Avalanche Forecast
Regions: Glacier.
Weather Forecast
A mix of sun and cloud today with nil precipitation, light northerly ridge-top winds, and freezing levels rising to 1900m. The clouds should dissipate by tomorrow as a ridge of high pressure sits down on the province. Freezing levels will spike well above 2000m by Wednesday as we prepare for the warmth of spring.
Snowpack Summary
~50cm of storm snow combined with sustained SW winds created a slab that is up to 1m deep on lee slopes. This slab overlies a crust on all aspects, providing a good sliding surface. Avalanches may step down to multiple crusts in the top metre. Overnight refreeze created a surface crust at lower elevations that is insulating ~40cm of wet snow.
Avalanche Summary
No new activity observed yesterday. However, warm temperatures over the weekend triggered wet point releases as well as a very large glide crack release (size 3.5). On Friday, a group of 5 accidentally triggered a size 3.0 avalanche on the steep roll on the Thorington line in the Asulkan Valley (NE asp, 2600m, 70m X 100m, 80cm deep on a crust).
Confidence
Due to the number of field observations
