Smoke will move south across all of Minnesota and linger through Saturday afternoon. The smoke will be reinforced by an area of high pressure that will create light winds and limit the dispersion of smoke. Heavier smoke is now expected to make it into southern Minnesota, therefore all of Minnesota will likely experience Red/Unhealthy AQI at times through Saturday afternoon when the air quality is forecasted to improve. Very dense smoke is located over Lake Superior, and the AQI forecast has been upgraded to Purple, which is very unhealthy air quality. 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.
