Storm slabs will likely continue to be reactive, especially in wind loaded areas.
Although the storm has subsided, human triggered avalanches remain likely, especially in wind loaded areas.
Keep in mind that a persistent weak layer is now buried up to 60 cm. Avalanches on this layer will become harder to predict, so a conservative approach is important.
Storm slabs will likely continue to be reactive, especially in wind loaded areas.
30-60 cm sits on a buried weak layer that consists of facets, surface hoar, or a crust, depending on location. Avalanches on this layer may propagate widely.
TUESDAY NIGHT - Mainly cloudy with a few flurries / moderate southwest wind, switching to light northwest wind overnight / alpine low temperature near -11
WEDNESDAY - Sunny with cloudy periods / light north wind / alpine high temperature near -10
THURSDAY - Mainly cloudy with a few flurries, 5-10 cm / strong west wind / alpine high temperature near -7
FRIDAY - A mix of sun and cloud / moderate northwest wind / alpine high temperature near -6
Human triggered avalanches will remain likely on Wednesday, especially in wind loaded areas at higher elevations.
There were several reports of size 1-2.5 natural, human and explosives triggered avalanches in the region on Monday. It is suspected that some of these failed on the recently buried persistent weak layer.
There were several reports of size 1-1.5 natural and human triggered avalanches in the region on Sunday.
30-60 cm of recent fresh snow sits on a persistent weak layer that consists of facets at upper elevations, surface hoar in sheltered areas, a melt-freeze crust below 1600 m, and a sun crust on south-facing slopes.
In the south, the underlying snowpack is well consolidated. In the north, a melt-freeze crust from early December may be found 100 to 200 cm deep. Recent reports suggest that this layer is gaining strength and it has been unreactive in recent weeks.
