Weather Forecast

SATURDAY NIGHT - Cloudy with isolated flurries, 2-4 cm / southwest winds, 30-50 km/h / alpine low temperature near -7SUNDAY - Mainly cloudy with scattered flurries / southwest winds, 10-30 km/h / alpine high temperature near -5 / freezing level 1700 mMONDAY - A mix of sun and cloud with isolated flurries / southeast winds, 10-20 km/h / alpine high temperature near -3 / freezing level 1900 mTUESDAY - Mainly cloudy with scattered flurries, 5 cm / west winds, 10-20 km/h / alpine high temperature near -1 / freezing level 1900 m

Avalanche Summary

On Friday, there were reports of a few size 1 human triggered storm slab avalanches.On Thursday, there were reports of a few natural, human and explosives triggered storm slab avalanches up to size 1.5, as well as a few size 1 loose wet avalanches.On Tuesday, there was a report of one size 2 natural loose wet avalanche on a south aspect at 2400 m.

Snowpack Summary

15-30 cm of recent storm snow sits on a melt-freeze crust on all aspects except for north facing slopes above 2000 m, where it sits on dry snow and surface hoar (feathery crystals). Recent snowfall amounts taper quickly below treeline.Snow is disappearing rapidly at lower elevations.

Avalanche Problems

Wind Slabs

Up to 30 cm of recent storm snow sits on a crust in most locations, and on dry snow on north facing alpine terrain. Strong southwest winds will have formed wind slabs at upper elevations.
Be careful with wind-loaded pockets, especially near ridge crests and roll-overs.

Aspects: North, North East, East, North West.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
