Regions

Waterton Lakes.

Give the new snow time to settle and be aware that this recent snowfall may be hiding hazards such as stumps and rocks.

Weather Forecast

Thurs: 10-15cm of snow with a 1500m freezing level. Light SW wind

Avalanche Canada's Mountain Weather Forecast is a great regional-scale resource for up-to-date weather information. Here you'll find snow amounts, freezing levels and other aspects of weather important to assessing conditions

SPOTWX is a good resource for local scale weather forecasts.

Snowpack Summary

10-15cm of new snow is expected thursday. This will create storm slabs which sit over old wind slabs on all but north facing slopes in the alpine. Mid snowpack is well consolidated with multiple decomposing crusts found near the base of the snowpack.

Avalanche Summary

No recent reports.

Please consider submitting a MIN report if you see an avalanches.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-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.
