At least 14 people have now died in New York, New Jersey and Pennsylvania following the remnants of Hurricane Ida.
Eight of the victims were in New York City, and include a two-year-old boy. Some died when they became trapped in flooded basements.
More deaths are expected in Philadelphia where officials have reported “multiple fatalities,” without giving further details.
In New Jersey, five people died in the same apartment complex in the city of Elizabeth.
Officials are asking residents to check on their neighbours as the clean-up effort gets underway.
