The snowpack is becoming more and more stagnant as we wait for more snow. The bulletins will be intermittent while we wait the early season dry spell out. Patience is the name of the game now...

Confidence

Good

Weather Forecast

The next few days will be much warmer than last week. Valley bottom temps will rise to 0 tomorrow and stay warm through out the evening and overnight. 3000m temperatures will also rise in the next 36hours. They may even hit 0 tomorrow afternoon. Winds will be light from the NW. No snow...

Avalanche Summary

No new avalanches

Snowpack Summary

Not a lot of change over the last two days, or the days to come from the looks of it. The crusts that formed in early Nov are still intact despite the cold temps. There is some question to the upper limits if this crust, but we expect it is up to atleast 2600m. Once travel improves, this will be nailed down a little better. On the crust there is 20-30 of loose, facetted snow at 2200m. Above 2200m there are isolated pockets of windslab, which could be easily triggered in the right terrain. Unsupported slopes should be treated with caution.

Avalanche Problems

Wind Slabs

These are isolated. Its thought they are more prevalent near ridge lines and open slopes on alpine faces where recent down flowing winds may have created slabs. Climbers should treat unsupported slopes with caution, especially if near a terrain trap.

Be careful with wind loaded pockets while approaching and climbing ice routes.>

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

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2

Loose Dry

The loose facetted snow will be easily triggered. A moving loose dry avalanche will likely entrain more snow than expected.

Avoid travelling on ledges and cliffs where sluffing may have severe consequences.>

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

Elevations: Alpine, Treeline.

Likelihood: Unlikely

Expected Size: 1 - 2
