Regions

Little Yoho.

Winter returns! Snow moves into the region on Thursday and we may see up to 40 cm by Monday. See the forecast details for more information.

Weather Forecast

Snow moves into the region tomorrow with gusty strong SW winds. The forecast predict up to 10 cm per day for the next 4 days. Most of the snow will fall with light SW wind and moderate gusts for Friday and Saturday.

Snowpack Summary

Wind slabs up to 30cm's have been observed at TL and Alpine locations. The mid pack and base of the snowpack is well settled and well bonded overall. Surface crusts exist below 1900m

Avalanche Summary

No natural avalanches have been reported recently.

Confidence

Intensity of incoming weather systems is uncertain

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.
