Regions

Glacier.

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.

Confidence

High

Avalanche Summary

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

Snowpack Summary

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!

Weather Summary

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

Terrain and Travel Advice

  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
  • Avoid travelling on slopes below cornices.

Problems

Loose Dry

Loose Dry avalanches are the release of dry unconsolidated snow and typically occur within layers of soft snow near the surface of the snowpack. These avalanches start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-dry avalanches include point-release avalanches or sluffs.
