    Expect loose, wet avalanches on all solar aspects starting in the early afternoon. There has been a lot of new snow lately, and Sunday will be the first bout of sun we will have seen in a while.

Weather Forecast

A clearing trend overnight into Sunday should provide a decent freeze. We will return to a more regular spring freeze/thaw pattern for the next couple of days, with strong diurnal swings. Alpine temperatures should stay below zero on Sunday with light Northerly winds.

Snowpack Summary

A very weak freeze overnight was barely holding the snow together today at treeline and below treeline Saturday, with isothermal snow one forecaster likened to clam chowder underneath. Solar aspects in the alpine were becoming moist today, with mainly dry powder on northerly aspects.

Avalanche Summary

Numerous loose wet slides on steep solar aspects in the alpine to sz. 1.5 today in the Sunshine Village area.

Confidence

Freezing levels are uncertain on Wednesday
