The National Weather Service has issued a Flash Flood Watch for Wilton and the surrounding area, forecasting that heavy rain and flash flooding are possible Monday afternoon, July 12 into early Tuesday morning, July 13.
The Flash Flood Watch extends to all of southern Connecticut and northeast New Jersey, and most of southeast New York, including the following areas: in southern Connecticut — Fairfield, New Haven, Middlesex, and New London counties; in northeast New Jersey — Bergen, Essex, Hudson, Passaic, and Union counties; and in southeast New York — all five boroughs of New York City and Westchester, Orange, Putnam, Rockland, Nassau, and Western Suffolk counties.
As a warm front lifts into the area on Monday, scattered-to-numerous thunderstorms will develop Monday afternoon. As the front sinks back to the south Monday night, the front will continue to focus thunderstorm activity and heavy rain potential over the watch area, especially in and around the New York City Tri-State area. This rain will be falling in areas hard hit by heavy rain and flash flooding late last week.
Rainfall amounts of 2-3 inches are likely, with localized amounts over 4 inches possible.
