Extremely heavy rainfall associated with the remnants of Hurricane Ida overspread northeast New Jersey during the evening of September 1 and continued through the early morning hours of September 2. Rainfall totals ranged from 5-8+ inches across much of the region, with much of that rain falling in just a few hours. The ASOS at Newark Airport recorded 8.44 inches of rain, while the ASOS at Teterboro Airport recorded 7.14 inches. A COOP observer in Harrison recorded 8.72 inches of rain. This resulted in widespread flash flooding leading to numerous road closures and water rescues in addition to extensive river flooding. Eight people died as a result of the flash flooding and one person remains missing.
