Regions: Glacier.

It's forecast to get real cold for the first time this year. Bring lots of extra layers, and leave yourself a time buffer at the end of the day, in case things go wrong.

Weather Forecast

Our first cold spell will bring generally stable weather for Sunday and into next week.

Tonight: Cloudy. Alpine low -17*C. Ridge top wind light-moderate W

Sun: Flurries/sunny periods. High -17*C. Light W wind

Mon: Sunny periods. Low -19*C. High -16*C. Light W wind

Tues: Sunny periods. Low -16*C. High -11*C. Light SW wind

Snowpack Summary

Another ~5 cm  of snow fell today.

At treeline and below, the Dec 1 crust is now buried by 5-20cm of snow.

In the alpine, 20-30cm of snow is being redistributed by light to mod West winds, and either lies on previous wind effect or icy bed surfaces from last weeks avalanche cycle.

The mid and lower snowpack is rounded and well bonded.

Avalanche Summary

One small avalanche was observed out of the cliffs on the North side of Cheops by a field team today.

The massive storm on Dec 01 produced widespread avalanches, both natural and artillery triggered, up to size 3.5, many reaching valley bottom. The frozen debris from these means travel in low elevation run-outs is rugged.

Avalanche Problems

Wind Slabs

Wind slabs may be found in exposed areas in the alpine. These overly previous wind effect or icy bed surfaces from previous avalanche activity.

  • Use caution above cliffs and terrain traps where small avalanches may have severe consequences.

Aspects: North, North East, East, South East, South, North West.

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2.5
