Whatcom County residents can once again breathe easier because air quality has improved after a weekend of hazy skies caused by wildfires, including one that has burned more than 4,300 acres in North Cascades National Park north of Marblemount.
Smoke from wildfires in eastern Washington and Idaho moved into western Washington, and then made its way north.
Over the weekend, air quality in Mount Vernon in Skagit County was unhealthy at points. In Bellingham and other parts of Whatcom County, it hovered between the moderate and unhealthy level for sensitive groups, meaning children and people with conditions such as asthma needed to limit time spent outdoors.
Shifting winds started to clear out the smoke in western Washington beginning Sunday afternoon, Aug. 23.
But the sky was expected to stay hazy in places because of residual smoke and humid air, according to the National Weather Service.
As of Monday afternoon, air quality was expected to continue to be good on Tuesday.
