What happened
The episode as NWS PHI wrote it up.
The remnants of Tropical Storm Allison produced showers and thunderstorms with heavy rain during the morning of the 17th. This caused small stream and poor drainage flooding in the county. Gusty winds also knocked down weak tree limbs and wires. Both the Black Horse (U.S. Routes 40 & 322) and the White Horse (U.S. Route 30) Pikes were closed between the mainland and Atlantic City. In Ventnor, emergency service personnel were pushing vehicles from waist high water. There were other road closures in Egg Harbor and Galloway Townships. The flooding was so severe in Galloway Township, that the Absecon Estates development became an island. About 13,000 Conectiv customers lost power. Storm totals included 4.60 inches in Absecon, 4.00 inches in Margate, 3.74 inches in Estell Manor and 3.51 inches at the Atlantic City Marina. The peak wind gust at the Atlantic City Marina was 44 mph and at the International Airport it was 41 mph. The low pressure system that was the remnants of Tropical Storm Allison, was very persistent and slow moving. It moved from northeast North Carolina the afternoon of the 15th to near Norfolk the morning of the 16th to the Virginia Capes during the afternoon of the 16th and just east of Atlantic City during the morning of the 17th.
