A fire in southwestern Cassia County has burned more than 5,500 acres.
The Sawtooh National Forest said the Badger Fire is near Badger Gulch, south of Bostetter Guard Station near Forrest Service roads 533 and 536.
A type 3 interagency management team is expected to arrive Monday afternoon to lead firefighting efforts.
An air quality caution was issued for the eight south-central Idaho counties Monday when the air was unhealthy for sensitive groups due to wildfire smoke, mostly from other states. All outdoor open burning is prohibited by the Idaho Department of Environmental Quality.
The air quality for the rest of the week is expected to stay moderate or unhealthy for sensitive groups.
