Smoke from wildfires across the state is pushing air quality into dangerous levels in parts of Central and Southern Oregon.

The Oregon Department of Environmental Quality issued an air quality advisory as air quality index readings topped 150 Wednesday morning near Bend and La Pine, made worse by smoke from the Cram Fire near Madras.

Further south in Klamath and Jefferson counties, the AQI climbed over 170, affected by smoke from fires burning across Southern Oregon.

The Klamath County Public Health Department issued a health alert Wednesday for county residents. That DEQ advisory is in effect until at least 10 a.m. Thursday, while conditions are expected to slightly improve before then in Deschutes and Crook counties with intermediate smoke remaining.

AQI levels range from 0-50 for “good” air quality to 300-500 for “hazardous” conditions.

Public health officials are encouraging people affected by poor air quality to stay safe by:

  • Avoiding strenuous outdoor activity
  • Using air purifiers
  • Running air conditioning on recirculate mode
  • Keeping windows and doors closed
  • Using N95 masks, particularly for vulnerable groups such as children and the elderly
  • Keeping pets indoors — as much as possible

“Wildfire smoke contains fine particles that can be harmful to your health. People at the highest risk are those with health conditions, older adults, children and infants,” Deschutes County Public Health Director Heather Kaisner said in a press release. “People who have asthma or other lung conditions should keep medications available and contact their healthcare provider if necessary.”

Multiple counties are also providing the public with cleaner air-conditioned locations to visit, such as local libraries to avoid the smoke and heat.
