    Watchout for warm temperatures over the next few days especially with the shallow snowpack. Small wet avalanches can be a problem if you are exposed ice climbing or above a terrain trap.

    This layer is most reactive where it has been loaded by wind transported snow. This problem includes the Oct 18 crust and the Nov 8th crust and surface hoar. There’s uncertainty around its distribution and triggerability.

Confidence

Moderate

Avalanche Summary

No new avalanches have been reported.

Snowpack Summary

10cm of moist surface snow to around 2200m due to above freezing temperatures. The Nov 8 crust and facets are down 20-30 cm at tree-line and below. We have also found surface hoar (6mm) down 60cm at 2500m. The October crust is widespread and is found near the base of the snow pack and has facets above and below. Snow depth is roughly 70 cm at treeline and tapers rapidly below.
