...AIR QUALITY ADVISORY IN EFFECT THROUGH FRIDAY MORNING...
The Southwest Clean Air Agency and the Oregon Department of
Environmental Quality have issued an Air Quality Advisory, which
remains in effect until noon Friday.
Smoke will remain in the region, and will cause air quality to reach
unhealthy levels at times through Friday morning. Conditions will
gradually improve later today, with more improvement Thursday and
Thursday night. However, hazy skies will remain.
Wildfires burning across parts of Washington have been creating
abundant smoke. Low level smoke that drifted into western
Oregon along the Columbia River earlier this week still remains over
the region. But, this smoke is gradually thinning today through
Thursday, with conditions slowly improving. In addition, smoke
continues to filter into the region from the north, affecting areas
along the Cowlitz River Valley.
Pollutants in smoke may cause burning eyes, runny nose, and can
aggravate other serious health problems. Limit outdoor activities and
keep children indoors if it is smoky.
