Summary
Confidence
Poor - Due to limited field observations
Weather Forecast
Saturday & Sunday: Cool and dry, with temperatures reaching -10 and Easterly winds easing to calm. No precipitation. Monday: Clouds developing with a chance of flurries later in the day. Winds turn Westerly but remain light.
Avalanche Summary
Observations are extremely limited at this time. No new avalanches have been reported.
Snowpack Summary
Up to 15cm of new snow has fallen in the last 24hrs. Snowpack depths are likely in the 60-80cm range at about 1600m and about 125cms at 2000m. In the upper snowpack, windslab and storm snow instabilities exist within previous accumulations of up to 80cms+. Watch for the possibility of reverse loading with the recent Easterly winds. There's bound to be variability throughout the region and one slope/mountain/drainage may differ significantly from the next. A conservative approach combined with careful investigation of local conditions is advised until we get a better understanding of conditions.
Problems
