Avalanche Forecast

Fair - Freezing levels are uncertain

Light snow (5-10 cm) overnight combined with moderate Southeast winds and freezing levels around 1000 metres elevation. Flurries with periods of light snow during the day on Friday combined with moderate to strong Southwest winds. Freezing levels expected to rise up to about 1400 metres on Friday. Light snow (3-8 cm) by Saturday morning and continued snowfall (10-15 cm) during the day Saturday as freezing levels continue to rise and Southwest winds increase to strong-very strong. Freezing levels are forecast to spike up to about 2000 metres by Sunday morning combined with 10-20 mm of precipitation and very strong Southwest winds. This may be rain up into the alpine.

No new reports of avalanches. Expect new storm slab avalanches to increase as the new storm develops.

The new storm is expected to develop a storm slab above the mix of old surface forms that include hard crusts, near surface facets, and surface hoar. Conditions in the Coquihalla area are quite different to the Duffey/Hurley regions. Reports from the Coquihalla suggest there's less than 1 m of snow in most avalanche areas. On the surface, fairly widespread surface hoar development has been reported. Below this, a small amount of recent storm snow overlies a thick rain crust. In the north, we have very limited observations. That said, I expect a deeper, more complex snowpack where well settled storm snow overlies a mix of crusts and facets which formed in November.
