    Main concern is for cross loaded gully features and steep rocky convexities on lee aspects where fresh windslabs are present.

    The weak lower snowpack is susceptible to triggering in lee areas that have been recently loaded by SW winds and last week's snow.

Weather Forecast

No new precipitation on the horizon. Mild temperatures with calm to light Northerly winds. Sunny and clear.

Snowpack Summary

Last week's 20-30cm of rapidly settling and wind distributed storm snow overlies facets and basal weakness. New reactive windslabs in lee gully features and especially on NE aspects. Extensive scouring of last weeks snowfall at and above treeline.

Avalanche Summary

Good results (several size 2 to 2.5 in steep rocky alpine terrain) in recent explosive control work at Marmot ski hill, suggests that the weak basal layer is reactive to large loads. No patrol in the Columbia Icefield area today.
