The remnants of Tropical Storm Andrea moving up the Eastern Seaboard, from the Southeast States to the Mid Atlantic and Northeast Coasts, led to waves of heavy rain and thunderstorms from the early morning hours through the late evening on the 7th. The initial burst of heavy precipitation arrived during the early morning on the 7th as moisture surged into the Mid Atlantic Region ahead of Tropical Storm Andrea, with the center of its low pressure located near the coast of Georgia. Through the course of the day, the cyclone became post-tropical as it accelerated northeastward along the East Coast of the United States, delivering another round of heavy rain with some strong thunderstorms to the Mid Atlantic States during the late afternoon and evening of the 7th.
Doppler radar storm total estimates ranged from around 2 to 5 inches of rain for the event across New Jersey.  Run-off from waves of heavy precipitation resulted in areas of poor drainage and flash flooding, which caused some smaller rivers across southern New Jersey to overflow their banks.
