Summary: Animated forecast of near-surface smoke concentrations in the Pacific Northwest for August 11-15, 2026, showing hourly air quality predictions over Oregon, Washington, and Idaho.
This video presents an animated forecast from the RRFS model for near-surface smoke concentrations (µg/m³) across the Pacific Northwest, specifically covering Oregon, Washington, and Idaho, from August 11, 2026, 07:00 PM MDT to August 15, 2026, 05:00 AM MDT. The animation steps through hourly predictions, illustrating the movement and intensity of smoke plumes. Initially, significant smoke is observed in central Oregon, western Washington, and central Idaho. Over the forecast period, smoke patterns shift, with some areas experiencing a reduction in high concentrations, while others maintain moderate to high levels. The forecast provides a visual representation of evolving air quality due to smoke.
