Arizona Weather Alert: Air Quality and Flood Risks Continue Through Tuesday
Arizona residents are facing a combination of poor air quality concerns and increased flooding potential as weather hazards remain active across central and southern portions of the state.
The latest alerts cover the Phoenix metropolitan area, Maricopa County, Pinal County, Tucson, Pima County, Santa Cruz County, Cochise County, and portions of Graham and Greenlee counties. While the threats vary by location, residents should remain alert to changing conditions through Tuesday.
Air Quality Alert for Maricopa County and Phoenix Metro
An Air Quality Alert is in effect for Maricopa County, including the Phoenix Metro Area, through Tuesday.
Reduced air quality can be especially concerning during periods of hot weather, stagnant air, smoke, dust, or elevated pollution levels. Residents should monitor local air-quality conditions and limit prolonged outdoor exposure when conditions deteriorate.
People who are sensitive to poor air quality should consider reducing strenuous outdoor activity and following local air-quality recommendations.
Pinal County Also Under an Air Quality Alert
An Air Quality Alert is also in effect for Pinal County.
Residents should keep an eye on air-quality readings before spending extended periods outdoors. Outdoor activities may need to be adjusted if pollution or airborne particles increase.
Flood Watches Expand Across Southern Arizona
Flooding is another major concern, particularly across areas where thunderstorms can produce heavy rainfall over a short period of time.
A Flood Watch covers portions of southern Arizona, including Western Pima County, Central Pima County, and Southeastern Pinal County.
Because monsoon thunderstorms can develop quickly, rainfall rates may increase rapidly. Areas with poor drainage, low-water crossings, washes, and normally dry channels can become hazardous when storms move across the region.
Flood Watch for Cochise, Graham and Greenlee Counties
Another Flood Watch covers Cochise County along with the valleys of Graham and Greenlee counties.
Thunderstorms capable of producing heavy rainfall could create localized flooding, particularly in low-lying areas and near washes and waterways.
Residents should avoid entering flooded roads or attempting to cross flowing water. Even shallow water can conceal damaged road surfaces or rapidly changing conditions.
Tucson Metro and Santa Cruz County Flood Watch
The Tucson Metro Area and Santa Cruz County are also under a Flood Watch.
Thunderstorms in and around the Tucson region can produce intense rainfall that quickly overwhelms drainage systems. Urban areas may experience ponding and street flooding, while washes can become dangerous with little warning.
Residents should remain alert to changing skies and weather alerts, especially if traveling during periods of thunderstorm activity.
Why Flash Flooding Can Develop So Quickly
Southern Arizona’s monsoon thunderstorms can produce intense rainfall in a relatively short amount of time. When several storms repeatedly move over the same location, rainfall can accumulate quickly.
Flooding can also occur downstream from a storm. That means dangerous water may reach an area even when heavy rain is no longer falling directly overhead.
Never drive through a flooded roadway. Turn around and find a safer route.
Phoenix and Southern Arizona Face Different Weather Threats
The current alerts highlight how weather conditions can vary significantly across Arizona.
Phoenix and Maricopa County: Air quality is the primary concern.
Pinal County: Air quality concerns are accompanied by flood potential in southeastern portions of the county.
Pima County and Tucson: Flooding and heavy rainfall are the primary concerns.
Santa Cruz County: Flooding remains a concern as thunderstorms affect southern Arizona.
Cochise, Graham and Greenlee counties: Heavy rainfall and flooding could affect valleys, washes and low-lying areas.
Arizona Residents Should Stay Weather Aware
Residents across the affected areas should continue monitoring weather conditions through Tuesday. Keep phones charged, avoid flooded roadways, and be prepared for rapidly changing conditions.
For those dealing with air-quality concerns, check current conditions before exercising or spending extended periods outdoors.
For those under a Flood Watch, remember that a watch means flooding is possible. Conditions can worsen quickly if thunderstorms become more widespread or repeatedly move over the same area.
