An air quality advisory for much of Oregon and southwest Washington that was initially expected to last only through Tuesday night, has now been extended for at least a week.
Smoky conditions and lack of air movement spurred the advisory which was first announced November 4th. Now officials with several regional agencies - including the Oregon Department of Environmental Quality (DEQ), Southwest Clean Air Agency, and Lane Regional Air Protection Agency (LRAPA) say it’ll last through at least Tuesday, November 12th.
Susan Mills of the DEQ says there’s a lack of wind and rain in many parts of the region, causing stagnation.
“Wood smoke and other pollutants such as vehicle emissions will stay close to the ground, and make it more unhealthy for sensitive groups.”
That includes pregnant women, children, seniors, and people with respiratory or cardiovascular issues. Residents are advised to limit burning, and use High-Efficiency Particulate Air (HEPA) filters in heating and ventilation systems.
Geography can also be a factor. Residents in deep valleys and basins are more apt to experience stagant air mass than those in wider areas, including the coast.
