Regions

Little Yoho.

We are pressed under a cold Arctic airmass with rock bottom temperatures. Consider the risk of prolonged exposure in the event of even a small incident and plan accordingly.

Confidence

High

Avalanche Summary

No avalanches were observed reported today.

Snowpack Summary

25-30cm of settled storm snow from last week has been redistributed by the wind in exposed locations, burying the Jan 30 weak layer. The mid and lower snowpack is well settled, with tree-line snow depths ranging from 120 cm to 180 cm.

Weather Summary

Tomorrow's temperatures will remain as cold as today, with only a gradual warming trend through the coming week. The wind will stay light from the North, maintaining the influence of the Arctic air mass. No snow is expected, though some cloud cover may develop in the afternoon.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Wind slabs are isolated, but may remain reactive.
  • Closely monitor how the new snow is bonding to the old surface.

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.
