Regions: Glacier.

Look to alpine north aspects for the best ski quality. Solar aspects will likely be crusty and  crunchy.

Weather Forecast

Cloudy with 4cm of snow and an alpine high of -6C. Ridge winds should remain light and freezing level is forecast to reach 1500m. The start of the new week calls for cloudy with sunny periods and isolated flurries. Alpine temperatures are expected to remain cool and be accompanied by light westerly winds.

Snowpack Summary

The snowpack is generally well settled. 5-10cm of recent moist snow has now frozen into a breakable crust below treeline. Above treeline this new snow remains dry and unconsolidated burying a previous melt freeze crust that extends up to 2300m on all aspects and to mountain top on solar aspects. Cold dry snow may be found on high northerly aspects.

Avalanche Summary

Limited natural avalanche activity over the last couple days with one glide crack release size 2 on Friday. Previously we've seen numerous loose wet avalanches on steeper solar aspects. If the sun does appear move off steeper solar aspects.

Confidence

Timing or intensity of solar radiation is uncertain

Avalanche Problems

Loose Wet

Cloud cover today should reduce the chance of loose wet slides on solar aspects. However if the sun does come out expect the recent 5-10 cm of snow to become reactive around rocks and trees on steep solar terrain.
Use caution above cliffs where small avalanches may have severe consequences.

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

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2
