Regions: Glacier.

Isolated wind slabs and the potential for solar-triggered avalanches require good spatial awareness today.

Weather Forecast

Sunny with cloudy periods and no precipitation today. Alpine temperature will reach -7 C with freezing level rising to 1200m. Expect light ridge wind.

A cold front arrives on Saturday bringing the next bout of precipitation. We are expecting 15cm of new snow for the weekend and gusty SW winds.

Snowpack Summary

There is 20-30cm of low density snow over a well settled mid-pack. Variable stubborn wind slab may be found in alpine elevations along ridge-tops and exposed tree-line features. Steep S to SW aspects have a suncrust buried anywhere between 30-60cm below the surface.

Avalanche Summary

No new avalanches were observed or reported yesterday.

Avalanche Problems

Wind Slabs

New snow accompanied by recent moderate westerly winds has created wind slabs in isolated locations. Slabs were observed this week at ridge-top areas and on exposed, cross-loaded slopes.

  • Use caution in lee areas. Recent wind loading has created wind slabs.
  • Watch for signs of instability such as whumphing and cracking.

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

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 2.5

Loose Dry

If the sun stays out today, loose dry avalanches may be initiated on steep SE-W aspects and around rocky features.

  • Minimize exposure to steep, sun exposed slopes when the solar radiation is strong.

Aspects: South East, South, South West, West.

Elevations: All elevations.

Likelihood: Possible - Likely

Expected Size: 1 - 1.5
