ORIGINAL
KLAMATH FALLS, Ore. - The National Weather Service in Medford issued an air stagnation advisory, which is in effect from 4 a.m. Friday, January 25, to noon Monday, January 28.
Poor mixing heights and light winds will keep stagnant conditions in place through at least Monday morning. Pollutants may be trapped near the ground level and this may result in reduced air quality at times.
Diminished air quality can create respiratory problems, especially for sensitive groups, such as those with asthma or other lung diseases.
The air stagnation advisory predicts there will be little or no wind in the Klamath Basin. Smoke and other airborne pollution will increase in concentration, causing a build-up that will not be carried out of the basin. The increase in airborne pollution can be unhealthy for outdoor physical activity and may contribute to health problems including coughing or aggravated asthma.

To reduce pollution buildup, the Klamath County air quality and burning advisory is red, starting at 8 a.m. today, January 24. It will remain in effect until noon on Monday, January 28. Check the advisory each day for possible updates at https://www.klamathcounty.org/383/Air-Quality
