Avalanche Canada
The cooling has kept most of the region in an 'All Freeze, No Melt,' scenario. Spring convective activity continues to deliver variable amounts of new snow to the region.

Avalanche Summary
The cooling has kept the region in an 'All Freeze, No Melt,' scenario, with no new avalanche activity observed or reported.
Don't forget to post avalanche observations to the MIN.
Snowpack Summary
A dusting of snow, on top of a sun crust at all elevations on solar aspects, with mixed facets on polar aspects. The mid-pack consists of multiple layers of dense wind-affected snow, sun crust, and facets. Depth hoar and basal facets make up the base of the snowpack. Snow depth varies ranges from 60-170cm.
Weather Summary
Little change is expected in the weather. Light variable winds may transport new snow from convective flurries. Freezing levels to rise daily up to 1500m. Temperatures are expected to be seasonal with cold nights and a daytime high of -7 C in the alpine.
Terrain and Travel Advice
- When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
- Use caution on large alpine slopes, especially around thin areas that may propagate to deeper instabilities.
Problems
Deep Persistent Slabs
The bottom of the snowpack is inherently weak with well-developed Facets and Depth Hoar. Large triggers like cornices can still initiate this deep persistent slab so be mindful of your overhead hazard and keep in mind that human triggering remains possible in thick to thin snowpack areas.
Aspects: All aspects.
