Points saillants

A warm front on Wednesday will possibly bring freezing levels up to 2000m, strong winds, and some new snow. This may test our existing problems especially at lower elevations.

    Variable windslabs continue to develop from moderate-strong gusting winds. These slabs appear unreactive with relatively little natural activity yet assume touchy pockets exist such as steep gullies or unsupported slopes. Choose conservative tracks.

    On Sunday, large cornice drops triggered this layer proving the lurking danger of this weakness. Full path avalanches remain possible. Caution initiating the windslab problem that could step down.
