The National Weather Service (NWS) has issued a Flood Watch for New York City, effective from 8 a.m. on Tuesday, July 28, to 8 a.m. on Wednesday, July 29. The city is bracing for an anomalous low-pressure system that is expected to bring extended periods of showers, thunderstorms, and locally heavy rainfall. The New York City Emergency Management Department (NYCEM) is urging residents to prepare for potential localized flooding and dangerous flash flooding.
Mayor Zohran Mamdani emphasized the importance of preparedness, stating, “After a beautiful summer weekend, rain is returning to New York City. Our agencies are out preparing our infrastructure to quickly move stormwater off our streets, but everyone has a part to play in keeping themselves and their communities safe.” The city’s emergency management teams are working closely with the NWS and other agencies to monitor the situation and provide timely updates.
Forecast Details and Potential Impacts
The NWS forecast indicates that the city could receive between 2 to 5 inches of rainfall from Tuesday morning through Wednesday morning, with the heaviest rain expected in the afternoon and evening of Tuesday. This heavy rainfall could lead to localized flooding in poor drainage and low-lying areas, as well as potential scattered flooding on roadways, highways, and underpasses. The region is also under a marginal risk of severe thunderstorms, which could bring gusty winds, frequent lightning, and brief heavy downpours.
NYC Emergency Management Commissioner Christina Farrell highlighted the potential risks, stating, “Forecasters have the city at risk for excessive rainfall on Tuesday. That means there’s potential for street flooding, ponding at underpasses, and water moving into basements. New Yorkers in basement apartments should know their exits now and be ready to move to a higher floor when heavy rain begins.” The city has activated its Flash Flood Emergency Plan, which includes pre-storm actions such as targeted inspections and clearing of catch basins in flood-prone areas.
Preparedness and Safety Tips
To help residents stay safe during the severe weather, NYCEM has provided a list of preparedness actions. Before the storm, residents should sign up for alerts through Notify NYC, know their evacuation plan, secure loose outdoor items, and protect their homes by unplugging electronics or using surge protectors. It is also recommended to have a Go Bag ready with essentials such as medications, a flashlight, batteries, a portable phone charger, and important documents in waterproof bags.
During the storm, residents should call 911 if they are in immediate danger, move indoors when they hear thunder, and avoid windows, electrical equipment, and plumbing. If a Severe Thunderstorm Watch or Warning, or High Wind Watch or Warning is issued, residents should go to their safe indoor spot and stay there until the warning expires. If driving, residents should slow down, allow extra travel time, and never drive through standing water or around barricades.
After the storm, residents should stay away from downed power lines, watch out for fallen trees and branches, secure and report loose objects, and check their homes for damage. It is also important to check on neighbors, especially elderly individuals, people with disabilities, and anyone who may need extra help.
