Strong monsoon thunderstorms developed during the late evening hours across portions of southern Gila County and they affected the areas around Globe and Miami. The primary weather hazards that developed were very heavy rainfall, flash flooding, and gusty damaging winds. By 2300MST, over one inch of rain had fallen near the Pinal Fire Burn Scar and this was more than sufficient to create an episode of flash flooding from Globe south towards the scar. Heavy debris and water washed over the bridge in Upper Ice House Canyon at 2300MST and by midnight waters were rapidly rising in Pinal Creek near the Gila County RV Park in Globe. Strong gusty outflow winds also blew down trees approximately 1 mile southeast of Globe. A Flash Flood Warning was issued at 2304MST for the area between the Pinal Fire Burn Scar and Globe.
