A large portion of South Dakota is already bracing for some oppressive heat this weekend with elevated humidity levels driving the heat index well into the triple-digits across the Mount Rushmore State.

But blazing hot temps aren't the only thing we'll be dealing with.

Late Friday (August 18), the South Dakota Department of Agriculture and Natural Resources issued an air quality alert for areas across South Dakota where smoke from wildfires is forecasted to settle this weekend.

The smoke may cause low visibility and increased fine particulate matter pollution. The South Dakota Department of Health advises that these levels may be a concern to public health.

The alert will stay in effect through Sunday (August 20) or until conditions improve.

Officials are advising anyone in these areas to avoid excessive physical exertion and minimize outdoor activities. Senior citizens, young children, and individuals with respiratory problems are the most susceptible to the smoke.
