A batch of drenching rain capable of producing isolated flash flooding will affect part of the East Coast into Tuesday.
The combination of tropical moisture and a disturbance moving along a frontal zone are responsible for the rainfall.
According to AccuWeather Hurricane Expert Dan Kottlowski, "The feature is not likely develop into a tropical system due to interaction with land and strong, disruptive winds above the surface over the next couple of days."
Instead, rounds of heavy rain and flooding downpours will creep northward from the Carolinas to coastal areas of the mid-Atlantic, before turning out to sea and avoiding much of New England. Highs will generally be in the 70s to near 80 from the Carolinas to Maine through Tuesday.
According to AccuWeather Chief Operating Officer Evan Myers, "While the worst of the rain will avoid New York City, the storm will make for nasty weather at the beach not only in the Carolinas and southeastern Virginia, but also Delmarva and southern New Jersey."
Beach communities that have been and/or will continue to be affected by the drenching rain include Myrtle Beach, South Carolina; Wrightsville Beach, North Carolina; Virginia Beach, Virginia; Ocean City, Maryland; and Atlantic City, New Jersey.
Some rain will brush New York City, Long Island and Cape Cod, Massachusetts, on Tuesday.
Within the zone of rain and in the dry air to its north and west, cool air will dominate much of the East, compared to the first week of September, when much of the region was very warm and humid.
During the period from Sunday to Monday morning, portions of northern Florida, Georgia and the Carolinas received several inches of rain with incidents of flooded streets.
Motorists traveling along U.S. Route 13, part of Interstate 95 in Virginia and North Carolina and a portion of the Garden State Parkway can expect slow travel at times due to blinding downpours and a buildup of water on the road.
The heavy rain will end from southwest to northeast Monday night over the Carolinas then move out to the east Tuesday evening farther north.
Later in the week, a storm system packing severe thunderstorms is forecast to move in from the Midwest with the potential for drenching downpours and locally severe weather along much of the East coast.
The rain and storms may impact MLB games, as well as the Thursday night NFL game at Baltimore, between the Ravens and Steelers.
