The Oregon Department of Environmental Quality is issuing an air stagnation advisory for Klamath and Lake Counties through the morning of Thursday, January 3, 2019.

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.
