Points saillants
As the temperatures warm, the snowpack should gradually become more stable except on sun exposed slopes. It may still be too early to commit to the large consequence lines.

There have been a number of cornice falls observed over the last week, some triggering deep storm slabs beneath. Be aware of what is above you.

Watch out for thin areas especially East of the divide where it is possible to trigger or remote trigger deep slabs on basal facets or crusts.? Be conservative with terrain choices in bigger terrain.
Weather Forecast
Another fine cool day with the chance of some high cloud in the afternoon as a weak fontal system rides over the ridge.
Snowpack Summary
Some wind slab and cornice issues in the westerly areas. Deep slab persistent weak layer concerns in the eastern shallow snowpack areas. In areas of 170cm or deeper snowpack the snow seems mainly stable, with a few isolated exceptions at and above treeline on lee slopes. East of the divide where the snowpack was less than 150cm, beware.
Avalanche Summary
Several cornice falls over the past few days have triggered storm slabs up to size three. Remote triggered deep slabs have been reported in eastern areas.
Confidence
