New York City: State of emergency over flash flooding

A state of emergency has been declared in New York City as strong storms have brought flash flooding.

Many of the city's subway systems, streets and highways have flooded, while at least one terminal at LaGuardia Airport closed on Friday.

Up to five inches of rain fell in some areas overnight, and as much as seven inches more is due, New York governor Kathy Hochul said.

"This is a dangerous, life-threatening storm," Ms Hochul added.

She also warned people on X, formerly known as Twitter, to stay safe in New York City, Long Island, and the Hudson Valley due to extreme rainfall throughout the region.
