The Air Quality Index (AQI) is expected to reach the Orange or Unhealthy for Sensitive Groups category. * WHERE...Northeast Minnesota. * WHEN...Until 7 PM CDT this evening. * IMPACTS...Sensitive groups, such as people with lung disease (including asthma), heart disease, and children and older adults, may experience health effects. * ADDITIONAL DETAILS...Heavy surface smoke continues to rotate northwestward around an area of high pressure and into northeastern Minnesota, and is therefore expected to persist through the afternoon. Southerly winds will result in increasingly cleaner air with time, and fine particle pollution concentratinos should drop below the alert threshold by this early evening. PRECAUTIONARY/PREPAREDNESS ACTIONS... Sensitive groups, such as people with lung disease (including asthma), heart disease, and children and older adults, should limit 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.
