Not a great start to the winter right now.  Skiing opportunities are limited but travel into ice climbs is great!  We need about 40cm of snow to improve the skiing.

Summary

Confidence

Good

Weather Forecast

We may see up to 8cm of new snow over the next 48hrs.  Not enough to improve the skiing.

Avalanche Summary

No new avalanches were observed.

Snowpack Summary

Hard slabs overlying a weak facetted base is the main theme of the day.  With the warm temps, there may be some surface crusts at lower elevations on solar aspects.  Any avalanche that initiates is likely to involve the entire winters snowpack.

Problems

Persistent Slabs

An icon showing Persistent Slabs
Any avalanche that initiates is likely to involve the entire winters snowpack at this time due to stiff nature of the overlying slab and facetted base.
Avoid thin, rocky or sparsely-treed slopes.>Be aware of thin areas that may propogate to deeper instabilites.>Be aware of the potential for full depth avalanches due to deeply buried weak layers.>

Aspects: All aspects.
