The combination of spring tides associated with the full moon and then an onshore flow associated with a Cape Cod low pressure system caused minor to moderate tidal flooding during the first six days of June. Moderate tidal flooding occurred along Raritan Bay, coastal New Jersey and Delaware Bay during the evening  and overnight high tide cycle on the 4th. Tidal flooding nearly reached moderate levels on tidal sections of the Delaware River that night also. Minor tidal flooding occurred with the evening high tide cycles on the 1st, 2nd, 3rd, 5th and 6th and morning high tide cycle on the 5th.
On the evening of the 4th, along the Atlantic Coast, in Atlantic County, the White Horse Pike (U.S. Route 30) near Atlantic City was closed due to tidal flooding. West End Avenue in Atlantic City was flooded and closed. The Black Horse Pike (U.S. Routes 40 and 322) in West Atlantic City was also closed. Ohio Avenue in Absecon flooded.  In Cape May County, water was described as up to the floorboards of vehicles in Wildwood.  Both lanes of New Jersey State Route 147 were closed in North Wildwood.
Along the tidal Delaware River, overnight on the 4th, in Brooklawn (Camden County), the traffic circles near the Big Timber Creek flooded. The combination of heavy rain and minor tidal flooding also closed that same section of roadway overnight on the 1st as well as Kaighn Avenue just off the Airport Circle near the Cooper River. In both locations, several vehicles became stuck including one police cruiser.
The highest tides occurred with the high tide cycle that started on the 4th and reached moderate levels along the oceanfront and in Delaware Bay and nearly reached moderate levels on tidal sections of the Delaware River.  These included 7.97 feet above mean lower low water at Sandy Hook (Monmouth County), 7.50 feet above mean lower low water in Atlantic City (Atlantic County), 8.18 feet above mean lower low water in Cape May (Cape May County), 7.87 feet above mean lower low water at Reedy Island (New Castle County, Delaware) and 9.02 feet above mean lower low water in Philadelphia. The high tide at Atlantic City of 7.5 feet above mean lower low water was the highest tide since March 19, 1996 (7.6 feet above mean lower low water).
There are no official category tide levels at these other gage sites, but these were the tides that were recorded overnight on the 4th: 8.48 feet above mean lower low water in South Amboy (Middlesex County), 8.36 feet above mean lower low water in Keansburg (Monmouth County), 6.43 feet above mean lower low water in Sea Bright (Monmouth County), 4.62 feet above mean lower low water at Barnegat Light  (Ocean County), 6.66 feet above mean lower low water in Absecon (Atlantic County), 7.19 feet above mean lower low water in Sea Isle City (Cape May County), 6.07 feet above mean lower low water in Avalon (Cape May County), 7.33 feet above mean lower low water in Stone Harbor (Cape May County), 7.59 feet above mean lower low water in Cape May Harbor (Cape May County) and along the Delaware River, 10.10 feet above mean lower low water in Burlington City (Burlington County).
The moderate tidal flooding on the 4th was caused by the combination of spring tides associated with the full moon and a northeast flow around a low pressure system that formed and then meandered off of Cape Cod on the 3rd and 4th. A high pressure system kept a weaker northeast flow going on the 5th, but even that flow weakened further  the 6th and 7th. By the 7th,  spring astronomical tides were no longer occurring.
