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.
All model forecasts are updated hourly and are forecasts for the next 18 hours, except for the "Extended" which is updated every 6 hours, and that forecast goes out 48 hours in time.
