The size of the Microwave Tower Fire west and south of Mosier is now at 591 acres.

Oregon Department of Forestry Public Information Officer Andy Dwyer said during the night firefighters were able to make good progress on the southern end of the fire, but the most challenging area is west of Mosier as the fire backs down toward Interstate 84 in difficult terrain and steep slopes.

Dwyer adds air resources have played a critical role in helping slow the fire’s spread.

The Type 1 Great Basin National Team currently managing the Whiskey Creek Fire southeast of Cascade Locks will assume command of this fire from the Oregon Department of Forestry’s Central Oregon District on Wednesday morning.

An incident command post will be setup at Hood River Valley High School.

The Oregon State Fire Marshal’s Office has sent two strike teams and three task forces to provide structural protection.

The Wasco County Sheriff’s Office says evacuation orders will remain in place into Wednesday morning.  Level 3 “Go Now” is in effect from Hwy 30 south to Proctor Rd., east to Huskey Rd and the border of the City of Mosier and west to the Hood River County line.    Level 2 “Get Set” to evacuate advisories have been issued for the city of Mosier and from Huskey Rd. east to Mosier Creek Rd., and south to Wilson Road.  A Level 1 “Be Ready” advisory is in place from Mosier Creek Rd., east to Dry Creek Rd., north to the City of Mosier border and south to Osborn Cutoff Rd.  The gymnasium at the Hood River Middle School is a designated Red Cross Shelter for those evacuating the fire in Mosier.
