The National Weather Service Office in Portland has extended and expanded the Air Stagnation Advisory for the Portland Metro area and Willamette Valley through at least 6 PM Sunday.
An Air Stagnation Advisory is issued when very little wind movement settles into the area for extended periods of time. This means the air trapped here in the valley does not really move onward bringing in fresher air. As time goes on, pollution has the potential to increase as it stalls in the valley. People that are sensitive to air quality may experience difficulty breathing along with other health problems.
In efforts to help reduce this health risk, Clark County issued a Stage 1 Burn Ban on Monday January 14th. More information in regards to how that may effect you can be found in our Blog from Monday. For more information on Air Quality in your area please visit the Southwest Air Quality Index or State of Oregon DEQ Air Index.
