An Ozone High Pollution Advisory is in effect for Maricopa County today and tomorrow.

Much of central Phoenix received rainfall last night, resulting in relatively low values of particulate matter at all of our monitors within the past few hours. Evening thunderstorms will remain possible every day going forward, with less activity expected today. Light winds and mostly sunny skies will be the trend today and tomorrow, influencing our ozone forecast with more elevated levels. By the end of the week, ventilation will improve with increased winds at the surface and just above the surface. The increased winds will lower ozone levels slightly, back into the upper Moderate AQI category.

As for PM10 (dust), outflow boundaries will remain possible throughout the forecast period, with late tomorrow night and early Friday morning the highest chance for blowing dust moving through the Phoenix area. Fortunately, areas to the south of Phoenix received decent rainfall last night, which will help stabilize soils and lower the chance for increased blowing dust from outflow boundaries.

Our hourly graphs above illustrate our ozone and blowing dust potential through the 5-day period.

We're halfway through the week!

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 ozone 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 | View Ozone Fact Sheet >

Please help reduce ozone by doing one or more of the following:

• Drive as little as possible, carpool, use public transit or telecommute
• Re-fuel your vehicle in the evening
• Avoid waiting in long drive-thru lines, if possible
• Use low-VOC (Volatile Organic Compounds) or water-based paints, stains, finishes and paint strippers - delay big painting projects
• Make sure containers of household cleaners, garage and yard chemicals, and other solvents are sealed properly to prevent vapors from evaporating into the air
