In Carbon County, Wyo., firefighters are evaluating areas north of the fire where they may have to defend buildings should the fire make a push in that direction.
Fire managers say storm cells moving in from the south mark the first time in over a week the weather forecast calls for conditions that may reduce fire activity.
"We've got a road here called the six-hundred road that has somewhere between a dozen and twenty structures, and it is right in the heart of the fire," Davis says.
Crews are fanning out from the fire's edge into Wyoming in search of areas where firefighters could directly engage the flames with a high probability of success.
Firefighters, now numbering 514 in total, will not directly engage the fire in the Mount Zirkel Wilderness area, opting instead to patrol and assist Forest Service staff in keeping recreationists apprised of the area closure.
