An upper level trough moved through northern Mexico and southern Arizona during the afternoon hours of Tuesday August 12. Showers and thunderstorms developed around noon across southeast Arizona, and eventually developed and propagated into the east valley around 4 pm. While there were some reports of wind-related damage across the metro, the primary impact was heavy rainfall and flash flooding. Atmospheric moisture was measured at 1.5 times greater than normal for mid August. Rainfall totals ranged from less than a tenth of an inch all the way to 3+ inches. The heaviest rainfall and subsequent flooding occurred near South Mountain in South Phoenix, although much of Maricopa and Pinal counties saw some degree of flooding and flowing water.
