Phoenix Dust Storm: Monsoon Safety Tips and Weather Updates

Sunday night's dust storm swept across metro Phoenix, knocking out power for thousands of Salt River Project customers and delivering a preview of what forecasters say will be a highly active monsoon period. With daily storm chances persisting through this week and into next week, residents need to prepare for blowing dust, flash flooding, and the health risks that come with Arizona's summer weather pattern. This phoenix weather dust storm event underscores the importance of staying informed and safe.

Power Outages and Storm Impact

The dust storm that moved through the Valley on Sunday night caused two outages affecting about 1,500 SRP customers near Avondale Boulevard and Buckeye Road. SRP officials are investigating the cause of those outages, though a dust storm did move through the area. Estimated restoration time was around 10 p.m. Another outage affected about 1,000 SRP customers east of San Tan Valley, where weather was determined to be the cause.

Monday's monsoon storms brought more dust, high winds, and heavy rain through parts of the Valley, leaving some without power and others with damage. Severe thunderstorms tracked through the Florence and Kearny areas as of 5:30 PM, bringing 60 mph wind gusts, small hail, and heavy rain with lightning.

Rainfall Totals Across the Valley

As of 4 a.m. July 14, the Maricopa County Flood Control District reported measurable rainfall from Monday's storms across numerous locations. The highest totals include:

Monsoon Pattern and Forecast

Arizona is in a typical July monsoon pattern: thunderstorms develop over the mountains in the afternoon and track southwest into the valleys. Monday's storms were expected to end by around 10 PM in the Valley and across the state. Tuesday will start with sunny skies and temperatures in the upper 80s in the Valley, but storms will build over the mountains by 2 PM and track southwest throughout the afternoon and evening. More flash flooding is likely in the mountains, and strong winds, lightning, and blowing dust will be possible with all storms.

Looking ahead, this same pattern will repeat each day through the weekend, with the most widespread storm activity likely happening on Thursday and Friday. High temperatures will range from 104 to 108 degrees before dropping to 99 degrees by Friday, accompanied by humid conditions and dew points between 55 and 65 degrees. Temperatures will gradually fall by the end of the week, only climbing into the low 100s in the Valley, with overnight lows in the 80s.

Safety Tips for Dust Storms and Monsoon

When a dust storm hits, visibility can drop to near zero in seconds. If you are driving and encounter blowing dust, pull off the road as far as possible, turn off all lights (to prevent other drivers from following your taillights into your vehicle), and wait for conditions to improve. Do not stop in a travel lane. If you are at home, seek shelter indoors during lightning and avoid flooded areas. Dust can aggravate respiratory conditions, so consider wearing a mask if you must be outdoors during a dust storm.

Health Considerations

The fine particulate matter in dust storms can irritate the lungs and worsen conditions like asthma, COPD, and allergies. People with respiratory issues should limit outdoor exposure during dust events and keep windows and doors closed. If you have to go outside, a mask can help filter some of the larger particles.

For the latest weather conditions, check the radar and forecasts from local sources. The chance for rain throughout the week for AZ means that even if your area stays dry, storms could develop nearby with little warning.
