Manage your exposure to overhead cornices and steep solar aspects when the afternoon sun shines. Have fun!
Summary
Weather Forecast
A high pressure ridge will keep the sun shining today and northerly winds will keep temperatures cool. Freezing levels are expected to stay below 1000m. A weak weather system will bring isolated flurries to the area late Sunday night and into Monday. Dry weather will prevail again early next week.
Snowpack Summary
Above 2300m, 10-15cm of ski penetration in soft snow. Snow depth on the Illecillewaet glacier/ neve is 2.5 to +3m. Bulletproof crust bellow 2000m. Feb 18 surface hoar down 20cm, variable distribution to 2200m. Feb 14 crust down 20-25, up to 10cm thick. Variable windslab above treeline. Persistent weak layers down 1-1.5m are stubborn to trigger.
Avalanche Summary
No new avalanches were observed yesterday. Recent natural avalanche activity has been limited to small skier triggered avalanches on isolated wind slabs and sun triggered loose avalanches on steep solar aspects.
Confidence
Problems
Persistent Slabs
There are several weak layers in the snowpack that are now difficult to trigger but may result in large avalanches if they do fail. Strong solar radiation or a large cornice failures are possible triggers.
Conditions are greatly improved, but be mindful that deep instabilities are still present.Carefully evaluate and use caution around thin snowpack areas.
Aspects: All aspects.
Elevations: Alpine, Treeline.
