A rescue operation was ongoing Tuesday, and it was unclear how many people may still be trapped from the collapse during heavy rain and thunderstorms.

 Mary Mac’s Tea Room on Ponce de Leon Avenue is working to reopen “as quickly as possible” after heavy rain caused a partial collapse of the restaurant’s roof on Wednesday morning.

The roof of Mary Mac’s Tea Room partially collapsed overnight prompting a temporary closure of the famed Southern eatery.

Heavy rain spawned extreme flooding in New York's Hudson Valley that killed at least one person and forced road closures as much of the rest of the Northeast U.S. began bracing for heavy rainfall.

At least 21 people died in floods in Tennessee over the weekend. Such dangerous flash flooding is a hallmark of climate change.
