South Rockies

Wind slabs reactive to human triggers may be found on northerly aspects in the alpine.

Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.

No new avalanches were reported in this region on Thursday.

Data is limited in this region. Please consider posting your observations to the Mountain Information Network.

10 to 30 cm of recent snow overlies a crust on all but north facing aspects in the alpine.

A widespread crust with facets above is down 80 to 120 cm. Steep or convex terrain features with a shallow or thin to thick snowpack at treeline and above are the places where it may still be possible to trigger this layer with large loads.

Mostly cloudy with isolated flurries, 3 to 15 cm snow. 10 to 20 km/h west ridgetop wind. Treeline temperature -10° C. Freezing level valley bottom.

• Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
• Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
• If triggered loose wet avalanches may step down to deeper layers resulting in larger avalanches.
• Cornice failure may trigger large avalanches.
