Weather Forecast
The next few nights will be cold and -3 to -6 during the day with scattered clouds, mainly sunny, and light west winds. No new snow is expected until Saturday.
Snowpack Summary
Approximately 20cms of soft surface snow in sheltered locations at TL over a supportive mid-pack. This is sitting on a weak basil facet layer. BTL, the HS is more inconsistent in depth and support. Solar aspects have a thin sun crust down 20cms and producing moderate to hard resistant compression test results. Recent sun may create surface crusts.
Avalanche Summary
No field trip Wednesday. Tuesday observed two new avalanches observed above the Maligne road which appeared to be solar triggered. Some cornice failures also noted in Icefields area which triggered the basal weakness.
Confidence
Timing or intensity of solar radiation is uncertain
