Updated 9:50 a.m., Friday, Sept. 18

Air quality is quickly improving in much of the state and across the Portland metro region, but we are not breathing healthy air yet. Particulate matter concentrations from wildfire smoke have plummeted. We are currently seeing the lowest hourly readings since the morning of September 10th. 

Yesterday’s 24-hour particulate matter average was 175 micrograms per cubic meter (ug/m3), decreasing to the lowest concentrations since Sept. 11.

Expect unhealthy air to remain across much of the county today. Wait to open windows and doors until air monitors show yellow “Moderate” air quality in your area. Check conditions on Oregon Smoke Blog and download the OregonAir phone app.
