What happened

The episode as NWS PHI wrote it up.

The new moon at perigee produced some of the highest spring tides of the year on the 7th. This combined with weak onshore flow produced pockets of minor tidal flooding during the morning high tide. This scenario was repeated during the morning high tides of the 8th and 9th as a stronger high pressure system built over the New England coastal waters and enhanced the onshore flow. The highest tides occurred during the morning high tide on the 7th. At the Cape May Ferry Terminal, the high tide on October 7th reached 7.20 feet above mean lower low water and at Sandy Hook it reached 7.17 feet above mean lower low water. Minor tidal flooding begins with levels of 6.7 feet above mean lower low water or higher.
