Avalanche Forecast
Regions: Glacier.
Remember that there has not been a melt-freeze cycle at higher elevations as you transition into the alpine, stay well back from cornices, and avoid windloaded pockets when entering slopes.
Weather Forecast
A brief bout of high pressure gives relatively stable weather and cold temps until mid week.
Today: Mainly sunny. Treeline temps High -15 C. Light SW ridge wind.
Tonight: Clear periods. Treeline temps Low -18 C. Light SW ridge wind.
Tuesday: Cloudy with isolated flurries. Treeline temps -13 C. Light W wind.
Snowpack Summary
We received 15-20cm of low density snow in the wake of Saturdays storm. This sits on firm surfaces from the Extreme winds, 70mm of precip, and 2000m freezing level mid storm. Expect rugged travel in all but smooth open slopes below treeline - with 10-15cm of snow on a crust- and pockets of windslab in lees at treeline and in the alpine.
Avalanche Summary
No new avalanche activity was observed or reported locally yesterday.Â
A widespread cycle of large to very large natural avalanches occurred during Saturdays storm. Avalanche control using artillery produced numerous size 3-3.5 avalanches from all aspects.
Confidence
Due to the number of field observations
Avalanche Problems
Wind Slabs
Fresh pockets of soft windslab that formed late in the storm linger on lee slopes. The deep and stiff widespread windslab that formed mid storm is generally unreactive, but may remain sensitive to large triggers like cornices in the alpine.
Aspects: North, North East, East, South East, North West.
Elevations: Alpine, Treeline.
Likelihood: Possible
Expected Size: 1 - 2
Cornices
Cornices grew significantly Saturday and deserve a wide berth. Stay well back from corniced ridges.
- Minimize exposure to corniced features.
Aspects: North, North East, East, South East, West, North West.
Elevations: Alpine, Treeline.
Likelihood: Possible
Expected Size: 1 - 2
