Avalanche Summary

No new avalanches have been reported in this region.

If you do go into the backcountry, please consider submitting a MIN report.

Snowpack Summary

Roughly 20 cm of new snow has buried a widespread, thick crust at higher elevations. New snow may not rapidly bond to the crust below.

At lower elevations, conditions remain rugged with a shallow snowpack and largely wet snow surfaces.

Weather Summary

Highest precipitation amounts are forecast for the west of the region, while lower amounts are forecast as you move eastward.

Terrain and Travel Advice

  • Closely monitor how the new snow is bonding to the crust.
  • Give the new snow time to settle and stabilize before pushing into bigger terrain.
  • Expect shallow snow cover that barely covers ground roughness.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
