DC area hit with weather alert as highs could top 100

Sweltering heat is making its return to the D.C. region Wednesday with highs expected to tick above 100.

Wednesday is slated to be the hottest day this week, kicking off a heat wave that could last until the weekend.

“With the humidity, feels-like temperatures will near 105 both today and tomorrow,” 791欧美激情 First Alert Meteorologist Eileen Whelan said.

The National Weather Service issued a heat advisory for the D.C. area from 11 a.m. to 8 p.m. on Wednesday as heat index values will be 105 to 109 degrees.

There is also a code orange air quality alert in effect for ground level ozone with some wildfire smoke in the upper levels of the atmosphere, according to Whelan.

“That big ridge of high pressure that’s bringing us the heat is also transporting some of that wildfire smoke to the upper levels of the atmosphere, so creating kind of that milky-looking sky,” she said.

Overnight temperatures won’t provide much relief.

Highs will once again be around 100 on Thursday.

Friday will be hot and humid, but not as extreme as the prior days. Temperatures are expected to be in the mid to upper 90s.

DC region responses to the incoming heat

As a result of the extremely hot weather, local officials are responding to the danger with caution.

In the District, Mayor Muriel Bowser announced that the city will be under an extreme heat alert for Wednesday, Thursday, Friday and Saturday. It’s recommended to avoid arduous activity outdoors from 11 a.m. to 4 p.m.

In Virginia, Fairfax County Public Schools is cancelling all outdoor activities, such as recess and extracurricular activities from 11 a.m. to 8 p.m. Wednesday.

To stay safe during the heat, it’s strongly recommended that you drink a lot of water to keep yourself hydrated, wear light clothing and stay indoors as much as possible because being outdoors in the heat could lead to heat stroke.

The CDC recommends not drinking more than 1 and a half quarts each hour because you could lose the amount of salt in your blood that could lead to a medical emergency.
