Regions

Little Yoho.

Avalanche control is being conducted in the Bourgeau slide paths tomorrow. No activities in this location during this time. However, in all other locations, new snow has refreshed the ski quality. Be on the lookout for wind slabs.

Weather Forecast

A stable weather patter with light wind, clearing skies and next to no precipitation will allow for the danger ratings to remain level. The next precipitation is forecasted for early on Wednesday.

Snowpack Summary

10 to 20cm of low density snow has fallen over the forecast region. Little wind accompanied the storm. This new snow has improved ski quality but has buried wind slabs that were formed by strong wind in the last few days. Use caution in areas that have seen previous wind affect.

Avalanche Summary

No avalanches observed or reported today.

Confidence

Wind effect is extremely 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.
