Some air quality advisories due to smog have been lifted on Thursday for the Portland-Vancouver metro area and Marion County.
The Southwest Clean Air Agency and Oregon Department of Environmental Quality say there are no longer elevated levels of ozone pollution or smog in the area.
Smoke from area wildfires is expected to impact portions of NW OR & SW WA the next few days. Here is a forecast of what the smoke in the atmosphere might look like. Some of this smoke might make it to the surface, causing the smell of smoke & poor air quality. #ORwx #WAwx pic.twitter.com/sxg7hHGZXt

But the air quality advisories due to wildfire smoke are still in effect through at least Friday along some parts of Central Oregon, along the Cascades in Southern Oregon and in the Harney Basin in Eastern Oregon.
Officials warn pollutants in wildfire smoke can cause burning eyes and a runny nose. They can also aggravate other serious health problems.
People in sensitive groups such as children, older adults, or people with heart or lung diseases are urged to limit outdoor activities.
The SWCAA urges people to help improve air quality by reducing pollution from cars, mowers, paint and aerosol sprays while alerts are in effect.
