AVALANCHE PROBLEM TOOLBOX <here>
SNOWPACK DISCUSSION: Snowmachine triggered avalanches will be in the afternoon when the day time temperatures have reached above 32 degrees F. Numerous point release wet avalanches and wet slab avalanches have been triggered by sledders on south facing slopes. Although they are slow moving, these wet avalanches will easily entrain you into the snow.There is still a potential weak layer lurking on the north facing slopes at high elevations. If you will be climbing into the north facing slopes of mountains like Courage, No Name Glacier, College Glacier, or the Gakona Glacier you could trigger a persistent slab avalanche. Although likelihood is low, the consequences are high.
Recent Avalanche ActivityNumerous wet slab Avalanches were snowmachine triggered Thursday afternoon in areas like Gun Creek and on the big south facing mountain to the west of camp.
Recent WeatherRecent daytime temperatures have reached into the upper 30's. Night time temperatures are forecasted to drop into the high teens. Friday morning will bring sunny skies with a chance of snow in the afternoon. Daytime temperatures reaching close to 40 degrees F.
