Avalanche Forecast

Fair - Timing or intensity of solar radiation is uncertain on Sunday

Light snow fall is expected on Sunday, petering to flurries on Monday. On Tuesday, a ridge moves in, starting a few days of fine, sunny weather.  The freezing level is around 1500 m by day, falling towards valley floor by night. Winds are generally light.

A handful of recent large avalanches have been reported over the last few days. Many of these have been on north aspects, with the odd event on other aspects. There has also been a number of cornice falls.

Recent squally snow showers have brought 10-25 cm of snow, which has been shifted into wind slabs. This new snow sits above a crust which varies in thickness with elevation. Cornices are large and should be given a respectful berth. Sun is likely to destabilize new snow and cornices.Two crust/facet interfaces, formed in March and February, sit about 80-120 cm deep in the snowpack. These weaknesses are becoming more stubborn to trigger, but still react in snowpack tests and have potential for wide propagations and very large avalanches if triggered. Most likely trigger spots would be thin snowpack areas, or triggering with a large load like a cornice fall.Basal facets are on operators' list of concerns. Deep snowpack issues sometimes wake up in the spring, so should not be forgotten.
