However, the local fire danger remains high.“We’re holding our own here, but this wind is a big concern,” Chute said Monday morning. “We’ve been able to catch the fires we’ve had but that could change with these winds.”Fires have also erupted in the Spokane region, forcing evacuations and scorching several homes.
