The strong southeast onshore flow on the 16th combined with the already high astronomical tides associated with the full moon to produce minor to moderate tidal flooding along the New Jersey oceanic coast and moderate to severe flooding in Delaware Bay in Cape May and Cumberland Counties. Tidal flooding departures increased farther up both Delaware and Raritan Bays as the high tide cycle coincided closer to the strongest winds. In addition, the funneling effect of southeast winds up the Delaware Bay contributed to increasing tidal departures. The high tide at Reedy Point (New Castle County Delaware) established an all-time record high.
In Cumberland County, the tidal flooding was described as the worst in 10 to 20 years. Maurice River, Commerical and Downe Townships were hardest hit. Many people either became trapped in their homes or vehicles. One woman was injured. Flooding was reported at Gandy's Beach and Money Island (Downe Township),  Port Norris in Commercial Township and along the Maurice River between Commerical and Maurice River Township.
In Downe Township, in Gandy beach, a woman suffered a cut after a wave struck her home and broke a window. Every homeowner on Cove Road had bulkhead damage and there was a 75 to 100 foot bulkhead breach on North Cove Road. Access was cut off to about 12 to 15 homes on South Cove Road after roadway damage. The road was reopened on the 17th. In Fortescue, a one mile stretch of the roadway was covered with up to four feet of water. In Commerical Township, the tide backed up the Maurice River. The State Police station on Ogden Avenue was flooded. The tide washed out the docks and destroyed a parking lot. Shell Pile Road was rendered impassable. A forty foot long dike within the township was badly damaged. Farther up the Maurice River, flooding occurred along Mauricetown Road in Mauricetown.

The high tide at Reedy Point (New Castle County) reached 9.26 feet above mean lower low water. This was the highest tide on record. Severe flooding starts at 9.2 feet above mean lower low water. Farther down Delaware Bay at Bivalve in Cumberland County, the high tide reached 8.55 feet above mean lower low water. There is no established threshold for flood categories at this site. At the Cape May Ferry Terminal, the high tide reached 7.72 feet above mean lower low water. Moderate tidal flooding starts at 7.7 feet above mean lower low water. Along the ocean side, the high tide reached 7.07 feet above mean lower low water at Cape May Harbor (Cape May County) and 6.89 feet above mean lower low water at Atlantic City (Atlantic County). Both were in the minor tidal flooding category.  Moderate tidal flooding occurred around Raritan Bay and in Monmouth County.  At Sandy Hook, the high tide reached 8.02 feet above mean lower low water. Moderate tidal flooding starts at 7.7 feet above mean lower low water. The high tide at South Amboy (Middlesex County) reached 8.99 feet above mean lower low water.
