What happened
The episode as NWS PHI wrote it up.
A slow moving low pressure system moved northeast from southern Texas the morning of the 12th into southern Mississippi the morning of the 13th and into West Virginia the morning of the 14th. A second low pressure system formed near the Delmarva Peninsula during the day on the 14th and moved well offshore that night. The slow movement by the low gave most of southern New Jersey and parts of west central New Jersey about 24 hours of steady rain from noon on the 13th into the mid afternoon of the 14th. The heaviest rain (about two-thirds of the storm total) fell during the morning and early afternoon of the 14th. Storm totals averaged around an inch and a half. There was some urban and poor drainage flooding, but no other problems were reported. Storm totals included 2.48 inches in Estell Manor (Atlantic County), 1.90 inches in West Deptford (Gloucester County), 1.86 inches in Mount Laurel (Burlington County) and Verga (Gloucester County), 1.84 inches in Lumberton (Burlington County), 1.80 inches in Somerdale (Camden County), 1.76 inches in New Lisbon (Burlington County), 1.67 inches in Westampton (Burlington County), 1.53 inches in Cherry Hill (Camden County), 1.50 inches in Hamilton Square (Mercer County), 1.43 inches in Seabrook (Cumberland County), Washington's Crossing (Mercer County) and Wertsville (Hunterdon County) and 1.37 inches in Millville (Cumberland County). Storm totals in the rest of New Jersey were around an inch.
