Summary
Weather Forecast
Friday looks to be a repeat of today's weather, with a mix of sun and cloud and temperatures staying cool (-5 to -15 range). No precipitation is expected, along with light winds. Looks like clear skies and a nice day coming for Saturday.
Snowpack Summary
5-10 cm of loose snow sits on the surface from the last few days in the Bow Summit area, but light winds and a cooling trend has minimized any surface instabilities. The base of the snowpack is weak facets with a 40-60cm stiff snow over top. Triggering is unlikely except in open, shallow snowpack areas and steep south facing slopes in the afternoon
Avalanche Summary
No new avalanches reported today from observations on the Banff/Jasper highway, Stanley Valley, Sunshine Village and Lake Louise areas.
Confidence
Problems
Deep Persistent Slabs
The lower half of the snowpack is weak due to the presence of basal depth hoar and facet layers. Natural and human triggering is unlikely, but possible in steep open slopes with shallow snow, or south and west facing terrain during mid-day.
Aspects: All aspects.
