The Sourdough Fire has seen a season slowing event over the last two weeks with cooler temperatures, higher humidities, and slight moisture across the area. Above normal temperatures and below normal precipitation is expected throughout the next week bringing warm and dry conditions; minimal to moderate fire behavior is expected. Smoke may be visible from State Route 20 from heavy, downed fuels smoldering in the interior of the fire perimeter.  The Sourdough Fire is at 6,280 acres and 25% containment.

Visitors should be aware of fire restrictions in all areas of the park complex. Campfires or the ignition of wood, briquettes, or any fuel in fire pits, fire pans, and barbeque grills, are banned in in all portions of North Cascades National Park Service Complex – North Cascades National Park, Ross Lake National Recreation Area, and Lake Chelan National Recreation Area. This includes all National Park Service lands and campgrounds along State Route 20 as well as Hozomeen and the entire Stehekin Valley. If you see smoke or flames dial 911 or report to a park visitor or information center.
