New York City Mayor Eric Adams and New York Gov. Kathy Hochul both announced a state of emergency on Friday after a deluge of rain caused wild flash flooding across the tri-state area. Parts of New York City were totally submerged, including subway stations, expressways, and even buses. Some areas of the city were hit with more than 3 inches of rainfall in just an hour, and most of the tri-state region was told to expect between 1 and 8 inches before the storm passes. Footage shared online showed neighborhoods submerged in waist-deep water, with knee-deep water seeping into buses and major roadways brought to a standstill as cars almost floated away. Flash flood warnings were issued for most of the city and surrounding counties in New Jersey, the Hudson Valley, and Connecticut—much of which had already been drenched for days thanks to the remnants of Tropical Storm Ophelia.
