Extreme heat due for DC area Saturday, heat index may top 100

A heat emergency continues in D.C. as temperatures are forecast to climb into the mid to upper 90s by Saturday afternoon.

The high temperatures, which with humidity may feel like 100 degrees or more at times, are expected to stick around for at least the next week.

It is forecast to be sunny Saturday with a chance of isolated showers south of the District, according to Storm Team4 meteorologist Lauryn Ricketts. While a small break in humidity is expected, humid conditions are expected to return Sunday.



Sunday’s heat index could reach 107, and near 110 on Monday.

The National Weather Service will likely issue a heat advisory for Sunday, Monday and Tuesday with heat indexes over 105 degrees during the afternoon hours, Storm Team4 meteorologist Amelia Draper said.

D.C.’s Homeland Security and Emergency Management Agency issued a heat emergency on Friday.

Keeping cool

Local utilities are getting the word out about the importance of conserving energy during hot stretches like the one the D.C. area is in.

Peggy Fox, a Dominion Energy spokeswoman, said the utility is also ready to meet the anticipated high demand.

鈥淲e spend a lot of time and resources throughout the year to inspect, maintain and upgrade our electrical systems,鈥 Fox said. 鈥淲e鈥檙e always out there.鈥

Fox said the best way for customers to conserve power is raising the thermostat.

鈥淵ou can save up to 3% on cooling costs for each degree,鈥 Fox said. 鈥淪o we advise to try the EPA鈥檚 recommended 78 degrees when you鈥檙e away from home.鈥

Other ideas include closing the blinds, cooking outside and only keeping fans on when you鈥檙e in the room.

Cooling centers during the coronavirus

, people will be offered a mask which they are required to wear for the entire time they are in the cooling site. Social distancing will be practiced, as people are directed to open seats that are marked with tape to indicate distancing requirements.
