The Southwest Clean Air Agency and the Oregon Department of
Environmental Quality continues an Air Quality Advisory due to
elevated levels of ozone pollution, or smog. The advisory covers
the Portland-Vancouver metro area to the Salem area. The advisory is
in effect until 6 AM Thursday.

Air quality agencies expect pollution to reach levels that could be
unhealthy for sensitive groups, including children, pregnant people,
older adults, and people with heart disease or respiratory
conditions. Health officials recommend that people limit outdoor
activity when pollution levels are high.
