Smoke Outlook for 9/16 - 9/17 _ NW Oregon Willamette Valley
Oregon Department of Environmental Quality has extended the AIR QUALITY ADVISORY for the entire State of Oregon due to hazardous smoke conditions.
Fire activity on the Riverside and Beachie Creek fires has slowed significantly, showing small pockets of heat along the fireline where crews are working to get access. Today's cooler temperatures and incoming low pressure will help firefighter efforts. Internal pockets and dense understory will continue to smolder and clean up through the week.
Today, expect to see air quality improve as this low-pressure meanders inland. The stalled low-pressure system has scoured out the lingering smoke in Tillamook, Florence, and Coos Bay. The Willamette Valley is starting to see some relief, but fires in California continue to send smoke into Oregon up the I-5
corridor. Levels of particulate matter will drop below 200 for the first time in a week. Most of Portland will feel improvement as levels bounce between USG and Very Unhealthy today. Salem and Albany will stay in the Very Unhealthy range into the evening. Eugene won't see as much relief, with levels
above 200 (hazardous) for most of the day. Corvallis, Albany, Sweet Home, and Oakridge will continue to see improvement towards unhealthy levels throughout the day.
