The alpine rating is moderate, the treeline rating is low, and the below treeline rating is low. Known problems include Wind Slabs.

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

Summary

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

An icon showing Wind Slabs
Wind slabs exist at ridge-top and on cross-loaded alpine features. They sit atop a variety of surfaces and are most concerning on steep terrain where the consequences of even a small avalanche are high.
Be careful with wind loaded pockets, especially near ridge crests and roll-overs.Use caution above cliffs where small avalanches may have severe consequences.

Aspects: All aspects.

Elevations: Alpine, Treeline.
