An infrared flight last evening showed that the #mullenfire_wy has grown to 151,700. Containment is 14% and there are 1,104 firefighters working on the fire.Yesterday, firefighters conducted successful firing operations in several locations around the perimeter of the fire to widen existing firelines. Structure protection remains in place throughout the fire area. Today is going to be a Red Flag day with low humidity levels and strong west winds, which will switch to the northwest. Expect wind gusts to 35 mph throughout the day with active burning as fire consumes dead and down fuels. Smoke production will be high again today and will spread to the east as fuel within the fire perimeter is consumed.
