Published September 19, 2026 7:23 AM EDT

An approaching low-pressure system is set to deliver widespread rain and a risk of localized flooding to the New York City area on Sunday.

What we know:

Widespread rain is forecast to move into the region, accompanied by a period of heavy downpours and embedded thunderstorms from Sunday afternoon into Sunday night.

Rainfall totals 

The National Weather Service anticipates rainfall totals ranging from 1 to 1.5 inches across much of the area, though localized spots could see higher amounts. A forecast map indicates areas including New York City, Newark, and parts of Long Island could see 0.5 to 1 inch of rain, while areas further north and east, including the lower Hudson Valley and Connecticut, are slated for 1 to 1.5 inches.

Flooding threats

Minor flooding in urban and poor drainage areas remains a likely threat for some locations. Forecasters also warn of possible minor flooding along quick-responding small rivers and streams. The region remains under a marginal risk for excessive rainfall, meaning isolated instances of flash flooding could occur in areas that experience repetitive heavy downpours or thunderstorms.
