Avalanche Forecast

Fair - Timing, track, or intensity of incoming weather system is uncertain on Friday

Overnight and Friday: Freezing level dropping down to about 600 metres overnight. Snow starting in the early morning near the coast and moving inland as a warm front moves across the region. Expect 15-20 cm of snow near the coast, and 10-15 cm inland during the day. Southwest winds should build to strong values by the afternoon and freezing levels should rise to about 1500 metres.Saturday: A trailing cold front should bring another 15-20 cm of snow to near coastal areas and 5-10 cm further inland by morning. Winds should slow to moderate Southwest during the day as snow continues. Freezing level rising to about 1500 metres during the day.Sunday: Snow ending overnight or early morning. Light Southerly winds and freezing levels rising to about 1300 metres.

No new reports of avalanches.

There may be some areas where the recent snow does not bond well to melt-freeze crusts on solar aspects. The forecast new storm should add a new load above these weak bonds and may be sensitive to triggering from light additional loads like skiers or riders. The persistent weak layers from early March and early February continue to be a concern. The March weak layer of wind-scoured crusts, melt-freeze crusts, and/or surface hoar is reported to be down 70-80 cm. The February crust/facet/surface hoar layer is now deeply buried down 150-250 cm and may still be triggered by heavy loads like cornice falls or storm slab avalanches in motion. Long fracture propagations resulting in very large avalanches are possible with this layer. Avalanches releasing on these layers may step down to the ground during periods of strong solar radiation or warm spring rain.
