Regions

Banff Yoho Kootenay.

Avalanche danger will be directly related to solar input and freezing levels. Many areas will have a LOW danger rating unless heating takes place or there is a lack of overnight freeze. Monitor locally for this.

Weather Forecast

Valley bottom freezing levels Saturday AM rising to 2000m with light winds. We may see a few cm along the divide, and possibly a bit of rain at lower elevations. Forecasts are calling for more cloud cover along and West of the divide, and less to the East.

Snowpack Summary

Surface melt freeze crusts extend high into the alpine on solar aspects. On shady aspects, 10cm of snow from Thursday AM is well settled. Several persistent layers are buried in the snowpack, consisting of crusts and/or facets. These are currently unreactive but may wake up in the future as spring heat starts to penetrate deeper in the snowpack.

Avalanche Summary

One loose wet size 2 was reported above Bourgeau left on a S aspect. No other avalanches reported or observed.

Confidence

Freezing levels are uncertain on Saturday

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.
