Regions

Little Yoho.

Low density snow has refreshed the ski quality. Conditions are getting better, however, normal precautions apply.

Weather Forecast

Light flurries, light wind and seasonal temperatures are expected for the next few days. Because of this, expect little change to the danger rating.

Snowpack Summary

Convective flurries deposited up to 20cm of low density storm snow in the lake Louise area last night. In the alpine, this new snow overlies hard wind slabs, created from the strong to extreme wind events over the last week. Other areas to watch are

Avalanche Summary

Some small point release avalanches in the Lake Louise back country today. Not bigger than size 1. Otherwise nothing reported or observed.

Confidence

Timing, track, or intensity of incoming weather system is uncertain

Problems

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.
