South winds gusting as high as 40 to 45 mph will develop quickly by mid to late morning. Wind speeds will ease across east-central South Dakota by mid afternoon, while the stronger gusts linger in southwest Minnesota through sunset. These strong winds, combined with near-record warmth and humidity levels as low as 25 to 35 percent, will produce elevated fire weather concerns today. Grassland fire danger will reach the High category, with locally higher fire danger in cured croplands and grasses. Avoid outdoor burning and use extra caution with equipment in dry crops, as rapid fire spread is possible. In addition to the elevated fire danger, winds gusting over 40 mph may produce areas of blowing dust, locally reducing visibility and air quality.

WHAT: The Minnesota Pollution Control Agency has issued an Air Quality Alert for course particles pollution. The Air Quality Index (AQI) is expected to reach the Orange or Unhealthy for Sensitive Groups category.
-
WHERE: West central and southwest Minnesota.
-
WHEN: From 7 AM CDT to 7 PM CDT Saturday.
-
IMPACTS: Sensitive groups, such as people with lung disease (including asthma), heart disease, and children and older adults, may experience health effects.

Decreasing winds will lessen the potential for impacts through the evening.

Sensitive groups, such as people with lung disease (including asthma), heart disease, and children and older adults, should limit prolonged or heavy exertion. 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.
