September 12, 2026 · wweather1 editorial · 2 min read

The National Weather Service in Upton, New York, has issued a Flood Watch for parts of northeast New Jersey and southeast New York effective Sunday morning through midday. Heavy downpours and thunderstorms are expected to create localized flooding risks.

The National Weather Service issued the alert on September 12 at 5:44 PM EDT. The watch period begins at 4:00 AM EDT on Sunday, September 13, and extends until 12:00 PM EDT on September 13.

The coverage area in northeast New Jersey includes Eastern Bergen, Eastern Essex, Eastern Passaic, Eastern Union, Hudson, Western Bergen, Western Essex, Western Passaic, and Western Union. In southeast New York, the watch covers the Bronx, Kings (Brooklyn), New York (Manhattan), Northern Queens, Richmond (Staten Island), Southern Queens, and Southern Westchester.
