ST. PAUL, Minn. — Multiple waves of Canadian wildfire smoke will drift across Minnesota through Saturday. A health alert from the state Pollution Control Agency predicted unhealthy conditions for vulnerable people across 20 southern Minnesota counties. The advice: Stay indoors. It’ll be worse farther north all the way to Canada. Winds are transporting waves of heavy surface smoke from wildfires across Manitoba and Saskatchewan.
