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

WHERE: East central and central Minnesota.

WHEN: From noon CDT to 9 PM CDT Tuesday.

IMPACTS: Sensitive groups, such as people with lung disease
(including asthma), heart disease, children and older adults, and
people who are active outdoors, may experience health effects.

ADDITIONAL DETAILS: Ground-level ozone is expected to be high
on Tuesday afternoon in the Twin Cities metro area and central
Minnesota. Mostly sunny skies, warm temperatures, and low
humidity will provide a favorable environment for two types of
pollutants (volatile organic compounds and nitrogen oxides) to
react with sunlight in the air to produce ground-level ozone.
Ozone is expected to reach unhealthy levels during the afternoon
and will subside in the early evening.
