Regions: Little Yoho.

Heads up skiers and climbers! With fresh snow and winds the Dec 15 layer will soon wake up. Pay attention to new snowfall amounts and fresh wind slabs.

Weather Forecast

Cooling trend with up to 10 cm new snow at tree-line and moderate SW winds forecasted for Wednesday. High pressure ridge will start to rebuild over area on Friday.

Snowpack Summary

40-50cm of snow sits over the Dec 15 layer which consists of surface hoar, sun crust, or facets depending on location. Easy to mod shears found on this layer. Below this the snowpack is heavily faceted with remnants of older crust's still lingering throughout, but no significant shears found in the lower pack. Some isolated windslabs near ridgetop.

Avalanche Summary

No natural avalanches observed or reported in past 24 hours.

Confidence

Avalanche Problems

Wind Slabs

Recent snow is being moved around by the SW winds and forming fresh wind slabs in lee alpine areas. These slabs can fail on the the Dec 15 layer which is producing easy to moderate shears.
Use caution in lee areas. Recent wind loading has created wind slabs.

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

Elevations: Alpine, Treeline.

Likelihood: Likely

Expected Size: 1 - 2

Loose Dry

Loose dry surface snow avalanches will continue to be a problem in steep rocky areas and gullies.
On steep slopes, pull over periodically or cut into a new line to manage sluffing.The volume of sluffing could knock you over; choose your climb carefully and belay when exposed.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 2
