Weather Forecast

SATURDAY NIGHT: Cloudy with clear periods, light southeast wind, alpine temperatures drop to -12 C.SUNDAY: Mix of sun and cloud in the morning and clearing in the afternoon, light northeast wind, alpine high temperatures around -10 C.MONDAY: Sunny, light northeast wind, alpine high temperatures around -12 C.TUESDAY: Sunny, moderate northeast wind, alpine high temperatures around -15 C.

Avalanche Summary

No new avalanches were reported at the time of publishing on Saturday.On Friday, skiers triggered several small (size 1) slab avalanches at upper treeline elevations and in lee alpine terrain. A few small loose dry avalanches were observed on south-facing slopes when the sun came out in the afternoon.

Snowpack Summary

20 cm of low density snow sits above sun crusts on south-facing slopes and hard wind affected snow in the alpine. Deeper deposits may be forming in wind-affected alpine terrain. In sheltered areas, 20 to 40 cm of low-density faceted snow is gradually settling onto old hard surfaces including crusts and wind-packed snow. Low-density snow may sluff easily on these hard surfaces. The lower snowpack is strong and settled.

Avalanche Problems

Storm Slabs

Storm slabs may be possible to trigger at higher elevations, especially in wind loaded pockets.

Use caution above cliffs and terrain traps where small avalanches may have severe consequences.Be careful with wind loaded pockets, especially near ridge crests and roll-overs.Minimize exposure to steep, sun exposed slopes when the solar radiation is strong.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 1.5
