Summer weather is officially on the way, bringing the D.C. region its first heat wave of the season.
Fresh off multiple days of severe storms, Fairfax County is expected to see searing temperatures starting this Sunday (June 22), according to county officials.
The National Weather Service has “high confidence” that the daily heat index — which accounts for both the temperature and humidity — could reach as high as 110 degrees through the end of next week.
If the NWS issues an advisory, the county will activate its heat plan, which allows libraries, community centers and other public facilities to serve as cooling centers where people can find supplies like bottled water and sunscreen.
Fairfax County officials say the impending heat wave could be even harder to manage for a variety of reasons.
- We’re not used to it yet. Because there’s been relatively little hot weather so far this year, many people are not yet acclimated to such sweltering temperatures. Your body hasn’t had time to adjust to extreme heat.
- It’s going to last. The predicted heat wave that will last about five to seven days in D.C. means your body won’t get a chance to recover between hot days.
- Nights won’t cool down. Nighttime temperatures will offer little relief, with lows dipping only into the 70s or even near 80 in urban areas. This prevents your body from cooling down overnight.
- Record-breaking humidity. It’s been around other parts of the country and now it’s heading our way.
Those considered to be most at risk from the conditions include the elderly and young children, as well as anybody who is outside for prolonged periods of time.
Residents are urged to keep an eye out for heat-related illnesses, with symptoms including muscle cramps, nausea, a fast pulse and more.
“This heat wave is serious and potentially dangerous,” county officials said. “The combination of high temperatures, extreme humidity, and multiple days of heat creates perfect conditions for heat-related illness.”
To combat the high temperatures, residents are encouraged to drink plenty of water and stay inside for the hottest parts of the day, which is generally considered to be from 10 a.m. to 6 p.m.
