Regions: Little Yoho.

Watch for new windslabs as you approach or enter lee areas near ridgecrests. Watch for loose snow in gully features.

Weather Forecast

Forecasted precipitation beginning Saturday with accumulation values ranging from 15-20cm by Monday. Winds will be moderate to strong from the south west, expect snow transport and windslab development.

Snowpack Summary

20-50cm of snow sits over the december 15 surface hoar layer which is beginning to develop some slab properties. Below this the snowpack is heavily faceted with remnants of older crusts still lingering throughout. In many areas loose faceted surface snow continues to be the main instability in the snowpack.

Avalanche Summary

No new avalanches were noted today.

Avalanche Problems

Loose Dry

Loose snow will continue to be a problem in steep rocky areas and gullies until the facets round out a bit.
The volume of sluffing could knock you over; choose your climb carefully and belay when exposed.Avoid ice climbs exposed to steep rocky terrain on solar aspects during the middle of the day.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 2

Wind Slabs

Previous new snow is being moved by the chinook winds, continuing snowfall and wind over the next few days will likely make the problem worse.
Use caution in lee areas. Recent wind loading has created wind slabs.Watch for surface cracking and stiffer surface layers of snow. Avoid wind loaded terrain.

Aspects: North, North East, East, South East.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 3
