Mass flooding in New York City is testing its infrastructure.

Roads and some subway tracks flooded just as millions of New Yorkers started their day on Friday. With waterlogged transportation systems and dangerous street conditions, Gov. Kathy Hochul declared a state of emergency across New York City.

Meteorologists predicted the city could see up to four inches of rain as the storm system moves through the tri-state area.

"Heavy rain in NYC causing flooding of streets & low-lying areas, including basements. Prepare to move to higher ground if needed as flooding may occur with little to no notice and can be life-threatening," read a tweet from the city's emergency notification center.

LaGuardia Airport was forced to close access to Terminal A and two nearby roads Friday morning because of flooding. The airport also reported flight disruptions as a result of weather conditions.

Officials have also closed FDR Drive in Manhattan because of dangerous flooding. A video circulating on social media shows parts of the major road completely under water as of late Friday morning.

More than 4 inches of rain hit Brooklyn Friday morning, CNN reports, exceeding the area's average September rainfall of 3.28 inches in just a matter of hours.
