As Washingtonians are experiencing dangerous levels of heat, the National Weather Service (NWS) has announced that excessive heat warning would remain in effect until 9:00 p.m. EDT on July 21.
Heat index values are around 110 “due to temperatures in the upper 90s, and dewpoints in the lower 70s,” according to the NWS. The Service noted that such high temperatures combined with humidity may cause abrupt heat stress or heat stroke.
“Excessive Heat Warning” means that a lengthy period of dangerously high temperatures will take place. The NWS is recommending D.C. residents to check in on relatives and neighbors.
Those who are required to work or spend time outside are advised to take additional precautions. “When possible, reschedule strenuous activities to early morning or evening,” the warning said, adding that signs and symptoms of heat exhaustion and heat stroke should be monitored.
7/21 (3:13pm) the District’s Heat Emergency Plan will CONTINUE TO BE ACTIVATED until 9:00am on Tuesday, July 23.
