It is not only snow and rain returning to the mid-Atlantic and far-southern New England, but also coastal flooding and erosion concerns.

The coastal flooding problems will arise on Monday as a storm strengthens along the mid-Atlantic coast and allows heavy snow to spread across southeastern New Jersey and southern coastal Delaware, and AccuWeather.com Expert Senior Meteorologist Alex Sosnowski gives additional details in this news story.

Winds circulating around the storm will drive some ocean water toward the coasts of southern Delaware, New Jersey, northern Long Island, Nantucket Island, Martha's Vineyard and the northern- and eastern-facing areas of Cape Cod through Monday night.

That is especially true during the high tide cycle Monday evening from New York to Delaware and later Monday night farther east over New England. During Monday night, winds will increase as the storm strengthens. In turn, more water will be driven toward the coast for a time.

The duration of the onshore winds will be brief enough to prevent major coastal flooding and beach erosion; however, there can be minor flooding problems with water levels set to peak between 2 and 3 feet above published values. Further erosion damage is possible due to the current storm. Prior storms over the winter and autumn have caused considerable damage, much of which has not been repaired.

The risk of minor coastal flooding will continue on Cape Cod into Tuesday.

By Tuesday in New Jersey and Tuesday night along the New England coast, the storm-driven water surge will have diminished as winds turn offshore.

Tides are astronomically higher up to a couple of days ahead of Wednesday morning's full moon.
