Snow seems generally stable after recent melt-freeze cycles. Wind slabs are likely to form in snow showers over the weekend but directions shift from S to N on Sunday. Old weaknesses may still exist at some locations.

The avalanche bulletin is at a regional scale. It does not necessarily represent avalanche danger in urban areas.

Avalanche problems in the area

Unlikely that depth hoar is still present but possible high in the mountains where warming may have impacted the snow pack less.

Snow layers and snow cover

Snow is considered rather stable after melt-freeze cycles. New wind slabs have formed in S and W winds on Friday and Saturday and they might be unstable. On Sunday the winds shift to the N an wind slabs can be expected to form on S aspects in significant snow showers. Old weak layers, which the thaw has not broken down, may though still exist in certain places. It is unlikely to trigger avalanches on this layer, but if it happens, the avalanches can be large.

Recent avalanches

No avalanches have been reported since the thaw last weekend.
