Park closures remain in effect as crews monitor backcountry fire activity

The Luna Fire continues burning in remote, steep timber southwest of Luna Camp and north of Newhalem within North Cascades National Park. Fire activity over recent days has remained moderate with backing and flanking, while crews make steady progress securing lines west of Ross Lake. No communities are currently threatened, though the fire remains a concern for backcountry structures and regional energy infrastructure.

Evacuations and Closures

• No evacuation watches, warnings, or advisories are in effect for Whatcom County communities as of September 10.
• Backcountry area, trail, and camp closures remain in place within North Cascades National Park, including the Big Beaver Trail area, as of September 10.
• A countywide Stage 2 burn ban prohibiting all open burning remains active across Whatcom County as of September 10.

Impact

Smoke from the Luna Fire and regional wildfire activity has produced moderate air quality across Whatcom County. Point protection and risk assessments have been established around Diablo and Ross Lake Resort, with no structural damage reported.

Conditions and Outlook

Winds will shift from southwest to southeast over the coming days before cooler, damp conditions bring humidity recovery and a chance of precipitation late in the weekend. Firefighters plan to continue perimeter monitoring and line improvement while the fire exhibits creeping and backing behavior in heavy forest litter.

Cause and Context

The fire was ignited by lightning in steep, rocky terrain and is managed by the North Cascades National Park Service Complex.
