Recent winds have left behind wind slabs on lee slopes. Keep track of where you are in the terrain to avoid these areas.

Moderate - Intensity of incoming weather systems is uncertain

On Sunday, several explosives-triggered avalanches to size 2 were reported in the region at or near treeline on all aspects.

25-40 cm of recent snow has fallen in the region. Moderate to strong winds have promoted widespread slab formation. The storm snow sits on several layers of small surface hoar (feathery crystals) and thin crusts. Recent snowpack tests suggest the snow may be poorly bonded to these layers in some areas. The most prominent weak layer in the snowpack is a layer that formed in early December and is buried approximately 70-120 cm. This layer consists of a rain crust, surface hoar, and facets (sugary snow). There have been no recent reports of avalanches on this layer, however a large load such as a cornice fall may still have the potential to trigger large avalanches on this layer.
