Lo esencial

Good skiing can be found in most places.  Be aware of new wind slabs in isolated areas in the alpine. Ice climbers should be aware of loose dry avalanches in gullies.

Weather Forecast

Monday is forecast to bring cloudy skies, sun and isolated flurries.  Alpine temperature will be -13c with westerly ridge winds of 25-35km/h.

Avalanche Summary

The following was observed:1.  One natural size 2.5 slab in the Commonwealth area2.  One size 2.5 slab in the Goat Range3.  Several loose dry avalanches up to size 2

Snowpack Summary

25-40cm of snow has fallen since Friday.  In the tree elevations, this storm snow is laying on top of a weaker snowpack.  Some soft slab development has occurred in the alpine but is isolated for the time being.  If the winds pick up and start to move the snow around, the wind slabs will develop and the hazard will increase in the alpine and open areas.
