Confidence
High - The snowpack structure is generally well understood.
Weather Forecast
Saturday night: Cloudy periods with isolated flurries bringing a trace of new snow. Light northwest wind. Freezing level 500 m.
Sunday: Broken cloud with isolated flurries bringing up to 5-10 cm new snow. Light to moderate southwest wind. Freezing level 400 m.
Monday: Mix of sun and cloud. Light northwest wind. Freezing level 300 m.
Tuesday: Flurries bringing 5-10 cm new snow. Moderate west wind. Freezing level 300 m.
Avalanche Summary
A widespread loose wet avalanche cycle is expected to have run during the storm Friday but we have received no reports.
Snowpack Summary
Storm slabs may exist in the high alpine and where snow accumulated toward the tail end of the storm. They will likely be well settled, wind pressed and well adhered to old surfaces.Â
At lower elevations, the snowpack is refreezing in the cool temperatures. A dusting of new snow may sit on top of the crust. Snowpack depths range from almost nothing below 1000 m to 150-250 cm deep around the peaks of the north shore mountains (1400 m).
Terrain and Travel
- When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
- A crust on the surface will help bind the snow together, but may make for tough travel conditions.
- Closely monitor how the new snow is bonding to the crust.
Avalanche Problems
Storm Slabs
Storm slabs may exist in the high alpine and where snow accumulated after freezing levels peaked and began to drop toward the tail end of the storm. This snow will have fallen on a moist surface and is likely bonding well.
