Weather Forecast
FRIDAY NIGHT: Clear skies, light northeast wind, alpine temperature -4 C, freezing level 1600 m.
SATURDAY: Clear skies, light north wind, alpine temperature -3 C, freezing level 1800 m.
SUNDAY: Mix of sun and clouds, light southwest wind, alpine temperature -2 C, freezing level 2000 m.
MONDAY: Cloudy with alpine flurries, accumulation 5 cm, moderate southwest wind, alpine temperature -2 C, freezing level 2000 m.
Avalanche Summary
A loose wet avalanche and cornice cycle occurred in the region during the storm on Thursday night and Friday, producing small to large avalanches (size 1 and 2). Most of the avalanches occurred in the alpine as well as treeline.
Snowpack Summary
Around 20 to 30 cm of recent snow has accumulated above around 2000 m. The snow fell with strong south wind, likely forming new wind slabs and cornices in the alpine. The snowpack below treeline is saturated and rapidly melting.
Problems
Wind Slabs
Wind slabs formed from recent snow and strong southerly wind may remain touchy this weekend. Be wary of the potential for these slabs when entering lee terrain features near ridges above 2000 m.
- Use small slopes without consequence to test the bond of the new snow.
- New cornices will be weak and could trigger wind slabs on slopes below.
- Be careful with wind-loaded pockets, especially near ridge crests.
Aspects: North, North East, East, West, North West.
Elevations: Alpine.
Likelihood
Expected Size
Loose Wet
Sunny skies on Saturday will likely cause the new snow above 2000 m to moisten and become touchy on sun-exposed slopes, increasing the potential for loose wet avalanches.
- Minimize overhead exposure and avoid steep slopes during periods of strong sun.
- Avoid terrain traps such as cliffs and gullies that increase the consequence of small avalanches.
Aspects: East, South East, South, South West, West.
Elevations: Alpine, Treeline.
