    Rain at lower elevations will keep the surface snow moist or wet and promote sluffing in steep terrain.

Avalanche Summary

No new avalanches have been reported in the region. Please submit your observations to the Mountain Information Network.

Snowpack Summary

In most places a combination of rain and warm temperatures has likely made the surface snow moist or wet. High elevation alpine and especially north aspects may still hold dry snow. If there has been a good overnight freeze, you may find a supportive crust on the surface. The mid and lower snowpack pack are likely a mixture of moist snow and crusts. Below treeline the snowpack has melted or is isothermal.
