Regions

Glacier.

Watch for thin slabs in isolated lee features. They have the potential to push a rider over cliffs in a "no-fall" zone.

Weather Forecast

Another cold, clear day with light to moderate winds from the north and east. Bundle up and keep moving...

Snowpack Summary

5-10cm of soft snow overlies hard snow surfaces of sun crust on steep solar aspects and wind slab at higher elevations. This new snow has seen some wind affect and is slow to bond to the underlying layers due to cold temps. A new surface hoar layer is down 5cm at lower elevations. The mid pack is well settled. Cold weather is faceting the snowpack.

Avalanche Summary

No new avalanches observed yesterday.

Confidence

The weather pattern is stable

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind 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.
