Avalanche Warning

The next round of snow develops late Saturday night into Sunday morning around the mountains. The snow may fall heavy at times around the Cascade crest, near Stevens Pass, in the morning. Elsewhere initially snow levels over northern Washington and the ID Panhandle will start off near 2000 feet with slushy accumulations of less than 1" expected in the valleys. As snow levels rapidly rise Sunday afternoon into Sunday night, all the mountain passes will change over to rain.

The Idaho Panhandle Avalanche Center has issued a Backcountry Avalanche Warning for the Selkirk, West and East Cabinet and Bitterroot Mountains and Silver Valley above 4000 feet through 6 AM Sunday. The Northwest Avalanche Center in Seattle has issued an Avalanche Warning for the west slopes of the Washington Cascades through 6:30 PM Sunday. Travel in avalanche terrain is not recommended during this period. The combination of heavy snowfall and strong winds has formed dangerous slabs of snow two to three feet thick that are overloading weaker snow layers directly below the new snow. It will be very likely for backcountry travelers to trigger large to very large avalanches in the new snow and natural avalanches are likely.
