Episode narrativeepisode_narrativeScattered thunderstorms continued to develop across the central and southeast portions of the greater Phoenix metropolitan area during the very early morning hours on August 10th. Very heavy rainfall was associated with these storms, slightly unusual given the time of day. Peak rain rates were in excess of 2 inches per hours at times and the intense rainfall led to episodes of flash flooding and flooding, affecting communities such as Tempe, Mesa, Chandler and Queen Creek. From midnight into the very early morning, there were numerous reports from local law enforcement and department of highways personnel indicating the presence of flash flooding. Numerous roads were closed due to the flash flooding; washes were flowing and running over roads and urban street flooding was observed. No accident or injuries were reported due to the flash flooding.

According to a trained spotter located 2 miles northwest of Mesa, at 0004MST heavy rain led to street flooding near the intersection of the Rio Salado Parkway and Alma School Road. He indicated that the water was exceeding some of the curbs. A Flash Flood Warning was in effect at the time and remained in effect through 0300MST, however flash flooding was not reported at this location.
