KLICKITAT COUNTY, Wash. -- The Dry Creek fire, burning in Klickitat County, about 7 miles north of Husum, Washington, since Friday, grew to 400 acres Sunday night.

People are being asked to avoid the area if possible.

Chuck Turley, the public information officer for the fire operation, said two homes were under a Level 2 evacuation. On Sunday night, the Klickitat County Sheriffis Office went door to door advising people about possible evacuations.

A Level 1 evacuation notice has been issued for people living north of Meyers Road and south of Pine Flat Road on both sides of Highway 141. Level 1 means be on alert, Level 2 means be ready to leave just in case and Level 3 means people must leave immediately.

A Red Flag wind warning was issued Sunday, to alert agencies that conditions are ideal for combustion and rapid spread of a wildland fire.

The fire was first reported at about 10:30 p.m. Friday. Crews began fighting the fire on Saturday and were able to keep it to about 25 acres until hot winds in the afternoon caused the fire to spread.

Crews continued battling the fire overnight Sunday and into Monday morning.

The fire has shut down parts of State Route 141, including a full closure in both directions from BZ Corner to Sunnyside Road, according to the Washington State Department of Transportation. A roughly 20-mile detour is in place using BZ Glenwood Highway and Trout Lake Glenwood Highway.

Recreational access to portions of the White Salmon River from BZ Corner Boat Launch north to Warner Road have been closed.

Fire investigators are looking into the cause of the fire. Officials said in about 80 percent of cases, fires are caused by humans.
