    These slabs remain a concern on north aspects in the alpine where March winds built slabs over the facetted snow from February's cold snap. It is wise to check in on this layer now found 40- 70cm deep before venturing into committing terrain.

Weather Forecast

Strong winds clouds, cool temperatures and light precipitation are forecast. In the short term, expect an increase in windslab formation.

Snowpack Summary

10 to 30cm has fallen since April 9. the new snow is being pushed into small windslabs on lee N and E aspects. Facets 50 to 70cm deep produce clean, hard shears but have not produced an avalanche for a long time. Shallow bottomless facets can be found on high north aspects.

Avalanche Summary

A small skier triggered windslab was noted on the lee side of a ridgecrest today.
