20cm of new snow Friday night with strong winds created wind slabs on many ridgetop features. Be cautious of local wind influences where reverse or cross loading may have occurred.
20-30cm of new snow will require a day to bond and settle. Be patient.
The new snow has enough mass to warrent this problem. Give it a few days to settle particularly in steep gullies.
Deep persistent slabs are best managed by:
Cornices are best managed by:
Sunday will be cloudy, flurries, -11 C, and light SW winds. Monday will be flurries, 6cm of snow, -13C, and light SW winds gusting to 50km/hr. Tuesday will be sun, no snow, -15C and light West winds.
Friday night there was 20cm of new snow and strong Westerly winds. A lot of snow got whisked away in exposed locations and powder settled into sheltered locations. The snowpack remains highly variable with either soft or wind effected surface snow. Parkers weather plot has 101cm. A crust from Nov 4 is 70cm deep and found up to 2600m.
Saturday's explosive control at Parkers slabs resulted in two size 2.5 avalanches from the wind loaded storm snow. A few other thin slabs were noted in steep alpine terrain. The visibility was good.
