Sunny skies, warm temperatures, and low humidity will create an environment favorable for two types of pollutants (Volatile Organic Compounds and Nitrogen Oxides) to react in the air to produce ground-level ozone. Ground-level ozone is expected to be in the Orange (Unhealthy for Sensitive Groups) AQI category across the alert area. Ozone will be highest during the afternoon and early evening hours when sunshine is most abundant, and temperatures are highest. Ozone concentrations will be lowest in the early morning hours. 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.
