Rain and thunderstorms are expected to impact New York City on Monday as a strong cold front moves through the region. NYCEM has activated the City’s Flash Flood Emergency Plan. Be Ready for Thunderstorms & Rainfall: nyc.gov/beready The severe weather risk remains low but not zero. There is a slight chance of isolated strong storms capable of producing damaging wind gusts Monday evening. Localized flooding is possible, especially in low lying areas, underpasses, and locations with poor drainage. Ponding on roadways may develop during heavier downpours and where storm drains are clogged. Rain may begin Sunday evening around 7 PM and continue overnight into early Monday morning. Periods of moderate rain are likely through the overnight hours and into the Monday morning commute. Conditions become more active Monday as the cold front approaches. Scattered thunderstorms are possible late Monday morning through the afternoon, with the greatest risk for stronger storms during the evening. The most active period is expected between about 6 PM Monday and 2 AM Tuesday as the cold front moves across the region. During this time, heavier downpours, gusty winds, and organized thunderstorms may develop. Rainfall totals across New York City are expected to range from about 1.0 to 1.1 inches on average, with localized amounts up to around 1.25 inches where thunderstorms develop. Most rainfall rates will remain under 0.25 inches per hour, though heavier showers could briefly produce rates near 1 inch per hour. South to southeast winds will increase through Monday, with sustained winds around 15 to 22 mph and gusts that could reach 45 to 55 mph during the evening as the front moves through. Rain and storms gradually taper early Tuesday morning. A brief rain or snow shower cannot be ruled out Tuesday morning as cooler air moves into the region. New Yorkers should allow extra travel time during periods of heavy rain, especially during the Monday evening commute. Avoid driving through flooded streets. Even shallow water can stall vehicles. Secure loose outdoor items such as patio furniture or trash bins before winds increase. If thunder is heard, move indoors and stay away from open areas. Clear debris from nearby storm drains if it is safe to do so to help reduce street flooding. Stay informed by checking the forecast and signing up for emergency alerts: nyc.gov/notifynyc
