Regions

Glacier.

Human triggered avalanches are certainly possible on steep and exposed terrain. Expect avalanche hazard to increase with solar input and building winds.

Weather Forecast

A mix of sun and cloud today with and Alpine high of -4.  Ridge wind will be SW 35 km/h with the freezing level rising to 1200m. No precipitation is expected until tomorrow morning, when a low pressure system will arrive spreading 4cm of accumulation.

Snowpack Summary

It has been over a week since the last significant snowfall but settled powder remains in sheltered areas. A sun crust is present on steep solar aspects with a variable wind slab at ridge crest and in cross loaded areas. Storm interfaces down 25-40cm are bonding but still producing planar results in stability tests.

Avalanche Summary

No new avalanches were observed yesterday.

Confidence

Intensity of incoming weather systems is uncertain

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.
