High temperatures will be in the 90s across the alert area Tuesday, and the combination of wildfire smoke and extreme heat amplifies health risks. Heavy smoke may move further south into Minnesota Tuesday night into Wednesday morning, so the air quality alert may need to be expanded. Additional rounds of heavy smoke are possible across the region through at least Thursday morning. PRECAUTIONARY/PREPAREDNESS ACTIONS... Sensitive groups, such as people with lung disease (including asthma), heart disease, and children and older adults, should avoid all physical activities outdoors. The general public should avoid prolonged or heavy 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. Keep windows closed overnight to prevent smoke from getting indoors. && 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.
