The freezing level will gradually climb over the next few days. Keep an eye on steep slopes facing the sun if the sun pokes through. Lingering wind slabs at upper elevations are still a concern.
Summary
Confidence
High - The snowpack structure is generally well understood.
Weather Forecast
FRIDAY Night: Cloudy with clear periods, light to moderate northwest and west wind, treeline temperatures -1 C, freezing level 1700 m.
SATURDAY: Mainly cloudy with sunny breaks, moderate southwest wind, treeline temperature 0 C, freezing level 1800 m.
SUNDAY: Cloudy with flurries, accumulation 5-10 cm, moderate to strong southwest wind, treeline temperatures around -1 C, freezing level 1700 m
MONDAY: Mix of sun and cloud, light to moderate northwest wind, treeline temperatures around -5 C, freezing level 1000 m.
Avalanche Summary
On Thursday there were a few reports of human triggered thin storm slab avalanches to size 1.5 on north and south aspects around 2200 m.
Looking forward, wind slabs could still be triggered at higher elevations. Keep your eye out for the sun, as sun-exposed slopes could rapidly deteriorate when the sun pokes through the clouds.
Snowpack Summary
10 to 20 cm of snow accumulated through the week. This overlies a melt-freeze crust on southerly aspects, perhaps small surface hoar crystals on shaded aspects, and otherwise 20 cm of snow from the weekend. This recent snow has generally been stabilizing, but there could be some wind slabs that linger at higher elevations. All of this recent snow sits above a widespread crust, with the exception of high north-facing terrain.Â
Terrain and Travel
- Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
- Be alert to conditions that change with elevation and sun exposure.
Problems
Wind Slabs
Recent snow may still be reactive to riders, particularly on steep wind affected slopes. Carefully assess for wind slabs prior to committing to steep features with high consequence.
Aspects: North, North East, East, South East, North West.
