The remnants of Hurricane Ida swept across the northeastern U.S. overnight, bringing torrential rains, flooding and even tornadoes to Pennsylvania, New Jersey, New York, Connecticut and Massachusetts. At least nine people were killed, adding to at least six reported deaths in the South, where Ida struck as a Category 4 hurricane over the weekend. The governors of New York and New Jersey declared states of emergency. Here in New York City, subway service was halted and non-emergency vehicles were banned from streets overnight amid heavy flooding. The National Weather Service said over three inches of rain fell in Central Park over just one hour Wednesday night, likely a new record, while a tornado warning was issued for Manhattan and the Bronx.
