Kernpunkte

Another warm and soggy day will keep the snowpack from freezing and gaining strength. Wet avalanches remain a concern, particularly in areas above 6000ft near the Cascade Crest. Steer away from cornices and large consequential slopes during the ongoing thaw.

    Wet loose activity may continue, with the most reactive conditions expected for the first half of the day Wednesday before winds increase in the afternoon. Anywhere from 4-12in of wet snow sits on a crust, and could slide easily with a human trigger in steep, unsupported terrain. Wet loose avalanches could gouge into the snowpack, build significant mass, and run far downslope. When you find wet sticky snow or see new avalanches, dial it back and stay off of and out from under steep slopes. We expect most of the natural avalanche activity to stay small, but you could see a larger avalanche in big complex terrain at upper elevations where more snow accumulated over the past few days.

Avalanche Discussion

Skies cleared Tuesday afternoon as the strong March sun beat down on a soggy snowpack with mountain temperatures reaching over 50F. Widespread wet loose avalanche activity was reported in adjacent zones and similar conditions are suspected in the East South. Storms since Friday brought up to 1ft of cold dry snow with precipitation favoring areas above 6000ft near the Cascade Crest. The deeper the recent snow, the more there will be to entrain as wet avalanches run in the coming days. Wet avalanche activity may have already peaked, but will likely be ongoing with additional rain, warming, and sunshine through the end of the week.

The East South zone is certainly not breaking any records for snowpack depths this winter. The warm temperatures associated with recent storms kept snow accumulations minimal at elevations below 6000ft. Below treeline areas have very little or no snowpack and many southerly aspects are melted out to ridgetops. Utilizing roads and summer trails to access higher elevations with a more robust snowpack is the best option. Travel cautiously, especially at lower elevations, to avoid impacts with rocks or stumps, and beware of open creeks.
