The alpine rating is Loose Wet and Wind Slabs.

Low
Avalanche Summary
Recent explosive control produced small storm slab avalanches on the North shore. Wet loose avalanche activity should peak during the deluge Saturday afternoon and diminish rapidly as surface crust forms.
Snowpack Summary
By Saturday night, heavy rain should have soaked the snowpack at all elevations. A crust will begin to form immediately after, gradually capping the snowpack.
The saturated upper snowpack may still produce wet loose avalanches with a trigger in steep terrain before the crust forms up and free water drains away.
A late-January weak layer (hard crust, facets, or surface hoar) is buried 80 to 120 cm deep, this layer should be entombed beneath a firm crust soon.
The lower snowpack is strong and bonded.
Weather Summary
Saturday night
Cloudy with 10 - 30 mm of mixed precipitation, mostly rain. 40 to 60 km/h southwest ridgetop wind, easing. Freezing level falling to 1500 m.
Sunday
Partly cloudy with wet flurries beginning in late afternoon, minimal accumulations. 15 - 25 km/h southwest ridgetop wind shifting southeast. Freezing level 1500 - 1700 m.
Monday
Clearing in the midday after 10 - 20 cm accumulation overnight and early morning. 20 to 40 km/h south ridgetop wind. Freezing level falling to 1200 m.
Tuesday
Cloudy with wet snowfall bringing 10 - 30 cm of new snow. 40 - 50 km/h southeast ridgetop wind. Freezing level 1200 - 1400 m.

Terrain and Travel Advice
- Loose avalanches may start small, but they can grow and push you into dangerous terrain.
- Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
- Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
Problems
Loose Wet
Triggers in steep terrain may be capable of producing wet snow releases before a surface crust forms and free water drains away. Slopes in direct sunlight are the most concerning.
Aspects: South, South West, West.
Elevations: All elevations.

Wind Slabs
Small wind slabs may form in high alpine parts of the region where dry snow could accumulate.
