What the National Weather Service wrote

One to two inches of rain fell in less than 1 hour in Nogales and caused flash flooding of several roads and minor damage to a couple of homes near Western Ave.

The wider storm

A slow moving upper level weather system produced periods of heavy rain across southeast Arizona July 24 and 25, especially in Pinal and Pima counties. Flash flooding occurred where soils were already saturated from heavy rains of July 22 and 23 and runoff continued to fill the Santa Cruz River downstream. Floodwaters caused considerable road damage and a levee break in Greene Wash also caused significant damage to a section of a canal in Pinal County. Before the weather system exited the area, another round of heavy rain during the afternoon and evening of July 27 caused additional flash flooding in the Tucson Metro and in Santa Cruz County.

Began near Nogales (31.3442, -110.9477).
