Four of those who died were in New York City, while the other two were in New Jersey, according to NBC.

Last night, New York City suffered its wettest hour on record, with more than 80mm of rain falling in Central Park in the space of 60 minutes.

That eclipsed the previous record of 49mm that was set in the aftermath of Tropical Storm Henri just last month.

Parts of New Jersey and Connecticut are also under a flash flood warning.

The casualties include a 19-year-old who was found dead at a flooded block of flats in Rockville, New Jersey, where water had almost reached the ceilings of the basement.

The New York City Fire Department said it responded to a report of flooding in Queens shortly after 11pm and one person taken from the building was pronounced dead.

A second person was taken to hospital.

Another victim in Passaic, New Jersey, was found dead in a vehicle that went underwear near the Prassaic River, according to the city’s mayor.

The National Weather Service’s New York City Twitter account said: “This emergency was issued due to the ongoing life threatening flash flooding.

The heaviest rain has pushed east of the Flash Flood Emergency area, with more moderate rainfall the next few hours.”

Flights in and out of Newark airport have been cancelled, and there was widespread disruption on railways.

Newark Liberty Airport’s Twitter account said: “We’re experiencing severe flooding due to tonight’s storm.

“All flight activity is currently suspended and travellers are strongly advised to contact their airline for the latest flight and service resumption information.

“Passengers are being diverted from ground-level flooded areas.”

Announcing a state of emergency, New York City mayor Bill de Blasio said: “I’m declaring a state of emergency in New York City tonight.

“We’re enduring a historic weather event tonight with record-breaking rain across the city, brutal flooding and dangerous conditions on our roads.

“Please stay off the streets tonight and let our first responders and emergency services get their work done.

“If you’re thinking of going outside, don’t. Stay off the subways. Stay off the roads. Don’t drive into these heavy waters.

“Stay inside.”

New York State’s governor Kathy Hochul has directed state-wide agencies to prepare to respond to emergency situations.

At least one tornado hit New Jersey, with posts on social media showing houses reduced to rubble by strong winds.

When Ida made landfall in Louisiana as a hurricane at the weekend, it left the city of New Orleans without electricity and caused huge amounts of damage.

The latest wave of devastation caused by Hurricane Ida comes as the UN warned that weather disasters are striking the world four to five times more often and causing seven times more damage than in the 1970s.
