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. Some brief heavy downpours also fell during the afternoon and early evening of the 16th. The heavy rain caused small stream and poor drainage flooding in the county, but no serious injuries were reported. Storm totals included 4.40 inches in Verga, 4.14 inches in West Deptford and 2.69 inches in Monroeville. 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.
