Kernpunkte

Strong winds will conspire to keep danger ratings in alpine terrain at Considerable for another day or two.  Rising temperatures as the week moves along mean it may become necessary to keep a watchful eye on solar aspects for concerns.

    Soft slabs are prominent at treeline and have become more sensitive to human triggering in the past 24hrs, especially in lee and cross-loaded features just below ridgeline. Alpine areas are scoured with areas of hard slab and soft slab.

    Buried wind slabs (originally formed in late January) are still are concern in steep features in the alpine and at treeline. These slabs are found down 30 to 60cm in the snowpack and are likely more trigger-able from shallow snowpack areas.

Confidence

Fair - Due to variable snowpack conditions

Weather Forecast

Only a couple of centimeters of new snow is expected over the next 24 hours and only dribs and drabs over the remainder of the week.  Winds are expected to remain in the moderate to strong values range.  Temperatures will rise as the week progresses.

Avalanche Summary

A few loose dry sluffs from extreme lee aspects.  No other natural avalanche activity observed.

Snowpack Summary

Some redistribution of loose snow in all elevation zones with fresh slabs continuing to develop on lee aspects
