Air Quality Alert issued June 7 at 5:38PM CDT by NWS Twin Cities/Chanhassen MN

* WHAT…The Minnesota Pollution Control Agency has issued an Air
Quality Alert for fine particles pollution. The Air Quality
Index (AQI) is expected to reach the Orange or Unhealthy for
Sensitive Groups category.

* WHERE…All of Minnesota.

* WHEN…From 11 PM CDT Friday evening to 11 PM CDT Sunday
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 Canadian wildfire smoke will
follow a cold front into and across Minnesota from west to east
from late Saturday night into Sunday morning and afternoon, and
then clear out from west to east across the state from Sunday
afternoon through Sunday evening. Some areas may only see a few
hours of alert-level smoke concentrations due to the relatively
fast movement of the north-south band of smoke. The air quality
alert may need to be extended into Monday if an additional batch
of heavy smoke materializes from Manitoba and Saskatchewan
wildfires and then is transported into and across Minnesota from
north to south, but confidence for this outcome is currently
low to medium.
