Avalanche Forecast
Regions: Little Yoho.
Weather Forecast
Another storm will track through our region starting Wed night and will continue into Thursday. With this we can expect 25-35cm, strong W winds, and temperatures in the -8C range in the alpine. As the storm ends tomorrow, winds will shift to the East and diminish with a cooling trend.
Snowpack Summary
Storms from the last 7 days have deposited up to 70-80cm of snow. The main concern continues to be the 3 persistent weak layers of surface hoar and/or facets that are found between 50 and 150cm down in the snowpack. We continue to observe sudden test results, whumphing and large propagations on these layers.
Avalanche Summary
There have been large avalanches every day this week, mainly to size 3 with some larger. Most of these avalanches have been failing on the persistent layers mentioned above, with the odd avalanche going on the ground. Many close calls have been associated with these events.
