Additional Details: Very heavy smoke is expected across the Arrowhead today, as large wildfires continue to spread. Hot temperatures, when combined with the air pollution, will exacerbate health impacts. A frontal boundary will then spread heavy smoke further south this evening into Wednesday morning, as it moves across northern and central Minnesota. The onset of smoke will be rapid. This boundary eventually passes through the Twin Cities and into southeastern Minnesota on Wednesday or Wednesday evening, bringing heavy smoke even further south. Additional rounds of heavy smoke are possible from Thursday through Friday morning across the alert area.

Sensitive groups, such as people with lung disease (including asthma), heart disease, and children and older adults, should remain indoors and keep activity levels low. The general public should avoid all physical activities outdoors. 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.
