The extreme heat wave continues to plague parts of the country Thursday, especially in the southeastern region of the U.S.

High temperatures are expected to be near 100 and heat indexes could reach 115 degrees.

The National Weather Service is warning people across the Southeast to stay inside, wear cool clothes and drink plenty of water.

Some places have set up cooling shelters to keep people out of the heat.

After three children were found in hot vehicles this week, emergency responders in Raleigh, N.C. are warning people to be extra careful.

"We really encourage family members to make that extra effort whenever they're out in the community to make sure that that doesn't happen to them," said Dr. Brent Myers of the Wake County, Ga. EMS System.
