The National Weather Service (NWS) issued heat advisories for large portions of the East Coast and Midwest through most of the weekend, with temperatures in some areas predicted to reach up to 110 degrees F.

In central Florida, the NWS forecasted highs in the upper 90s F with heat indexes that could reach 105 to 110 degrees F. Similar temperatures were estimated to affect Georgia, the Carolinas and Virginia.

Extreme heat watches were also issued for eastern Nebraska, western Iowa and southern Minnesota, pointing at heat indexes of 96F on Saturday and even higher on Sunday in Minnesota. Between the weekend’s heat advisories, extreme heat watches and extreme heat warnings, more than 163 million people are under heat alerts, CBS estimated.

Extreme heat warnings were out for much of eastern North Carolina, as far inland as Raleigh, and extending into a corner of South Carolina, including Myrtle Beach, according to The Associated Press. Forecasters warned of dangerously hot conditions with temperatures approaching or exceeding 100 F in some areas on Sunday and heat indexes up to 115 F through Sunday evening.

“Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors,” the weather service advised. “Take extra precautions when outside. Wear lightweight and loose fitting clothing. Try to limit strenuous activities to early morning or evening. Take action when you see symptoms of heat exhaustion and heat stroke. Stay cool, stay hydrated, stay informed.”

The weather service said several major metropolitan areas in the Southeast — including Raleigh and Charlotte in North Carolina, Greenville-Spartanburg in South Carolina, and Atlanta in Georgia — were expected to face an extreme heat risk for several days, with minimal overnight relief. It said over 30 million people would likely be affected at the peak of the heat wave through midweek.

And an extreme heat warning was out for the St. Louis, Missouri, area through Tuesday evening, with highs around 99 F and heat indexes around 110 F forecast for Monday and Tuesday.

Parts of Iowa were hit by storms Saturday morning that dumped between 2 and 5 inches of rain in some areas and triggered flash flood warnings.
