Arizona Weather Whiplash: Rain, Wind, and Extreme Heat!
Arizona is experiencing a dramatic weather rollercoaster! Monsoon storms brought much-needed rain to the Valley, with Phoenix Sky Harbor recording its first measurable rainfall (0.04") since July 2nd. However, the 2025 monsoon season is still significantly below normal, with only 0.20" of rain received so far.
The intense thunderstorms caused flash flooding, with standing water reported on Interstate 17 in central Phoenix. The Arizona DOT even issued a warning about standing water on the Glendale Avenue off-ramp from southbound I-17.
Strong winds accompanied the storms, with Phoenix Sky Harbor clocking wind gusts near 70 mph! Over 20,000 APS and SRP customers lost power during the peak of the storm. Gold Canyon received 0.71" of rain, while Mesa saw over half an inch. Tempe got 0.16" and Ahwatukee received 0.39".
A dust cloud was observed in the southeast Valley around 6:30 p.m. A blowing dust advisory remains in effect until 9 p.m. between Phoenix and Tucson, potentially impacting travel on I-10.
Extreme Heat Warning Extended
Despite the monsoon activity, extreme heat continues to grip Arizona. An Extreme Heat Warning has been extended through Sunday for central, southern, and southwestern Arizona, as well as lower elevations of the Grand Canyon (below 4,000 feet). The Valley heat risk is classified as major to extreme, making everyone vulnerable to heat-related illnesses.
Phoenix is expected to reach highs of 110 to 114 degrees over the next few days, with overnight lows in the 90s. Residents are urged to stay hydrated, limit outdoor activities between 10 a.m. and 6 p.m., and bring pets indoors. Many popular hiking trails will be closed during the Extreme Heat Warning.
Air Quality Concerns
Adding to the weather woes, air quality is deteriorating. Ozone High Pollution Advisories are in effect through Friday, with Ozone High Pollution Watches extending through the weekend. Ozone pollution can trigger respiratory problems, especially for children, older adults, and those with pre-existing conditions. Residents are advised to limit outdoor activities during the afternoon hours.
