An area of low pressure tracking along a stalled frontal boundary extending across the central Appalachians eastward through the Mid Atlantic States produced multiple waves of heavy rain over sections of central to southern New Jersey from the late evening on the 29th through the late evening on the 30th, with some showers lasting into the morning of the 31st before low pressure tracked east and away from the coast.  Run-off from waves of heavy precipitation caused some poor drainage and roadway flooding.  Some streams and small rivers also overflowed their banks on the 30th and the 31st, with some not returning below flood stage until the first couple of days into April.  Storm total rainfall measurements ranged mainly between 2 and 4 inches across central to southern New Jersey.
In addition, the combination of the heavy rain and higher than normal astronomical tides associated with the new moon caused minor tidal flooding along the northern New Jersey coast during the evening high tide cycle on the 30th.  At Sandy Hook (Monmouth County), the highest tide reached 6.88 feet above mean lower low water at 812 p.m. EDT on the 30th.  Minor tidal flooding starts at 6.7 feet above mean lower low water.
