Experimental Smoke Transport Forecast

Experimental HRRR Smoke Transport

Here is an experimental forecast model's output of smoke transport from the 416 Wildfire north of Durango. Areas of smoke and haze are expected today in portions of southwest Colorado. Winds are still on track to shift to the southwest late this morning/early this afternoon which will shift the projected smoke transport. Please take the necessary precautions if you are sensitive to smoke by minimizing outdoor activity.

 

Again, please note this product is experimental.
