Hazard has dropped to Low but it is still worth evaluating all terrain with caution. Ski conditions are rugged at the moment at treeline and below but ice climbing is getting better with each passing day as cooler temperatures prevail.
Summary
Weather Forecast
Westerly flow and mild temps for today and tonight and then for Saturday Northwesterly flow creating a cooling trend. Sunday the flow goes back to westerly and light snowfall develops through until the beginning of the week. Freezing levels should go to valley bottom by tomorrow and remain low for the next few days.
Snowpack Summary
After a period of warm weather, the return to colder temperatures has improved the stability of the snowpack, particularly at treeline and below where strong melt-freeze crusts now dominate. In isolated areas we expect the Dec 18 surface hoar layer to remain, but triggering is unlikely. Recent winds have blasted the terrain at higher elevations.
Avalanche Summary
No new natural avalanche activity was observed or reported today, however one explosive result up to size 2 out of a steep & complex alpine feature was reported by Lake Louise yesterday so avalanches are still possible out of steep, rocky alpine terrain in isolated terrain features with larger triggers.
Confidence
Problems
Persistent Slabs
While ski conditions are rough right now, avalanche conditions have improved. Although it seems unlikely, there is still some uncertainty about the Dec 18 surface hoar layer down about 50 cm from the surface.
Aspects: All aspects.
Elevations: Alpine, Treeline.
