NEW YORK (WABC) -- When it rains, it pours in New York City -- and that apparently holds true for underground as well.As showers and thunderstorms moved through the area Tuesday, a flash flood watch was in effect. Several photos and videos from viewers showed the impact of the remnants of Florence.Flooding at the L train station in the East Village at 14th Street and 1st Avenue caused commuters to get their feet a little wet.Video from Penn Station showed what appeared to be a waterfall of rain coming down while people waited for the next train.Local southbound C and E trains ran on the express tracks during the downpour.Drivers in Queens and Hoboken were also met with flooded streets: Rain amounts of 1 to 2 inches will occur across much of Pennsylvania, New Jersey, the New York City area and southern and central New England, while higher amounts of 2 to 4 inches can occur over western and central Pennsylvania, also prompting concerns for flash flooding.The remnants of Florence will merge with another system pushing through the Northeast and mid-Atlantic with a cold front.In addition to the rain, expect high rip currents along the New York City, Long Island and New Jersey beaches.----------
