The same low pressure system that brought snow to northern Delaware, caused strong winds in central and southern Delaware and minor to moderate coastal flooding along the Atlantic Coast and lower Delaware Bay on the 29th. Minor tidal flooding also occurred in Upper Delaware Bay and along tidal sections of the Delaware River and its tributaries.

The episode as NWS PHI wrote it up.
The same low pressure system that brought snow to northern Delaware, caused strong winds in central and southern Delaware and minor to moderate coastal flooding along the Atlantic Coast and lower Delaware Bay on the 29th. Minor tidal flooding also occurred in Upper Delaware Bay and along tidal sections of the Delaware River and its tributaries. Peak wind gusts averaged around 50 mph along the coast and caused minor power outages.
Strong northeast winds overspread coastal sections of Kent and Sussex Counties during the second half of the morning on the 29th and persisted into the early evening hours before the low pressure system moved farther offshore. Astronomical tides were already running high because of the new moon. Because the lunar perigee occurred in close proximity to the time of the new moon, the astronomical tides were among the highest of the year in late October. Minor tidal flooding occurred with the morning high tides on the 27th, 28th and 30th. The added contribution of the onshore winds caused moderate tidal flooding to occur with the morning high tide on the 29th in Sussex County. On the morning of the 29th, tidal related roadway flooding occurred on New Road in Lewes, northbound Delaware State Route 1 north of the Indian River Inlet Bridge, on Long Neck Road at the Malones Mobile Home Park and on Oak Orchard Road in Millsboro. Delaware State Route 1 was closed as a precaution. Along Delaware Bay in Sussex County between Slaughter Beach and Broadkill Beach, roadway flooding occurred on Prime Hook and Fowler Beach Roads. Prime Hook Road remained closed through the 30th.
Peak wind gusts included 50 mph in Lewes (Sussex County), 47 mph in Dover (Kent County) and 46 mph in Dewey Beach (Sussex County). The highest tides included 7.17 feet above mean lower low water in Lewes (Sussex County). Moderate tidal flooding starts at 7.0 feet above mean lower low water. Farther up the Delaware Bay, at Reedy Island (New Castle County) the highest tide reached 7.43 feet above mean lower low water. Minor tidal flooding starts at 7.2 feet above mean lower low water.
Both the strong winds and moderate tidal flooding were cause by the pressure difference between the intensifying low pressure system to the south and east of Delaware and a high pressure system over New England. Once the low pressure system passed far enough east of Delaware during the evening of the 29th, both the strong wind and moderate tidal flooding threat passed.
