...AIR QUALITY ADVISORY REMAINS IN EFFECT UNTIL NOON PDT FRIDAY...
The Southwest Clean Air Agency and the Oregon Department of
Environmental Quality continues an Air Quality Advisory until noon
Friday.
Smoke and haze remains in the region and will cause air quality to
reach unhealthy levels at times through Friday morning. Conditions
have slightly improved today and will continue to improve through
Friday. However, hazy skies will remain over the region.
Wildfires burning across parts of Washington and Oregon have been
creating abundant smoke. Low level smoke that drifted into western
Oregon along the Columbia River earlier this week has thinned with
conditions slowly improving. Higher level smoke from the wildfires in
southern Oregon remain over the area.
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.
