DES MOINES, Iowa—The Iowa Department of Natural Resources has issued an Air Quality Alert for the state:

...The Iowa DNR has issued an Air Quality Alert for fine
particulate pollution, which is in effect for all of Iowa Through
Noon Monday...

Smoke from wildfires in Alberta and British Columbia continues to
sit across Iowa. Air quality is expected to improve statewide by
Monday morning, with smoke clearing from north to south starting
Sunday evening through Monday morning.

The DNR recommends that people reduce long or intense activities,
and take more breaks during outdoor activities until air quality
conditions improve. The recommendation is especially pertinent to
individuals with heart or lung disease, older adults, children and
teenagers, and outdoor workers. People in these categories should
consider rescheduling or moving outdoor activities indoors.
