Arizona weather forecast: Monsoon weather affecting parts of the state
Dust storm advisory, flash flood warnings in parts of Arizona
Severe storms south of Phoenix sparked a dust storm advisory extending to Ahwatukee and Chandler, along with a flash flood warning near Casa Grande. FOX 10's Erica Horvatin has more on the impacts through the evening.
PHOENIX - Another hot day with high elevation storm chances.
What to Expect:
Wednesday was another active day of the monsoon. Several clusters of storms across Arizona produced severe weather, from flash floods to a dust storm advisory in the Valley. A flash flood warning remains in effect until 8:30 p.m. for the Black Canyon City area.
The dust storm brought low visibility and heavy dust to the east Valley, and we will continue to see breezy to gusty winds through the evening, along with a chance for an isolated shower or two.
Dust storm develops in Casa Grande
The monsoon season of 2026 has officially arrived in Arizona, bringing severe weather conditions to the region. A significant dust storm developed in Casa Grande, drastically reducing visibility for drivers down to zero following a brief period of rain, blowing winds and heavy dust.
Overnight will be quieter and warm in the Valley, with a low of 90 degrees. Expect poor air quality in the morning due to the dust.
Storms in the mountains will dissipate late this evening, and drier weather will follow.

- Purchase a battery-powered or hand-crank radio
- Discuss thunderstorm safety with members of your household. Be aware that a thunderstorm could produce flooding.

Be prepared and stay safe during the monsoon
"Most Valley residents know how quickly and furiously storms can move in and out, bringing strong winds, dust, rain, and flash flooding. These storms can cause interruptions in services, such as water, power, and gas," stated Captain Ashley Losch of the Glendale Fire Department.
GFD reminds residents of ways they can be prepared and stay safe:
- Have flashlights with extra batteries on hand.
- Have food that can be prepared without the need for cooking or refrigeration.
- Have at least one gallon of clean water for each person in the household.
- Have backup power for anyone requiring power for a medical device.
- Have backup power for cell phones that do not require charging.
- Have a first aid kit ready and accessible.
- Never drive into areas with flowing water; it takes less than 10 inches to wash a car away.
- Avoid flooded areas, such as washes.
- If waters are rising, seek higher ground.
- Do not approach downed power lines, the ground can be energized for up to 200 feet.
- Keep pets indoors during storms.
