While northwestern sections of New Jersey were being hit hard with heavy snow, the same low pressure system caused strong winds 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. The presidential disaster area declaration for this event included Cape May County.
Along tidal sections of the Delaware River, in Camden County, U.S. Route 30, Admiral Wilson Boulevard was closed in both directions. Along Raritan Bay and the ocean side, flooding and roadway closures were reported along New Jersey State Route 35 in Aberdeen, Wall and Belmar.
Strong northeast winds overspread coastal sections of Ocean, Atlantic and Cape May Counties during the late 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 also occurred with the morning high tides on the 26th, 27th, 28th and 30th. The added contribution of the onshore winds caused areas of moderate tidal flooding to occur with the morning high tide on the 29th.
Peak wind gusts included 56 mph at the Atlantic City Marina (Atlantic County), 55 mph in Barnegat (Ocean County), 54 mph in Tuckerton (Ocean County), 51 mph in Seaside Heights (Ocean County) and Ocean City (Cape May County), 49 mph in Harvey Cedars (Ocean County).  The highest tides included 7.58 feet above mean lower low water at Sandy Hook (Monmouth County), 7.29 feet above mean lower low water at Atlantic City (Atlantic County) and 7.57 feet above mean lower low water at Cape May Harbor (Cape May County). Moderate tidal flooding starts at 7.7 feet above mean lower low water at Cape May and Sandy Hook and 7.0 feet above mean lower low water at Atlantic City. Up the Delaware Bay, at Reedy Island (New Castle County, Delaware) 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. In the tidal Delaware River, in Philadelphia, the highest tide reached 8.33 feet above mean lower low water. Minor tidal flooding starts at 8.2 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 New Jersey and a high pressure system over New England. Once the low pressure system passed far enough east of New Jersey during the evening of the 29th, both the strong wind and moderate tidal flooding threat passed.
