Washington Evacuation Update: Little Giant Fire Orders, Okanogan Closures, and What Residents Need to Know

Multiple active evacuation orders and warnings remain in effect across north-central Washington as the Little Giant and surrounding fires continue to threaten communities in the Cascades and the Okanogan Highlands. Here is what affected residents need to know this weekend.

Little Giant Fire: Active Evacuations Near Leavenworth Corridor

The Little Giant Fire — burning approximately 30 miles northwest of Leavenworth in the Okanogan-Wenatchee National Forest — is the most actively evacuated fire area in Washington as of September 5. Evacuations, area closures, and road and trail closures are in effect in the fire's vicinity.

The incident is exhibiting moderate fire behavior with backing and flanking activity. Numerous structures and critical infrastructure remain threatened. Residents and property owners in the affected drainages should not re-enter evacuation zones until official clearance is given by local emergency management — even when visible smoke activity appears reduced, fire can remain active and dangerous within the perimeter.

The California Incident Management Team (CA Team 5) is currently managing the incident, with NW Team 12 mobilizing to assist and also managing the adjacent Sisi Fire incident.

Okanogan County: Sinlahekin and Ptarmigan Fires

Okanogan County — a perennial focus of Washington's fire season — is dealing with at least two significant active fires. The Sinlahekin Fire was 38% contained as of September 3 and has affected the Sinlahekin Wildlife Area and surrounding ranch and forest lands. The Ptarmigan Fire prompted evacuation orders in early September as it moved through dry fuels in the county.

Okanogan County has maintained an active emergency operations structure throughout the summer, coordinating with the Washington State Patrol, DNR, and the U.S. Forest Service on evacuation enforcement and public information.

North Cascades: Thunder Creek Fire (NPS)

The Thunder Creek Fire in North Cascades National Park — approximately 13 miles southeast of Newhalem — has triggered closures of backcountry areas in the park. The NPS has closed affected trail corridors and wilderness zones. Hikers and backpackers planning trips into the park's Thunder Creek drainage should check current closure status with the North Cascades National Park visitor center or at recreation.gov before traveling.

Washington Evacuation Level System

Washington State uses a three-level evacuation notification system:

Level 1 — Be Ready: Be aware that a situation exists in your area. Be ready to evacuate if the situation worsens. Gather emergency supplies and be prepared to leave on short notice.
Level 2 — Be Set: Evacuate if you have special needs, have livestock, or feel threatened. Those who do not evacuate must be prepared to leave at a moment's notice.
Level 3 — Go Now: Leave immediately. The area is immediately threatened or affected by the hazard. Do not delay departure to gather belongings.

Always follow Level 3 orders immediately. Residents who remain in Level 3 evacuation areas do so at extreme personal risk and may delay emergency response operations.
