Southern Oregon and Northern California Smoke Forecast from the HRRR model

10/01/2025 Videos are now locally generated at the office. The server is more reliable, although data could still drop from time to time.

These forecasts are directly from the model, not always accurate, and are best utilized as an indicator for trends vs. absolute air quality. Please ensure you check actual smoke conditions/air quality before making decisions about air quality.
