Regions

Kananaskis.

Bulletins will be issued intermittently for the remainder of the season. Spring conditions - pay careful attention to the destabilizing effects of solar radiation and daytime heating. Time your trip accordingly.

Confidence

Good

Weather Forecast

Freezing levels will rise to at least 2000m on Thursday under a mix of sun and cloud. Temperatures should reach -6 in the alpine and a trace of precipitation is expected overnight. Winds will be moderate form the NW.

Avalanche Summary

Numerous sluffs on S and SW aspects up to size 1.5. One size 2.0 naturally triggered slab at 2300m on a N aspect in the Goat Range.

Snowpack Summary

Moist snow on steep solar aspects. Wind slabs are still present in lee and cross-loaded terrain in the alpine. Previously formed crusts persist.

Problems

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.

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.
