New York City Flash Floods

Showers and storms brought torrential rains and flash floods to the New York City metro region. A severe storm on Sept. 29 pounded 7 inches of rain on the city in 24 hours.

Rainfall was reported at 2.5 inches per hour as the storm slammed the metropolitan region’s aging architecture. The storm placed 23 million people across New York, Connecticut and New Jersey under a flash flood watch on Sept. 29.

The storm shuttered the subway system and grounded planes at the regional airports, and a school in Brooklyn was evacuated due to the floods.
