The remnants of Hurricane Ida proved devastatingly potent Wednesday night.
At least eight people died in New York City and New Jersey, the Associated Press reported.
The National Weather Service office in New York declared its first-ever set of flash flood emergencies in the region Wednesday night, an alert level that is reserved for “exceedingly rare situations when a severe threat to human life and catastrophic damage from a flash flood is happening or will happen soon,” according to the AP.
Between 4 and 8 inches of rain have fallen.
Train and subway stations and tracks became so flooded that the MTA suspended all service.
Communities such as Mamaroneck found themselves flooded and without power.
The NWS recorded 3.15 inches of rain in New York’s Central Park in one hour Wednesday night, far surpassing the 1.94 inches that fell in one hour during Tropical Storm Henri on the night of Aug. 21, which was believed at the time to be the most ever recorded in the park.
Earlier Wednesday, the storm blew through the mid-Atlantic states with at least two tornadoes, heavy winds and drenching rains that collapsed the roof of a U.S. Postal Service building in New Jersey.
