NEW YORK CITY / NEW JERSEY — A powerful storm system slammed into the U.S. East Coast on Thursday, prompting state of emergency declarations in both New York City and New Jersey amid dangerous flash flooding and widespread chaos.

The National Weather Service issued urgent flash flood warnings across the Northeast corridor, stretching from Washington D.C. and Baltimore through Philadelphia, Wilmington, and into the heart of the New York metropolitan area. Torrents of rain overwhelmed city drainage systems, flooding highways, train stations, and neighborhoods.

Governor declarations urged residents to stay off the roads and avoid low-lying areas as emergency services scrambled to rescue stranded motorists and respond to flooded homes and businesses.

“This is a life-threatening weather event,” warned emergency officials, emphasizing the need for immediate caution and preparedness. Flights were delayed, subway lines suspended, and entire communities brought to a standstill by the relentless downpour.

With more rain forecast, authorities are closely monitoring rivers and reservoirs for potential overflow, urging residents to remain indoors and stay informed.
