SPANISH FORK — Crews continue to increase containment on the joint fires blazing in Utah County.
The Pole Creek Fire is burning 102,104 acres and was 68 percent contained Friday. The adjacent Bald Mountain Fire is burning 18,608 acres and was 76 percent contained, according to a daily update from fire managers.
About 1,100 firefighters continue to work on the fires. Earlier this week, nearly 1,600 firefighters were on scene.
Crews Friday were mopping up and patrolling areas of the Pole Creek Fire. They were also working to prevent fire growth to the west into Salem, Payson and infrastructure on North Nebo Mountain.
Crews were also mopping up areas affected by the Bald Mountain Fire.
The estimated containment date for both fires is Oct. 10, fire managers said.
As two different storm systems could move into Utah next week, Utah County officials Friday evening expressed concern about potential mudslides and debris flows.
"Utah County Emergency Management officials want residents who live near the areas impacted by these fires to be aware of the risks and have as much time as possible to prepare for approaching storms," according to a news release from the county.
"We cannot predict with certainty what areas would be impacted in an emergency, but we want everyone to be prepared to respond should the need arise."
Information about how to prepare for potential emergencies can be found on Be Ready Utah, the state's emergency preparedness website.
