Regions

Little Yoho.

We have moved to Low avalanche danger at all elevations in the Little Yoho area. This is because of a stronger snowpack in this part of our forecast region, and because we have not seen any avalanches release on a persistent weak layer here for weeks. But we remain sceptical of thin snowpack areas, so ease into it.

High

Avalanche Summary

No new avalanches have been observed or reported in this region for the past 72 hours.

Snowpack Summary

20-25 cm of soft, dry snow sits over the Feb 3 crust which exists in most locations (except high north aspects). This crust has helped to stabilize the snowpack, and at this time is not presenting as a weak layer of concern. This may change in the future if this crust deteriorates (facets), the wind picks up or the sun heats the snowpack. Persistent weak layers remain present in the mid and bottom of the snowpack but are not producing avalanches in deep snowpack areas at this time.

Weather Summary

A ridge of high pressure will dominate the region for the next several days bringing mostly blue skies, temperatures from -10 to -20 and light NE winds. No new snow is expected.

Terrain and Travel Advice

  • Avoid rock outcroppings, convexities, and anywhere the snowpack is thin and/or variable.

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.
