    Winds are increasing out of the SW which will create more concern for sluffing on steep lee features. In addition, solar aspects will see avalanche activity during times of intense solar radiation. Be aware of overhead terrain.

    Pockets of soft slab are present in lee and cross-loaded features in the alpine. In many areas these new slabs sit on an old smooth layer of hard slab,and may be more likely to trigger where this condition exists.

Avalanche Summary

Sluffing in steep terrain continues on all aspects at all elevations up to size 2.0, more prominent on solar aspects.

Snowpack Summary

Variable new snow amounts of 4 to 8cm overnight. Moist snow on steep solar aspects. Storm snow totals are near 20 to 25cm. Variable wind affect in alpine features with some snow loading and soft slab development occurring in isolated terrain. Sluffing in steep terrain continues on all aspects at all elevations up to size 2.0.

Confidence

Fair - Timing, track, or intensity of incoming weather is uncertain

Light SW winds expected Tuesday with light precipitation. Alpine temperatures will reach -12. More significant precipitation amounts are likely on Tuesday night into Wednesday.
