Several subway stations were flooded in New York on Thursday (8), blocking major roads, where the arrival of Hurricane Elsa threatened new floods this Friday (9).

The U.S. Meteorological Agency NWS reported 50 to 100 millimeters of water in New York and its environs Thursday afternoon, causing flooding in some areas.

Subway users posted videos of some of the stations flooded on Twitter. In one, people were seen in the water up to the waist, trying to cross the dark pool and reach the platforms.

Sarah Feinberg, acting head of the MTA, the New York Public Transport Authority, told a news conference Thursday night that “Lines 1 and A have been registered … and many stations have been flooded.”

Mainly some axles in the Bronx were temporarily closed, causing traffic problems when leaving work.

The NWS has warned of fresh flooding until this Friday morning, with Hurricane Elsa following heavy rains in the northeastern United States. The storm has already passed through the Caribbean and Florida.
