States of emergency were declared by New York Governor Kathy Hochul and her acting counterpart in New Jersey, after areas faced the threat of extreme flash floods. This came after the forecast on Thursday, which included much of the Eastern Seaboard.

The National Weather Service posted flash flood warnings along parts of the Northeast urban corridor stretching from the Washington-Baltimore region north through Philadelphia, Wilmington, Delaware, and into the New York City metropolitan area.

Get out of basements: Mayor Eric Adams issues warning
Mayor Eric Adams posted a video, issuing a warning to New Yorkers as the city reeled under rains. “I’ve issued a state of emergency. The Travel Advisory and Flood Watch are in effect until 8 AM. Stay where you are if you can,” he said.
“Don’t drive. Roadways are flooding, and crews are responding,” Adams added.
He also warned those living in basement apartments to move to high ground immediately, if they had not done so already.
The Weather Service has attributed the storm threat to a cold front that was bringing a combination of unstable air mass and exceptional amounts of atmospheric moisture to the region.
