Forecast Discussion:
Full sun, light winds, and well above normal temperatures will contribute to peak 8 hour average Ozone reaching into the Unhealthy for Sensitive Groups category today. Thus, a High Pollution Advisory is in effect. Conditions are anticipated to be only slightly better Thursday with Ozone falling just shy of Advisory thresholds. Some additional improvement is anticipated Friday with better ventilation followed by substantially better improvement over the weekend with a lot more cloudiness and breezy to windy conditions (along with rainfall potential).
Daily average PM10 (dust) levels are expected to reach the low Moderate range today and Thursday driven largely by short lived periods in the morning when activities such as construction ramp up before the morning inversion dissipates. An improving trend begins Friday and continues through the weekend with improved ventilation along with the likelihood of rainfall before the weekend is over (most likely on Sunday). Daily average PM2.5 (smoke/combustion particles) will follow a similar trend.

Ozone and Your Health
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
