Scattered showers and thunderstorms developed during the morning hours across south central Arizona on October 9th, and due to an influx of tropical moisture from former tropical storm Simon, the storms were able to produce very heavy rainfall. Peak rain rates with the stronger thunderstorms approached 2 inches per hour, and the heavy rain led to significant flooding of roads and washes across the far eastern portion of the greater Phoenix metropolitan area, including communities such as Apache Junction and east Mesa. Flooding was reported along the Superstition Freeway in Apache Junction and this led to the issuance of an Areal Flood Warning which ran from 851MST through 1145MST.

Scattered showers and thunderstorms developed across the far eastern portion of the greater Phoenix metropolitan area during the early morning hours on October 9th, and they persisted into the middle of the morning. Due to an influx of tropical moisture from former tropical storm Simon, the storms produced very heavy rain with peak rain rates approaching 2 inches per hour. The heavy rain led to significant urban and small stream flooding across portions of east Mesa and Apache Junction, especially along the Superstition Freeway. According to a trained spotter located 1 mile southeast of Apache Junction, at 0816MST there was water 5 inches deep flooding the intersection of the Superstition Freeway US 60 and Tomahawk road in Apache Junction. Flooding was also reported along a wash extending from the intersection of Ironwood Drive and 16th Avenue to the Superstition Freeway near Meridian Avenue. As a result of the flooding, an Areal Flood Warning was issued at 0850MST and it continued through 1145MST.
