    Solar aspects are susceptible to increasing avalanche danger each day as solar radiation and warm temperatures affect the snowpack. Plan your day to avoid exposure to large sunny slopes in the afternoons.

Avalanche Summary

Numerous sluffs up to size 1.5 in the past 24 hours. A few slab avalanches up to size 2.0 have also been observed in last 24-48 hours. Most avalanches are occurring on steeper slopes in the alpine, some on N and E aspects and solar triggered slides on the southerly aspects.

Snowpack Summary

5 to 20cm of recent storm snow fell on previously formed crusts. Buried crusts are present on all aspects except above 2100m on N aspects. Moist snow today on solar aspects in the afternoon which will form new surface crusts overnight.

Confidence
