Valdosta faces similar challenges, where emissions combine with regional geography to slow natural airflow. While seasonal pollen can influence air quality, PM2.5 remains the primary concern.

In Oregon, an extended Air Stagnation Advisory remains in effect across central regions and the Willamette Valley. Light winds and high pressure are trapping smoke from residential wood burning, vehicle exhaust, and other emissions. The Oregon Department of Environmental Quality has issued an Air Quality Advisory through early Friday morning.

Additional Weather Hazards

The National Weather Service has also issued freezing fog advisories in several Oregon counties, including areas around Eugene, Corvallis, Albany, and Springfield. Visibility may drop to a quarter mile, and rime ice could create slick road conditions during morning commutes.

Similar stagnant air conditions are affecting large portions of central, eastern, and northern Oregon, as well as parts of southeast Washington. Cities under alert include Bend, Medford, Grants Pass, Klamath Falls, The Dalles, and Yakima.

Safety Guidance

Officials strongly advise:

• Staying indoors when possible
• Avoiding strenuous outdoor activity
• Reducing wood burning and residential heating emissions
• Monitoring local air quality forecasts
• Using caution on roads during foggy and icy conditions

People with respiratory conditions, older adults, and young children are especially urged to take precautions.
