Stagnant air expected through Monday, NWS says

Stagnant air — a soup of haze, smoke and fog — is settling in for the weekend and beyond as a strong inversion traps pollutants in the air, with the potential to cause breathing issues for those already suffering with respiratory problems, the National Weather Service says. 

While not expected to return to conditions experienced earlier in September caused by wildfire smoke, the effects will likely linger through Monday, October 5.

It’s bad enough that the NWS in Portland issued what’s called a “Air Stagnation Advisory” on Thursday afternoon for locales in the region under 2,000 feet of elevation, which is scheduled to end 6 p.m. on Monday.
