St. Louis, MO – The National Weather Service in St. Louis has issued an excessive heat warning through 7 p.m. Sunday.
Operation Weather Survival is running 50 cooling centers on the Missouri side of the region and 18 in Illinois.
Sandra Knepp with the St. Louis Health Department says some homeless shelters are staying open in the daytime:
"We have the Salvation Army, a lot of the senior centers they're all staying open," Knepp says. "And what we've decided to do is to keep the cooling centers open until after the heat advisory ends.
