Dust Storm Warning Issued for Phoenix Metro Amid Monsoon Activity
• On the evening of July 12, 2026, the National Weather Service (NWS) issued a Dust Storm Warning for Maricopa County, including the Phoenix metro area, as a large plume of dust moved along State Route
• The storm, traveling northwest at 30 mph, brought near-zero visibility and wind gusts exceeding 40 mph. The warning remained in effect until 8:45 p.m. The storm was part of broader monsoon activity, with thunderstorms developing over higher terrain and southern Arizona. These storms carried the potential for damaging winds and dense blowing dust, particularly in lower-elevation areas. A ground stoppage was also issued at Sky Harbor International Airport, delaying nearly 400 flights. The NWS advised residents to prepare for additional storm activity throughout the week.
Impact & Risks
The dust storm created hazardous travel conditions, particularly along State Route 202 and other major highways. Visibility dropped to near zero, and wind gusts over 40 mph posed risks to drivers and high-profile vehicles. The storm also disrupted air travel, with nearly 400 flights delayed at Sky Harbor International Airport. Thunderstorms accompanying the dust storm increased the likelihood of localized flooding and property damage. Residents in lower-elevation areas faced a 30-50% chance of storm impacts, including heavy rain and strong winds.
