On Staten Island, railway services were suspended in both directions due to flooding. A flood warning was issued for the area which had recorded about 4 to 6 inches (10.2 to 15.2 centimetres) of rain, according to NYC’s emergency notification system.

At least one water rescue operation was under way in Westchester County, north of New York City.

“At this time, residents are still strongly advised to avoid all travel unless fleeing an area that is subject to flooding, or under an evacuation order,” said Carolyn Fortino, a spokesperson for the county executive.

Airports across the East Coast also faced widespread disruption. A total of 1,966 flights were cancelled and more than 10,000 were delayed.

Ground stops were issued at LaGuardia and Newark Liberty airports, while John F. Kennedy Airport warned of widespread delays.

United Airlines, which has a hub at Newark, said: “Severe weather conditions are impacting operations at Newark Liberty with a ground stop issued to manage volume and limit congestion.”
