After a brief respite from the haze, Portland is back to having an "unhealthy" Air Quality Index as of 6 p.m. Tuesday.

The AQI was ranked above 100 in Portland, which means the air could be unhealthy for everyone, especially those with lung or breathing problems.

Don't expect the haze and smoke to go anywhere Wednesday - there will be spotty hazy skies for much of the Valley.
