Small amounts of new snow are expected by midweek. Not enough to significantly elevate the hazard but hopefully enough to replenish the ski surface. Believe.

Summary

Weather Forecast

Up to 10cm of snow is expected late on Tuesday. Until then, expect the current weather pattern to persist.

Snowpack Summary

Despite the presence of weak facets and depth hoar near the ground, the weak layers in the snowpack are largely dormant right now. Once the temperatures warm up significantly and/or new snow arrives then the weak layers may re-activate. Hard windslabs were found near Sunshine Village today. Snowpack tests produced hard results.

Avalanche Summary

No new avalanches reported or observed today.

Confidence

Problems

Deep Persistent Slabs

The lower half of the snowpack is weak due to the presence of basal facets and depth hoar. Natural and human triggering is unlikely as the weak layer is dormant, but it is still a good practice to avoid steep, open, rocky slopes with shallow snow.

Travel conditions are difficult at lower elevations and in the trees.Ski crampons make travel easier and safer on frozen surface conditions
