In sintesi

Surprisingly little avalanche activity as a result of the significant amount of storm snow received this past week. Uncertainty remains on how reactive this new snow will be to human traffic. Conservative terrain choices are recommended

    Surprising little avalanche activity on this layer. Uncertainty related to how sensitive this problem will be to human triggers

    Dry loose and storm slab avalanches may step down to weak layers close to the ground producing large avalanches

Avalanche Summary

Surprising little avalanche activity in the last 72 hours given the amounts of storm snow that has fallen on the forecast area in the last week. A new size 2 wind slab out of northerly treeline lee feature and some dry loose up to size 2 out of steep alpine terrain were the only new avalanches in the last 24 hours.

Confidence

Due to the number of field observations on Monday

Weather Forecast

Clear skies and calm winds will continue through Tuesday. Tuesday night winds will increase from the NW and continue through to later in the week.

Snowpack Summary

45cms of mostly undisturbed HST continues to settle and with cold temperatures tighten up. This overlies a mosaic of buried wind slab, ground and facetted weak layers. Basal layers continue to develop into larger facets and depth hoar. Surface hoar continue to grow in sheltered areas.
