Flash flooding brought on by heavy rains prompted road closures, water rescues and commuter rail problems across the tristate area Sunday.
The National Weather Service said the hardest-hit areas appeared to be northern New Jersey, parts of New York’s Westchester County and a swath of coastal Connecticut along Interstate 95. The service issued flash flood warnings across the region for much of the morning Sunday as rain fell at a rate of 1 to 2 inches (2.5 to 5 centimeters) an hour in places.
