TWISP — The Gilbert Fire, burning about 21 miles west of Twisp, has grown to about 7,000 acres.

Level 2 evacuation notices (be set to leave) have been issued for residents above the road closure at the intersection of Buttermilk Road and Twisp River Road. The fire is expected to continue to move to the east, which could put residents in the upper Twisp River area on Level 3 (leave now) evacuation notices, according to the press release issued Saturday morning from the Okanogan-Wenatchee National Forest.

The fire’s growth has been mostly to the southeast into Williams Creek.

About 110 personnel are working the fire as of Saturday morning. Fire crews are gearing up to protect structures in the Twisp River drainage. A Type 1 Incident Management team has arrived and command of the fire will be transferred Sunday morning.

The lightning-sparked fire was reported July 28.
