New York City is preparing for significant rainfall and flash flooding on Monday, with the National Weather Service predicting multiple rounds of thunderstorms and torrential downpours. The storms are expected to bring up to two inches of rain per hour, potentially inundating low-lying neighborhoods and causing substantial transportation disruptions.
The most severe impacts are anticipated during Monday's morning commute, between 4 a.m. and 10 a.m., though scattered thunderstorms could continue into the evening. A flood watch will remain in effect until Tuesday morning.
Mayor Zohran Mamdani has activated the City’s Flash Flood Emergency Plan, mobilizing agencies to prepare for the severe weather. The Department of Environmental Protection, the Department of Sanitation, and the Department of Transportation have been inspecting and clearing catch basins in flood-prone areas. Specialized emergency teams and equipment are also positioned throughout the city for rapid deployment.
Mamdani urged New Yorkers to heed the warnings, limit travel during peak rainfall, and seek shelter indoors if conditions worsen. "Now it's time for all of us to do our part. Limit travel if you can, plan for delays, and take these warnings seriously," he stated. He also advised residents to check on neighbors, particularly those in basement apartments, to ensure they have safety plans in place.
The anticipated storms follow a recent heat wave that brought scorching temperatures to the metropolitan area. Central Park recorded a high of 100 degrees Fahrenheit on Thursday, the first time the location has reached triple digits since July 18, 2012. Intense thunderstorms also occurred over the Fourth of July weekend.
