    Heavy Rain, Severe Threat for I-95 Corridor

    "The steadiest rain will pour down heavily at times, triggering flash flooding."

    Following a beautiful stretch of weather in the Northeast, days of dreary weather are in store for the region.

    The same system that ignited deadly severe weather and flooding to the Midwest Saturday will be the culprit.

    Heavy rain will continue to fall across the Northeast into tonight, with a possibility for severe weather from Philadelphia southward to South Carolina.

    The robust cloud cover during the early part of the day has limited the amount of instability in the atmosphere north of the Mason/Dixon line, meaning severe storms will not be widespread that far north. Nonetheless, any storm that does become severe may produce damaging wind gusts and hail. The severe weather threat will wind down later at night but the heavy rain will continue farther north.


    The heavy rain currently inundating the mid-Atlantic coast will spread across New England tonight through Monday as the area of low pressure strengthens slightly as it moves northeastward up the coast.

    By the time the rain is all said and done, many areas will have picked up several inches of rain, with localized amounts greater than 6 inches possible.

    Some areas across the mid-Atlantic have already experienced greater than a half of foot of rainfall so far. New York (JFK) Airport, N.Y. has already received nearly 7.5 inches of rainfall as of Sunday afternoon. This rainfall amount combined with 1.22 inches for the previous 13 days of the month has broken the all-time August rainfall record. The previous record was 8.30 inches set back in 1976.

    Many other locations from Bridgeport, Ct. to Philadelphia, Pa. have received over 4 inches of rainfall since midnight.

    The steadiest rain will pour down heavily at times, triggering additional flash flooding. The downpours would also reduce visibility for motorists and cause water to build up on roadways, which heightens the risk of vehicles hydroplaning.

    Some flooding continues this afternoon from eastern Maryland through New Jersey, eastern Pennsylvania, and southeastern New York.

    A vehicle was swept off the road by high water in Nelson County, Va.

    Flooding along the Monocacy Creek caused evacuations of Musikfest in Bethlehem, Pa. One tent at the festival collapsed, but no injuries were reported.

    Several homes were flooded and many road closures were reported throughout Long Island.

    Meanwhile, it is not just the rain that those at the Northeast beaches will have to endure through Monday. A stiff wind will also develop, making being outdoors even more unpleasant. In addition, winds will kick up rough seas and could lead to coastal flooding.

    It will feel more like fall at times in New England as the clouds and rain keep temperatures down and the gusty breeze makes it feel even cooler.
