In sintesi

Increasing winds and light snow could increase the avalanche hazard on Monday, particularly in the alpine.

Watch for changing conditions as the weather system moves through, and climbers should pay attention to what is going on in the terrain above them.

    Winds have picked up to moderate from the NW, and are forecasted to increase slightly more as they shift to westerlies on Monday and Tuesday. This along with some light snow flurries could develop wind slabs in leeward features.

Moderate

Avalanche Summary

No new avalanches have been observed or reported in the past few days.

Snowpack Summary

30-40 cm of soft snow overlying a supportive snowpack to ground. Wind affected surface snow can be found in the high alpine and some exposed tree line features.
Snow cover in the alpine varies greatly, with some areas blown free of snow, while other areas are filled in. A 2cm thick crust is present halfway down the snowpack but has only been observed at tree line elevations.
