Avalanche Summary
At the time of publishing, no new avalanches were reported in the past 5 days.
Snowpack Summary
Up to 15 cm of new snow may accumulate by Sunday morning. This new snow will be accompanied by moderate southerly winds forming wind slab on north aspects. In sheltered terrain this new snow may overlie soft, faceted snow or surface hoar. In exposed terrain it will overlie a sun crust or wind-affected snow.
A weak layer from late January, buried 40 to 60 cm deep, is a hard crust in many areas but consists of facets or surface hoar on sheltered upper-elevation slopes. This layer has become reactive in snowpack tests.
A crust from December is buried 80 to 120 cm deep, with facets around it in shallow snowpack areas. Otherwise, the lower snowpack is strong and bonded.

Terrain and Travel Advice
- The best and safest riding will be on slopes that have soft snow without any slab properties.
- Be careful as you transition into wind-affected terrain.
- Closely monitor how the new snow is bonding to the old surface.
- Use ridges or ribs to avoid areas of wind-loaded snow.
Problems
Wind Slabs
Newly formed wind slabs could be found in exposed terrain. These slabs may be touchy due to the weak layers underneath.
