAT WATCH REMAINS IN EFFECT FROM MONDAY AFTERNOON
THROUGH MONDAY EVENING...

A HEAT ADVISORY REMAINS IN EFFECT UNTIL 8 PM EDT THIS EVENING. AN
EXCESSIVE HEAT WATCH REMAINS IN EFFECT FROM MONDAY AFTERNOON
THROUGH MONDAY EVENING. 

TEMPERATURES ARE EXPECTED TO TOP OUT AROUND 95 DEGREES THIS 
AFTERNOON, AND THE MID TO UPPER 90S ON MONDAY. THESE HOT 
TEMPERATURES COMBINED WITH AN INCREASE IN THE HUMIDITY WILL PRODUCE 
HEAT INDEX VALUES WELL INTO THE 90S THIS AFTERNOON, WITH THE HIGHLY 
URBANIZED AREAS APPROACHING 100 DEGREES. ON MONDAY, THE HUMIDITY 
ALONG WITH THE HIGH TEMPERATURES ARE FORECAST TO BE A LITTLE HIGHER, 
THEREFORE THE HEAT INDEX VALUES WILL BE AROUND 100 DEGREES IN THE
AFTERNOON.

HEAT INDEX VALUES AROUND 100 DEGREES CAN CREATE A SITUATION IN WHICH 
HEAT ILLNESSES ARE POSSIBLE, ESPECIALLY IF THIS OCCURS OVER A NUMBER 
OF DAYS. ADDITIONALLY, OVERNIGHT LOW TEMPERATURES WILL REMAIN QUITE 
WARM, WITH MID 70S STARTING TONIGHT IN THE URBAN AREAS AND AROUND 70 
ELSEWHERE.

TO STAY SAFE DURING THE HOT AND HUMID WEATHER, FOLLOW SOME COMMON 
SENSE SAFETY RULES TO AVOID HEALTH PROBLEMS. THESE INCLUDE, WEAR 
LIGHT-COLORED AND LOOSE-FITTING CLOTHING, DRINK PLENTY OF 
NON-ALCOHOLIC FLUIDS, STAY OUT OF THE SUNSHINE, STAY IN AN AIR 
CONDITIONED OR WELL VENTILATED PLACE, AND CHECK ON ELDERLY RELATIVES 
AND NEIGHBORS. ALSO, AVOID STRENUOUS OR PROLONGED WORK IN THE 
SUNSHINE OR IN POORLY VENTILATED AREAS. DO NOT ASSUME THAT CHILDREN 
AND TEENAGERS IN CAMPS OR PARTICIPATING IN SPORTS TOURNAMENTS ARE 
IMMUNE TO THE EFFECTS OF THE HEAT. MAKE SURE THEY DRINK PLENTY OF 
FLUIDS AND GIVE SERIOUS CONSIDERATION TO LIMITING OR POSTPONING 
STRENUOUS ACTIVITIES. ALSO, MAKE SURE THAT PETS AND ANIMALS HAVE 
ACCESS TO A SHADY AND WELL VENTILATED PLACE WITH PLENTY OF COOL 
WATER.

NEVER LEAVE ANY PERSON OR ANIMAL UNATTENDED IN A VEHICLE FOR ANY
LENGTH OF TIME.

A HEAT ADVISORY MEANS THAT A PERIOD OF HOT TEMPERATURES IS
EXPECTED. THE COMBINATION OF HOT TEMPERATURES AND HIGHER HUMIDITY
WILL COMBINE TO CREATE A SITUATION IN WHICH HEAT ILLNESSES ARE 
POSSIBLE.

AN EXCESSIVE HEAT WATCH MEANS THAT THE COMBINATION OF HEAT AND
HUMIDITY WILL ELEVATE THE RISK OF MORE SERIOUS HEAT RELATED
ILLNESSES INCLUDING HEAT STROKE.

...EXCESSIVE HEAT WARNING IN EFFECT FROM 12 PM MONDAY TO 6 PM EDT
TUESDAY...
...HEAT ADVISORY IS CANCELLED...

THE NATIONAL WEATHER SERVICE IN MOUNT HOLLY HAS ISSUED AN
EXCESSIVE HEAT WARNING...WHICH IS IN EFFECT FROM NOON MONDAY TO
6 PM EDT TUESDAY. THE HEAT ADVISORY THAT WAS IN EFFECT FOR SUNDAY 
HAS BEEN CANCELLED. THE EXCESSIVE HEAT WATCH IS NO LONGER IN
EFFECT.

TEMPERATURES REACHED THE LOWER AND MIDDLE 90S TODAY. HOWEVER, AS
THE TEMPERATURES PEAKED, THE HUMIDITY DROPPED, ALLEVIATING SOME
OF THE EXCESSIVENESS TO THE HEAT. 

MONDAY IS EXPECTED TO BE THE HOTTEST DAY FOR THIS HEAT WAVE AS
TEMPERATURES WILL PEAK IN THE UPPER 90S. HUMIDITY WILL ALSO BE
HIGHER THAN TODAY CAUSING THE HEAT INDEX TO INCREASE TO 100 TO
105. TUESDAY WILL SEE HIGH TEMPERATURES IN THE MIDDLE 90S,
HOWEVER, THE HUMIDITY IS EXPECTED TO REMAIN HIGH OR BE A BIT
HIGHER THAN ON MONDAY CAUSING THE HEAT INDEX TO AGAIN REACH 100 TO
105.

WEDNESDAY IS ALSO EXPECTED TO BE QUITE HUMID, BUT THE HIGH
TEMPERATURES SHOULD ONLY REACH THE LOWER 90S DUE TO MORE CLOUD
COVER AND THE POSSIBILITY OF THUNDERSTORMS. STUDIES HAVE SHOWN
THAT THE LONGER EXCESSIVE HEAT LASTS, THE MORE IT CAN BE LIFE
THREATENING, AND THE DANGER FROM THE EXCESSIVE HEAT COULD EXTEND
INTO WEDNESDAY.

RELIEF FROM THE HEAT AND HUMIDITY SHOULD ARRIVE IN THE FORM OF A
COLD FRONT ON THURSDAY.

HEAT INDEX VALUES OVER 100 DEGREES CAN CREATE A SITUATION IN
WHICH HEAT ILLNESSES ARE POSSIBLE...ESPECIALLY IF THIS OCCURS
OVER A NUMBER OF DAYS. ADDITIONALLY...OVERNIGHT LOW TEMPERATURES
WILL REMAIN QUITE WARM. THE LOW TEMPERATURES ON MONDAY NIGHT WILL
ONLY DROP INTO THE 70S, HOWEVER, MOST OF THE NIGHT WILL SEE
TEMPERATURES ABOUT 80, ESPECIALLY IN CENTER CITY PHILADELPHIA.

AN EXCESSIVE HEAT WARNING MEANS THAT A PROLONGED PERIOD OF
DANGEROUSLY HOT TEMPERATURES WILL OCCUR. THE COMBINATION OF HOT
TEMPERATURES AND HIGH HUMIDITY WILL COMBINE TO CREATE A DANGEROUS
SITUATION IN WHICH HEAT ILLNESSES ARE LIKELY. DRINK PLENTY OF
FLUIDS...STAY IN AN AIR-CONDITIONED ROOM...STAY OUT OF THE
SUN...AND CHECK UP ON RELATIVES AND NEIGHBORS. ALSO, NEVER LEAVE
ANY PERSON OR ANIMAL UNATTENDED IN A VEHICLE FOR ANY LENGTH OF
TIME.
