The heat index in the D.C. region is expected to push 100 degrees Tuesday afternoon, according to FOX 5's Tucker Barnes.
You can expect another hazy, hot and humid day on Wednesday as well. In fact, temperatures are expected to climb into the 90s for at least the next seven days.
Due to the extreme heat, D.C. has activated its Heat Emergency Plan. Residents are encouraged to stay in the shade when outdoors and drink plenty of water.
District residents who do not live in an air-conditioned building can cool off at a city swimming pool, cooling center, recreation facility, senior center or other air-conditioned building.
