Fire activity on the Chilliwack Complex fires has significantly decreased in the past several days with changing weather conditions and increased moisture across the area. Minimal fire behavior has been observed. However, these lightning-caused fires in the back country will continue to burn until the fire area receives significant moisture or snow. The Chilliwack Complex InciWeb will no longer be updated with current fire information unless there is significant new activity to report. To check on the status of trail and area closures, please call the Chilliwack Complex Fire Information # at (360) 391-7269 or visit the North Cascades National Park Complex website at:  North Cascades National Park (U.S. National Park Service) (nps.gov).

There are a number of lightning-caused fires burning in remote, steep and inaccessible terrain in the Stephen Mather Wilderness in the northwest corner of the North Cascades National Park Complex in Washington State. The Chilliwack Complex is made up of several active fires (Little Chill, Copper Lake, Brush Creek 2, Silesia, and Little Beaver Creek).

Trail and camp closures remain in effect due to fire activity. Closure information can be found at: https://www.nps.gov/noca/planyourvisit/trail-conditions.htm

A haze over the general area is to be expected with active fires across the region. The Washington Department of Ecology has announced Air Quality Alerts in multiple locations due to current wildfire smoke from fires in the North Cascades. Visit https://wasmoke.blogspot.com/ for details.

Take precautions when recreating outdoors when heavy smoke is present. Current Smoke Outlook for North Cascades (wildlandfiresmoke.net) Learn more at Real-Time Air Quality Map | PurpleAirairnow.gov or visit https://wasmoke.blogspot.com/.

Current Weather

Weather Concerns

Morning fog was followed by afternoon sunshine which filtered through high clouds over the complex today. Light winds were observed with relative humidity dropped into the 40-50 percent range. Skies will clear overnight as north winds funnel across the region. Gusty winds are possible especially on the ridges. Sunday will feature the first of several days through next week with mainly sunny skies, breezy afternoon winds, along with as low warming and drying trend under west to north winds. Winds and humidity may bring elevated fire weather concerns towards mid-week, but no rain or critical fire weather is expected at this time. A strong low-pressure system moving into California is expected too mainly impact areas south of Washington State with heavy rainfall this weekend into next week.
