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 with the worst reported flooding near and along the shore. No serious injuries were reported. In Point Pleasant Beach, six roadways were closed including New Jersey State Route 35. New Jersey State Route 35 was also closed in Ship Bottom where the flooding was described as severe. There were several water rescues including one of an elderly woman in Ortley Beach. The heavy downpours and gusty winds knocked down some weakened trees and caused isolated power outages. The North Branch of the Metedeconk River at Lakewood reached its 7 foot flood stage at 430 p.m. EDT on the 17th, crested at 8 feet at 10 p.m. EDT on the 17th and was back within bankfull at 340 a.m. EDT on the 18th. Storm totals included 8.10 inches in Tuckerton, 3.50 inches in Manahawkin and 2.65 inches in Bayville. 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 before accelerating faster offshore.
