A pair of nor'easters caused minor to moderate tidal flooding along the ocean and  Delaware Bay from the evening high tide of the 15th into the morning high tide of the 19th. They also caused minor tidal flooding along the Delaware River from the morning high tide of the 16th through the morning high tide of the 17th. Tidal flooding extended into the inlets. In addition to the tidal flooding, heavy surf contributed to and exacerbated the erosion along the ocean and lower Delaware Bay. A few roadways were flooded and closed.
In Sussex County, sections of Delaware State Route 1 were flooded and closed from the 16th through the 18th from Dewey Beach south into Fenwick Island. The Indian River Inlet Bridge was also closed. A couple of roads were flooded and closed in Lewes and Dewey Beach. In Lewes, flooding along the Lewes and Rehoboth Canal threatened, but did not reach any homes. In Indian River Bay, River Road in Oak Orchard was flooded. In Dewey Beach, Crabbers Cove flooded the morning of the 17th.
Along the Sussex County beaches, scarping and erosion occurred. Sand fencing and dunes were damaged in Bethany Beach, South Bethany and Dewey Beach. In South Bethany, four dune crossings were closed. Waves at Bethany Beach reached as high as 9 feet.
Along the ocean and Delaware Bay, minor tidal flooding began with the afternoon high tide on the 15th. Moderate tidal flooding then occurred with the high tides on the mornings of the 16th and 18th and both high tides on the 17th. The highest tides occurred during the morning high tide on the 17th. At Breakwater Harbor (Lewes - Sussex County), the tide reached 7.37 feet above mean lower low water. Moderate tidal flooding starts at 7.0 feet above mean lower low water.  Along tidal sections of the Delaware River in New Castle County, minor tidal flooding occurred from the morning of the 16th into the morning of the 17th. The highest tides occurred during the morning high tide on the 16th. At Reedy Island, the tide reached 7.42 feet above mean lower low water. Minor tidal flooding begins at 7.20 feet above mean lower low water.
The first nor'easter moved from the Tennessee Valley on the morning of the 14th to the northern North Carolina coastal waters on the morning of the 15th and then moved rapidly northeast and by sunrise on the 16th was already southeast of Cape Cod, Massachusetts. The second nor'easter formed off the Delmarva coastal waters on the 17th and drifted very slowly east farther offshore as it intensified slowly. It was located about 250 miles east of Cape May, New Jersey during the afternoon of the 18th and then accelerated to the northeast and passed through Nova Scotia on the morning of the 19th. As these nor'easters formed and moved offshore, a high pressure system remained over nearby Canada and northern New England; both combined to maintain the onshore flow.
