Heavy rainfall caused severe flooding in New York City. A low-pressure system moving through the mid-Atlantic and Northeast United States brought nearly 76 millimeters (3 inches) of rainfall to the New York region on October 30, 2025, causing flash floods. The rain was predicted to fall over a period of eight hours but instead arrived in an intense, 20-minute downpour. The deluge fell in the midst of a drought, which had left piles of fallen leaves and trash on the streets and sidewalks. The rain swept the detritus toward sewer drains, many of which became clogged. The storm left 1,500 residents without electricity, said a spokeswoman with the Emergency Management agency. Thunderstorms and low cloud ceilings caused arrival and departure delays at all three of the region’s major airports.
