Avalanche Forecast
Regions: Little Yoho.
Weather Forecast
Valley bottom temperatures will drop Saturday night with a slight inversion forecast for Sunday, alpine temps expected around -12 to -17. A brief break in precipitation Sunday will bring clears skies before another small system moves in Monday. Winds are expected to remain in the light to moderate range through Sunday.
Snowpack Summary
25-40cm of new snow and moderate winds have developed new storm slabs in the upper snowpack. The main concern in the snowpack continues to be the three persistent weak layers of surface hoar and/or facets that are found between 50 and 100cm down. We continue to observe sudden test results, whumphing and large propagations on these layers.
Avalanche Summary
Lake louise ski patrol reported numerous natural and skier triggered avalanches in the recent storm snow with one large explosive result stepping down to a persistent weak layer (size3). We have seen big natural avalanches over the last few days as the snowpack remains prime for triggering.
