Regions: Glacier.

Weather Forecast

The ridge of high pressure will continue to steer any significant weather away from the region. Today and Friday we will see increasing cloud with potentially a few flurries. Accumulations will be a few centimeters a day. Alpine highs will be -4'C with moderate ridgetop winds. Saturday will be similar but with sunny periods.

Snowpack Summary

~5cm of snow covers the previous surface of crust, facets, surface hoar and pockets of thin soft slab. Northerly winds have created pockets of soft slab in the immediate lees of ridges. Overall the snowpack is now well settled and strong.

Avalanche Summary

Small pockets of windslab have been reactive to skiers at ridgetop and the loose surface snow sluffs on steep slopes. No new natural avalanches have been observed recently.

Avalanche Problems

Wind Slabs

Northerly winds early this week created isolated wind-slabs in unusual places. Small pockets of wind-slab have been reactive on steep lee features. These are of most concern on steep, aggressive terrain where the consequences of a fall are severe.
Use caution in lee areas in the alpine. Recent wind loading have created wind slabs.Travel conditions are difficult at lower elevations and in the trees.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 2
