The following is information on the Cedar Fire for the morning of Sunday, August 21.
Officials say that the fire moved slowly south overnight, towards Black Mountain and Highway 155.
Crews said their priority today was keeping the fire from jumping Highway 155; it's currently on the north side and "backing" down the mountain towards Highway 155.
Wildfires tend to move more quickly uphill, but the south flank of the fire is currently moving downhill, giving crews time to prepare. They were observed today removing dry vegetation and fuel from around Highway 155, saying they'll use the road as a natural containment line if needed.
As of Sunday morning, the fire has burned 17,986 acres and is 5% contained. No structures have been damaged to this point.
Fire crews are also having to deal with an additional danger: weakened trees. Drought and other factors have contributed to a high tree mortality rate in the area, resulting in weaker roots and the potential for falling trees.
"That's the concern for our firefighters," said Nathan Judy of the U.S. Forest Service. "Making sure they're safe when they're out there, keeping their head on a swivel and watching every direction.
