There is high variability with the amount of precipitation and whether it'll fall as rain or snow.
Rain on snow will rapidly raise the danger.
No new avalanches were reported by 4:30 pm on Saturday.
A few small (size 1) storm slab avalanches were triggered on Friday by riders and with explosives.
On Thursday there were a few small (size 1-1.5) storm slab avalanches west of Winlaw. North aspect, treeline, 35 cm deep.
Numerous natural and human-triggered large (size 2) avalanches were reported on Tuesday and Wednesday. Some were remotely triggered from far away..
The snowpack has two buried weak layers of concern:
A layer of facets and surface hoar buried 30 to 60 cm deep, covered by a thin crust at lower elevations but remaining active higher up.
A crust and facet combo from the new year down 80 to 100 cm. This layer seems to be becoming active now that it has a significant load over it from the continued trickle of snow.
Currently, the mid and lower snowpack is generally well-bonded, featuring a thick crust near its base.
Cloudy with 5 to 10 cm of snow, south alpine wind 10 to 30 km/h, treeline temperature 0 °C, freezing level 2500 m.
Cloudy with 5 to 10 cm of snow or rain, southwest alpine wind 30 km/h, treeline temperature 2 °C, freezing level 2500 m.
Mostly cloudy with a trace of snow or rain, south alpine wind 25 to 35 km/h, treeline temperature 5 °C, freezing level 3000 m.
Mostly cloudy with 5 cm of snow, south alpine wind 35 to 45 km/h, treeline temperature 3 °C, freezing level 2000 m.

Terrain and Travel Advice
- The first few hours of rain will likely be the most dangerous period.
- Make conservative terrain choices and avoid overhead hazard.
- Avoid steep convex slopes.
Expect storm slabs to be the deepest and most reactive where the snow has been affected by the wind.
