Spring is a time when weather and conditions can be highly variable. Visit the latest Avalanche Canada Forcasters Blog for resources and tips to help navigate the switch to spring.

Avalanche Summary

No new avalanches observed or reported.

If you have any recent observations, please submit them to the Mountain Information Network.

Snowpack Summary

5-10cm of new snow has fallen on a surface crust that exists up to 2200m all aspects. Above 2200m 10-15cm dry snow sits on a supportive crust that exist up to 2600m on all aspects, and to mountain top on solar slopes. Strong upper and mid-pack, supportive to skis and boots. Lower snowpack consists of basal depth hoar.

Terrain and Travel Advice

Be carefull around freshly wind loaded features.

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.

Loose Dry

Loose Dry avalanches are the release of dry unconsolidated snow and typically occur within layers of soft snow near the surface of the snowpack. These avalanches start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-dry avalanches include point-release avalanches or sluffs.
