Air Quality Alert issued June 7 at 5:43PM CDT by NWS Duluth 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 this evening to 11 PM CDT Sunday.

* 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.
