Wildfire Smoke Impacts U.S. Air Quality

Wildfire smoke from numerous fires in Oregon, Washington, and British Columbia is spreading over a vast stretch of approximately 2,500 miles. This smoke is moving across the Plains, Midwest, and into the East, creating visible effects and affecting air quality.

Starting July 27, 2026, and continuing onwards, the smoke will result in hazy skies in the eastern part of the United States. It is expected to diminish the air quality in the Northwest and sections of the Plains significantly. This will lead to potential health concerns, especially for individuals with respiratory issues.

Authorities have advised people in the affected areas to stay indoors when possible and limit strenuous outdoor activities. The situation highlights the broad impact of wildfires on both the environment and public health.
