Heat Warning Remains in Effect


from National Weather Service
..EXCESSIVE HEAT WARNING REMAINS IN EFFECT UNTIL 10 PM PDT WEDNESDAY FOR INTERIOR PORTIONS OF SOUTHWEST WASHINGTON AND NORTHWEST OREGON...
AN EXCESSIVE HEAT WARNING REMAINS IN EFFECT UNTIL 10 PM PDT WEDNESDAY.
THE HOTTEST WEATHER OF THE SEASON IS DEVELOPING IN THE INTERIOR OF SOUTHWEST WASHINGTON AND NORTHWEST OREGON THIS AFTERNOON...AND IS EXPECTED TO CONTINUE AT LEAST THROUGH WEDNESDAY.
TEMPERATURES THIS AFTERNOON ARE ALREADY IN THE MID 90S AT ALL INTERIOR LOCATIONS. WITH A FEW MORE HOURS OF WARMING LEFT THIS AFTERNOON...WE MAY EVEN REACH 100 DEGREES TODAY. TUESDAY AND WEDNESDAY ARE EXPECTED TO BE EVEN HOTTER...WITH HIGH TEMPERATURES IN THE INTERIOR VALLEYS EXPECTED TO BE BETWEEN 100 AND 105 DEGREES. EVEN THE COAST RANGE AND CASCADES WILL BE HOT...WITH TEMPERATURES CLIMBING WELL INTO THE 90S DURING THIS HEAT WAVE.
ONLY THE IMMEDIATE COAST IS LIKELY TO ESCAPE THE BRUNT OF THE HEAT...WITH TEMPERATURES THERE LIKELY STAYING BELOW 90 DEGREES.
IN ADDITION TO THE HOT AFTERNOONS...LITTLE RELIEF FROM THE HEAT IS EXPECTED OVERNIGHT. WITH LITTLE TO NO COOLING INFLUENCE FROM THE OCEAN...AND A SOMEWHAT HUMID AIR MASS IN PLACE...NIGHTS WILL REMAIN QUITE UNCOMFORTABLE AWAY FROM THE COAST. THIS WILL ESPECIALLY BE THE CASE IN URBAN AREAS SUCH AS PORTLAND AND VANCOUVER. OVERNIGHT LOW TEMPERATURES TONIGHT AND TUESDAY NIGHT WILL GENERALLY BE IN THE 60S...BUT DOWNTOWN AREAS MAY NOT FALL BELOW THE LOWER 70S. THIS LACK OF OVERNIGHT RELIEF MAY MAKE THIS HEATWAVE PARTICULARLY DANGEROUS IN THE CITIES...ESPECIALLY FOR THOSE WITHOUT ACCESS TO AIR CONDITIONING.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
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.
