Forecast Discussion:
To varying degrees, daily storm activity is expected to continue over southeast Arizona through Saturday. In addition, storm activity is anticipated to expand westward over the Mogollon Rim and into Yavapai County as the week progresses. Thus, the potential for outflows affecting West Pinal County will continue. But, it is too early to know if the outflows Wednesday through Saturday will be primarily from the northeast or from the south/southeast; the latter being more conducive to dense blowing dust. The combination of typical morning activities, such as agriculture, along with varying potential for blowing dust, will keep the forecasted daily average PM10 in the Moderate range but with a general downtrend. The same pattern holds true for PM2.5.
Peak 8 hour average Ozone each day is anticipated to be in the upper Good range.

Particulate Matter and Your Health - PM10 (Dust) and PM2.5 (Smoke)
People most vulnerable to the impacts of air pollution include children, older adults, adults exercising outdoors, people with heart or lung disease, and those suffering from asthma and bronchitis. Exposure to particulate matter can increase the number and severity of asthma attacks, cause or aggravate bronchitis or other lung disease, and reduce the body's ability to fight infection. Symptoms may include itchy eyes, nose and throat, wheezing, coughing, shortness of breath, chest pain and upper respiratory issues. The size of particles is directly linked to their potential for causing health problems. Small particles of concern include "fine particles" (such as those found in smoke and haze), which are 2.5 microns or less in size; and "coarse particles" (such as those found in wind-blown dust), which have diameters between 2.5 and 10 microns. These small particles, some much smaller in diameter than a human hair, pose the greatest problems because they can get deep into your lungs, and some may even get into your bloodstream | View ADEQ Particulate Matter Fact Sheet >
- Use gas or electric instead of burning wood
- Limit the lighting of fireworks
- Ride transit, carpool or telework
- Eliminate all unnecessary driving and/or combine trips
- Avoid dirt roads
- Avoid the use of leaf blowers
- If burning wood for heat or food preparation, use dry wood (burning wet wood releases more particulate matter)
