6:20 AM Update:
Avoid avalanche terrain and overhead hazard - New snow and wind are creating dangerous avalanche conditions.
Up to 45 cm of new snow may be forming reactive new slabs at all elevations, but will be particularily prone to triggering on wind-loaded soples near ridgetops.
Saturday
One size 1.5 naturally triggered wind slab, and some dry loose sluffing were observed.
Friday
Reports of natural and skier-triggered size 1 wind slabs primarily in alpine cross-loaded terrain. Additionally, some cornices failed without triggering slabs on the slopes below.
Thursday
Natural, human and remote-triggered size 1 to 1.5 wind slabs were reported, running on recently faceted surface snow in the Hurley.
Around 10 to 30 cm of new snow is expected in the region by Monday afternoon. This will add to the 5 to 10 cm that fell on Sunday.
Forecast strong southerly ridgetop winds are expected to build thicker and more reactive slabs on lee slopes.
In some sheltered features, a layer of surface hoar may be found buried 5 to 10 cm below the new snow.
20 to 50 cm is currently sitting over the early February crust that is thin and breakable on northerly aspects to 2300 m and thick on southerly aspects.
A widespread crust and facet layer from late January is buried around 30 to 80 cm deep.
The mid and lower snowpack is generally well settled and strong.
Sunday Night
Mostly cloudy. 5 to 15 cm of snow. 40 km/h south ridgetop wind. Treeline temperature -6 °C.
Monday
Mostly cloudy. 2 to 10 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -7 °C.
Tuesday
Mostly sunny. 20 km/h west ridgetop wind. Treeline temperature -8 °C.
Wednesday
Mix of sun and clouds. 0 to 3 cm of snow. 60 km/h west ridgetop wind. Treeline temperature -7 °C.
