US Plans Major Flash Flood Response as Severe Storms Threaten New York City
New York City has activated its emergency response plan as a powerful storm system is expected to bring torrential rain, severe thunderstorms, and dangerous flash flooding from Sunday evening through Monday night.
Mayor Zohran Mamdani urged residents to take the weather threat seriously, saying city agencies have been working to prepare for the storm by clearing storm drains, inspecting flood-prone neighborhoods, and contacting residents living in basement and ground-floor apartments, which face the greatest flood risk.
The National Weather Service has issued a Flood Watch through 6 a.m. Tuesday, forecasting 2 to 3 inches of rainfall across much of the city. Some neighborhoods could receive as much as 6 inches of rain if thunderstorms repeatedly move over the same areas.
Meteorologists warned that rainfall rates could reach 2 to 3 inches per hour during the heaviest storms, creating conditions for rapid and potentially life-threatening flash flooding. The greatest threat is expected between 4 a.m. and 10 a.m. Monday, likely causing significant disruptions to the morning commute.
City officials said the heavy rainfall could overwhelm drainage systems, flooding streets, highways, underpasses, and other low-lying areas. Strong winds may also bring down trees and power lines.
Under the city’s Flash Flood Emergency Plan, New York City Emergency Management, along with sanitation, transportation, and environmental agencies, has deployed emergency crews across the five boroughs. The New York Police Department has also positioned tow trucks and emergency response teams to remove stranded vehicles and clear storm-related debris.
Emergency Management Commissioner Christina Farrell warned that flash flooding can develop quickly with little warning and encouraged residents to prepare for rapidly changing conditions throughout Monday.
Officials advised New Yorkers to avoid unnecessary travel during heavy rain, never drive or walk through floodwaters, and use public transportation whenever possible. Residents living in basement or ground-floor homes were urged to have an evacuation plan in place in case water begins to rise.
Authorities also encouraged residents to secure outdoor furniture and other loose objects that could become hazardous during strong winds. Anyone facing an immediate emergency should call 911, while non-emergency issues such as blocked storm drains or fallen trees should be reported through 311.
Officials said emergency crews will remain on alert throughout the storm and urged residents to continue monitoring official weather updates as conditions develop.
