… HEAT ADVISORY IN EFFECT FROM 2 PM THIS AFTERNOON TO 6 PM PDT THURSDAY…
THE NATIONAL WEATHER SERVICE IN SEATTLE HAS ISSUED A HEAT ADVISORY… WHICH IS IN EFFECT FROM 2 PM THIS AFTERNOON TO 6 PM PDT THURSDAY.
OFFSHORE FLOW… WARM AIR ALOFT… LONG DAYS… AND A HIGH EARLY JUNE SUN ANGLE ARE COMBINING TO PRODUCE VERY WARM CONDITIONS IN THE SEATTLE-TACOMA-EVERETT AREA. DAYTIME TEMPERATURES ON TUESDAY ROSE WELL INTO THE 80S TO AROUND 90. EXPECT TEMPERATURES THIS AFTERNOON AND THURSDAY AFTERNOON TO BE ABOUT THE SAME AS TUESDAY… NEAR RECORD LEVELS.
THE URBAN HEAT ISLAND EFFECT AND AN OFFSHORE BREEZE MOVING DOWN OFF THE CASCADES IS NOT ALLOWING TEMPERATURES TO COOL OFF MUCH AT NIGHT. LOW TEMPERATURES THIS MORNING AND AGAIN THURSDAY MORNING WILL ONLY BE AROUND 60 DEGREES.
DEWPOINT TEMPERATURES… A MEASURE OF HOW MUCH MOISTURE IS IN THE AIR… HAVE BEEN IN THE COMFORTABLE LOWER 40S. THEY WILL RISE TO THE LOWER 50S ON THURSDAY… MAKING IT FEEL A BIT MORE MUGGY AND UNCOMFORTABLE. LIGHTER BREEZES ON THURSDAY WILL ALSO MAKE IT FEEL MORE UNCOMFORTABLE.
THE EARLY JUNE WARM SPELL WILL COME TO AN ABRUPT END THURSDAY EVENING AS A STRONG MARINE PUSH ALLOWS COOL AND MOIST PACIFIC AIR TO SURGE INLAND.
PRECAUTIONARY/PREPAREDNESS ACTIONS…
A HEAT ADVISORY MEANS THAT A PERIOD OF HOT TEMPERATURES IS EXPECTED. THE COMBINATION OF HOT TEMPERATURES AND RATHER HIGH HUMIDITY CREATE A SITUATION IN WHICH HEAT ILLNESSES ARE POSSIBLE. DRINK PLENTY OF FLUIDS. STAY IN AN AIR-CONDITIONED ROOM IF POSSIBLE. STAY OUT OF THE SUN… AND CHECK UP ON RELATIVES AND NEIGHBORS.
REMEMBER THAT AREA LAKES AND RIVERS ARE STILL COLD. ESCAPING THE HEAT BY JUMPING INTO A COLD LAKE OR RIVER CAN LEAD TO DEATH BY HYPOTHERMIA OR DROWNING.
A heat advisory or warning has been issued. Now what do you do?
Before Exposure
- Stay indoors and avoid extreme temperature changes. If your home does not have air conditioning, go to a shopping mall or public library — even a few hours spent in air conditioning can help your body stay cooler when you go back into the heat.
- If air conditioning is not available, stay on the lowest floor out of the sunshine.
- Keep your electric fans running.
- Drink cool liquids often, particularly water, even if you do not feel thirsty, to help your body stay cool. Avoid alcoholic beverages, which dehydrate the body. During heavy exercise in a hot environment, drink two to four glasses (16-32 ounces) of cool fluids each hour.
- Eat small, frequent meals. Avoid foods that are high in protein, which increase metabolic heat.
- Keep pets indoors; refill their water bowls frequently.
During Exposure
- If you must go out, wear lightweight, light-colored clothing to reflect the sun’s energy.
- Slow down, avoid strenuous outdoor activity. If you must engage in strenuous activity, limit exposure during mid-day hours.
- Cover all exposed skin with a high SPF sunscreen, and wear a wide-brimmed hat to protect your face and head.
- Drink plenty of fluids.
- Never leave infants, children, or pets in a parked car.
After Exposure
- Continue drinking plenty of water.
- Never take a cool shower immediately after becoming overheated. You may cool too quickly and become ill, nauseous, or dizzy.
- Know the symptoms of heat disorders and overexposure to the sun, and be ready to give first aid treatment.
