Heavy rainfall in New York City and the surrounding region Friday morning caused flash flooding, forcing subway lines to close, delaying flights, and turning major roadways into rivers.
Up to 5 inches of rain fell overnight with several more expected during the day, New York Governor Kathy Hochul said.
Hochul declared a state of emergency and urged people to stay indoors and off the roads. The National Weather issued a “considerable” flash-flood warning for Manhattan, Brooklyn, and Queens. Warnings were also in effect for the Bronx, Staten Island, and Jersey City, N.J.
