    The basal facets are producing large destructive slab avalanches that are failing on the basal facets.

Weather Forecast

Well here comes another blast of winter.  Up to 50cm of new snow is expected over the next few days with freezing levels around 2300m.  This lack of freeze at lower elevations will trigger another round of natural avalanche activity at lower elevations on all aspects.  THe next few days will not be the time to get out skiing.

Avalanche Summary

Lots of loose wet, and wet slabs up to sz 3 have been observed over the past 24hrs. THese slabs have been occuring on all aspects and failing down to ground in many areas.

Snowpack Summary

The warm temps are starting to penetrate deeper into the snowpack.  Isothermal snow is now being found up to treeline in some areas.  Above this, expect to have surface crusts that break down later in the day resulting in some corn snow,  Remember though what goes up must come down and you dont want to be wading through isothermal snow back to the trailhead.
