What's Happening

New York City officials are warning of possible severe flash flooding Thursday afternoon and evening, with up to 5 inches of rain expected in some areas during the evening commute. The National Weather Service (NWS) has issued a Flood Watch for the New York City region, including parts of New Jersey and Long Island, starting 2 p.m. Thursday through 8 a.m. Friday.

Rainfall Forecast

The NWS predicts 1.5 to 3 inches of rainfall across the city through Friday afternoon.
Isolated areas may receive up to 5 inches, mostly within a 3 to 6-hour window on Thursday.
The heaviest rainfall is expected from Thursday afternoon until midnight.

Urgent Travel and Safety Advisories

New York City Emergency Management is urging residents to avoid non-essential travel and prepare for fast-developing flood conditions.

“Most of this rain could fall in as little as 3 to 6 hours,” the NWS alert noted, emphasizing the speed and volume of incoming precipitation.

Zach Iscol, Commissioner of NYC Emergency Management, urged residents to remain alert and ready:

“Every New Yorker should always be prepared for dangerous weather. Make a plan now, stay alert to changing conditions, and be ready to move quickly at the first sign of rising water.”

At-Risk Areas

People living in basement apartments or low-lying areas are at particular risk.
Those in frequently flooded homes are advised to prepare to evacuate if necessary.

City Response

Mayor Eric Adams emphasized the seriousness of flash flooding:

“Flash flooding is one of the most dangerous hazards we face in New York City because it can happen quickly and without warning.”

He added that city emergency teams are fully mobilized and urged residents to take personal precautions:

Sign up for Notify NYC, the city’s emergency alert system.
Know the exits and evacuation routes, especially if living in below-grade housing.
Prepare to act fast before conditions become life-threatening.

Regional Impact

The storm system is expected to affect not only New York City but also:

New Jersey metro areas
Parts of Long Island

These areas are also under the same flood watch and are likely to experience similar hazardous conditions.

Safety Recommendations

City officials are advising the following immediate steps:

Avoid driving during heavy rain or through flooded roadways.
Move vehicles to higher ground, especially in flood-prone neighborhoods.
Charge mobile devices in case of power outages.
Secure belongings in basements and lower levels.
Check on neighbors, especially elderly or disabled residents.

Flooding Risks in NYC

New York City has seen a growing number of flash flood incidents in recent years due to heavier rainfall events linked to climate variability. Basement apartments, common in outer boroughs like Queens and Brooklyn, are especially vulnerable.

Emergency officials reiterated the importance of proactive measures. Iscol emphasized:

“This storm system could bring intense rainfall rates and amounts in a very short period of time.”
