The New York area was under a state of emergency on Thursday after the remnants of Hurricane Ida barreled into the region with furious, wind-driven rain that led to at least eight deaths, all but halted subway service and destroyed homes in New Jersey.

New York City recorded more rain on Wednesday than it normally does in a month, according to the National Weather Service, and the 3.1 inches that fell in Central Park over the course of an hour shattered a record set only last week.

“This is going down as a historic event,” said Nelson Vaz, a meteorologist at the Weather Service in New York, which issued a flash flood emergency in New York City for the first time.
