No new avalanches were reported over the past few days.

A new melt-freeze crust is expected on solar aspects into the alpine and all aspects at lower elevations. This crust will likely break down and become moist as the sun comes out. Ongoing periods of strong westerly winds have formed wind slabs and large cornices in exposed terrain at higher elevations. 

The January 30 interface is now typically down around 20cm and consists of a variety of forms including surface hoar, facets and a crust. It is generally only concerning in the north part of the region. The mid January crust is down 20 to 70 cm deep. In most of the region this crust may only be found on solar aspects. In heavily wind effected areas it may be found on the surface.

The early December crust/facet persistent weak layer is now 100-200 cm deep. This layer produced numerous very large avalanches in January but is now considered dormant. See this forecaster blog on how to manage this layer as it may come into play again later this season. 

• Be careful as you transition into wind affected terrain.
• Cornices become weak with daytime heating or solar exposure.
• Avoid steep slopes when air temperatures are warm, or solar radiation is strong.
