Weather Alert: DC Feels Like Dangerous 104 Degrees

Storm Team4 declared Thursday a Weather Alert Day

Blazing sun and oppressive humidity sent the heat index soaring to dangerous levels Thursday, Storm Team4 said. 

Thursday's high reached the mid-90s. With the humidity, the heat index reached 106 degrees Thursday afternoon. It was 104 in D.C. at 4 p.m.

"The heat index tells you how it feels outside in the shade," the Maryland Department of Health and Mental Hygiene says on its website. "The heat index is a measurement of how it feels when relative humidity is combined with the effects of the air temperature."

Storm Team4 declared Thursday a Weather Alert Day. 

A heat advisory went into effect for the I-95 corridor to the east at noon Thursday, Storm Team4 Chief Meteorologist Doug Kammerer said.

Strong storms are also possible Thursday evening.

With heat indices this high, you can get a sunburn in just 10 minutes, Storm Team meteorologist Sheena Parveen said.
