Rounds of showers and thunderstorms spread across parts of the Northeast on Sunday as forecasters warned that heavy downpours in some areas could cause flash flooding.
Several flash flood warnings — meaning that flooding was imminent or happening — were posted on Sunday for parts of New Jersey, New York, Connecticut and Pennsylvania, including Philadelphia.
In Connecticut, the Belltown Volunteer Fire Department said on social media it was responding “to multiple flooding issues” around Stamford.
“Most road closures are in the Glenbrook area and downtown at this time,” it said.
Rainfall of up to two inches was possible across sections of the Northeast, with locally higher totals of up to five inches expected in parts of Long Island, coastal parts of Connecticut and Rhode Island, as well as eastern Massachusetts, including Boston and southern Worcester County.
In New York City, the authorities warned of heavy rainfall that would cause flooding of small creeks and streams, urban areas, highways, streets and underpasses.
The greatest concern for flash flooding was across Long Island and coastal parts of Connecticut and Rhode Island during the middle to late morning.
The threat of flash flooding was expected to decrease by late Sunday afternoon as the heaviest showers and thunderstorms were forecast to move eastward off the coast.
