Puget Sound Clean Air Agency forecasters predict unhealthy smog levels for the Cascade foothills in King and Pierce counties Saturday and Sunday.
The forecast calls for hot and stagnant weather — conditions conducive to high ozone pollution levels. Exposure to ground-level ozone can trigger asthma attacks, make breathing difficult, weaken the immune system and exacerbate lung and heart problems.
The state Department of Health recommends for people sensitive to air pollution limit time spent outdoors. Air pollution can be especially harmful to children, people with heart and lung problems and adults older than 65.
The smog is most likely to impact Cascade foothills communities, including Issaquah. The suburban and rural areas accumulate pollution generated by traffic and other activities in Seattle, Everett and Tacoma.
In addition to smog, fine particle pollution levels might reach moderate levels in most areas throughout the Puget Sound region. The elevated pollution levels should last at least through Tuesday.
