Mostly sunny skies, warm temperatures and low humidity will provide a favorable environment for two types of pollutants (volatile organic compounds and nitrogen oxides) to react with sunlight in the air to produce ground-level ozone. Ozone will remain elevated on Wednesday as sunny skies, warm temperatures and dry conditions persist. PRECAUTIONARY/PREPAREDNESS ACTIONS... Sensitive groups, such as people with lung disease (including asthma), heart disease, children and older adults, and people who are active outdoors, should limit prolonged or heavy outdoor exertion. Reduce or eliminate activities that contribute to air pollution, such as outdoor burning, and use of residential wood burning devices. Reduce vehicle trips and vehicle idling as much as possible. && For information on current air quality conditions in your area and to; sign up for daily air quality forecasts and alert notifications by; email, text message, phone, or the EPA AirNow mobile app, visit; https://www.pca.state.mn.us/air-water-land-climate/current-air-; quality-conditions.
