Two men died during a record-breaking rainfall that drenched the New York City metro area Thursday afternoon — a 39-year-old man found unconscious and unresponsive in a flooded basement in Brooklyn, and a 43-year-old man who died in a flooded basement boiler room in Manhattan, police said.

Firefighters suffered burns after there was an explosion as they responded to a fire involving trash and cars in the Bronx, officials said.
