There remains a concern for deep weak layers in thin snowpack areas. Warm temperatures and solar radiation have the potential to wake them up.
Weather Forecast
Friday: Sunny. Freezing Level 3000m Light West wind.Saturday: Cloudy with sunny periods. Freezing Level dropping to 1800m. 1-2mm of precipitation possible.Sunday: Cloudy with a chance of flurries. Freezing Level 1600m
Snowpack Summary
Solar affect is the primary concern for Friday. Up to 1m of moist snow on solar aspects during the heat of the day. The lower snowpack remains weak and facetted, and as the warm temperatures continue there is a possibility this layer could produce large avalanches.
Avalanche Summary
A number of Natural, Size 2 loose wet avalanches were observed on Mt. Bertha and along the Akamina Parkway during the week. They entrained a substantial part of the facetted snowpack in some areas, making them larger than one might expect.
