At least two people were killed Thursday after record-breaking rainfall inundated New York City, flooding streets, subways, and basements across multiple boroughs, authorities confirmed.

The New York Police Department said both victims were found in flooded basements, as emergency crews responded to dozens of calls for water rescues amid torrential downpours.

According to ABC News, one victim — a 39-year-old man — was discovered unconscious and unresponsive inside a submerged basement apartment in Brooklyn. Members of the FDNY Scuba Team recovered his body before he was pronounced dead at a nearby hospital.

In a separate incident in Washington Heights, Manhattan, police said a 43-year-old man was found dead in a flooded boiler room. Both cases remain under investigation.

The city’s emergency management office said rainfall totals shattered century-old records. The National Weather Service (NWS) reported 1.8 inches of rain in Central Park, surpassing a 1917 record, while LaGuardia Airport recorded 1.97 inches, breaking a 1955 mark.

Flash flood warnings were issued Thursday evening for Brooklyn, Queens, and the Bronx, as heavy rain swamped low-lying neighborhoods and overwhelmed the city’s aging drainage systems.

Videos shared online showed cars submerged up to their windows, water cascading into subway stations, and commuters wading through waist-deep floodwaters.

The flooding also caused significant travel disruptions. More than 1,000 flights were canceled nationwide, most across the Northeast, according to FlightAware. Both John F. Kennedy International Airport and LaGuardia Airport experienced extended ground delays due to flooding and high winds.

Public transportation faced severe delays as MTA crews pumped water from several subway lines, particularly in Brooklyn and Queens, where stations briefly became impassable.

City officials warned residents to avoid unnecessary travel and to steer clear of flooded roadways and basements.

“This kind of rainfall can turn deadly in minutes,” a spokesperson for NYC Emergency Management said. “We’re urging everyone to take extreme caution and stay informed.”

The extreme weather marks yet another reminder of New York City’s vulnerability to flash flooding amid increasingly erratic climate patterns — just weeks after a similar deluge crippled parts of the city’s transportation network.
