Highlights

Very dangerous avalanche conditions exist. A multi-day storm bringing heavy snowfall and strong wind is overloading a weak snowpack. Widespread avalanching will occur. Some will be large enough to snap trees or destroy a wood-frame house. Stay off of and out from below steep slopes—slopes steeper than about 30 degrees. Avalanches may be triggered remotely—from gentler terrain above, below, and to the sides of steep slopes. Avalanches may impact roadways, trails, and structures in the valley bottom.

This backcountry Avalanche Warning does not apply to the HWY 21 avalanche program.

A full Avalanche Forecast will be published tomorrow morning by 7:30AM.
