Recent snow and southerly wind may have formed fresh wind slabs on lee features in the alpine.

Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.

No avalanches were reported on Sunday. However, observations in this region are currently very limited.

Observations are limited at this time of year, please consider sharing any information or photos you have on the Mountain Information Network to help guide our forecasts.

Recent snow and southerly wind may have formed fresh wind slabs on lee features in the alpine.

Cornices are very large and loom over slopes below like gargoyles. Cornice falls may trigger large avalanches on the slopes below.

A robust crust exists on all aspects up to approximately 1400 m and to ridgetop on sunny aspects.

A weak layer of surface hoar/crust/facets buried in early January is now around 100 cm down in most areas. A significant warming event or a large trigger (like a falling cornice) are the most likely things to activate this layer.

• Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
• Wind slabs may be poorly bonded to the underlying crust.
• Pay attention to cornices and give them a wide berth when traveling on or below ridges.
• Cornice failure may trigger large avalanches.
