Regions

Banff Yoho Kootenay.

A forecasted warming trend Sunday will deteriorate snowpack at lower elevations. Even short period of solar inputs may cause higher than expected reactivity of the loose wet problem.

Weather Forecast

Minimal re-freeze Saturday night at valley bottom. Freezing levels Sunday are expected to reach 2200m with valley bottom high temps near +8. Light precipe with minimal accumulation and moderate to strong winds are forecasted Sunday. The possibility of solar inputs could deteriorate the snowpack structure at lower elevations quickly.

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

No new avalanche observations Saturday. Forecast team observed more evidence of last Wednesdays avalanche cycle.

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.
