Forest fires in the West Mountain Complex continued to grow amid hot, dry and windy conditions.Fire conditions across the region have been so hectic that fire managers have had to report approximate numbers for containment on the Boulder and Lava Fires to the southwest of Cascade.“I’ve worked here since 1995, and I have never seen such a complex fire situation as we’ve had these last two months,” said Brant Peterson, the Forest Supervisor on the Boise National Forest at a meeting at the Cascade Fire Station on Tuesday evening.Evacuation orders along West Mountain were expanded Monday and Tuesday, and officials warned that they could change rapidly.To sign up for Valley County’s emergency evacuation alert system CodeRed, visit www.co.valley.id.us/CompleteEmergencyNotificationandAlerting.Cascade and the surrounding area has been broken down into zones, with evacuation orders issued for specific areas.To view a map of specific zones, visit www.co.valley.id.us/departments/EmergencyManagement and select “Valley County Hazards and Risk Map.”On Sunday, conditions aligned to create “extreme fire behavior,” with the Lava Fire growing from about 2,500 acres to almost 47,000 acres, joining with the western perimeter of the Boulder Fire and progressing north along West Mountain.The fire grew yet again on Monday, reaching about 69,000 acres and about 70,000 acres as of Tuesday evening and a combined 78,000 with the Boulder Fire footprint included.It had burned within a quarter mile of homes along West Mountain Road in some areas.“The homes that are in front of these fires are our number one priority,” said Kevin Wright, an administrator with the Boise National Forest.As the fire expanded, firefighters continued work to prevent the blaze from destroying homes along West Mountain Road.Controlled burns were done Tuesday to slow the fire’s progression into Willow Creek and elsewhere along the hillside.Crews also continued to construct fireline with bulldozers and prepare structures in the West Mountain area by removing brush and establishing hose and sprinkler lines.As of Tuesday, approximate numbers were listed for the Boulder Fire as 24% contained at about 8,800 acres.The cost of the Boulder Fire was about $33.9 million as of Tuesday, with about $2.5 million spend on the Lava Fire so far.
