Pay attention to changing conditions as we transition to a spring snowpack in the Alpine.
Expect cold and (slightly) snowy conditions Tuesday morning with rapidly rising temperatures later in the week.
A dusting of new snow is expected overnight on Monday. New snow will fall over a very firm crust, making it easy to start small loose dry avalanches in steep terrain.
Loose wet avalanches up to size 2 were observed the over the weekend from steep, rocky, S-facing slopes in the alpine. No new avalanche activity reported on Monday.
Neighboring operations also observed solar triggered loose snow avalanches out of steep terrain over the weekend, up to size 2.
Natural cornice failures have been observed up to size 2.5
A few centimetres of snow is forecast overnight on Monday. This dusting of new snow will sit over a firm crust everywhere except high north alpine slopes, where settled powder can still be found.
Expect poor travel conditions below treeline. Height of snow at Rogers Pass (1305m) is ~50cm, and even shallower on solar slopes!
A weak frontal system moves in Monday evening bringing a small amount precipitation.
Tonight Scattered flurries, ~5 cm. Wind SW 25 km/h. Freezing level (FZL) 1700m.
Tues Sun and cloud with isolated flurries. Trace precip. Alpine high -2 °C. Wind W20-40 km/h. FZL1900m
Wed Mix of sun &cloud. No precip. Alpine high 2 °C. Wind W-25 km/h. FZL 2300m
Thurs Mix of sun & cloud. No precip. Alpine low 1°C. Wind SW 10 km/h. FZL 3400m
