    An increasingly well settled snowpack means triggering an avalanche on a deep persistent layer has become unlikely. However, large and destructive avalanches may be possible with a heavy load in steep, thin start zones.

Weather Forecast

Cold and dry for the next few days with no new snow expected. A light northerly flow but mostly light to nil winds. Wednesday and Thursday we may have a few hours of nice sunshine and temperatures moderating later in the forecast period.

Snowpack Summary

15cm of new snow in the past week. Minimal wind effects observed. Cool temperatures have helped strengthen the snowpack.  Test results below treeline Monday showed sluffing potential in steep open areas. Most deeper snowpack areas bridge the  lingering basal weakness.

Avalanche Summary

no new avalanche activity observed
