A nearly stationary front helped trigger showers and thunderstorms with heavy rain that resulted in flash flooding in southwestern New Jersey during the afternoon of the 30th. Doppler Radar storm total estimates reached two to three inches from Evesham Township through sections of Camden, Gloucester and Salem Counties.  Extremely wet antecedent conditions made it easier for flash flooding to occur. On  a statewide average, June 2013 was the wettest June on record dating back to 1895. The statewide average total of 9.55 inches was 5.55 inches wetter than average. On a county weighted average,  June rainfall totals ranged from 7.7 inches in Cape May County to 11.9 inches in Camden and Gloucester Counties. In Atlantic City, it was the third wettest June on record (7.53 inches). The June precipitation total in Trenton was 10.16 inches.
