The scorching temperatures are a concern for firefighters battling blazes that have destroyed several homes and have erupted near both rural and urban foothill neighborhoods, driving through tinder-dry brush.
In addition to the possibility of heat stroke and other hot-weather illnesses, health officers were concerned that people will pack beaches, lakes and other recreation areas without following mask and social distancing orders – a major concern in a state that has seen more than 590,000 coronavirus cases and nearly 11,000 deaths.
Excessive heat warnings and watches and heat advisories are in effect for the West Coast, Intermountain West, and the southern Plains, where record high minimum and maximum temperatures will be widespread, the Weather Service said.
In the Southwest, this summer has already gone down as the hottest on record in Phoenix with the city setting a new record for the most days with a temperature at or above 110 degrees, AccuWeather reported. The city will see highs above 110 degrees for at least the next week, the Weather Service said.
Even the normally mild Northwest will see extreme heat, as Seattle could approach a daily record of 98 degrees on Sunday, according to AccuWeather.
“Avoid strenuous activities, wear light clothing, drink plenty of fluids [and] never leave people or pets in a closed car,” the Weather Service office in Pendleton, Oregon, warned residents.
Dangerous heat is also persisting across the southern Plains, primarily across Texas and Oklahoma.
