Update 6:10am: New snow and wind loading have formed reactive storm slabs, especially on north through east facing slopes.
Stick to conservative terrain sheltered from the wind.
Up to 40 cm of new snow may be forming reactive new slabs at all elevations, but will be particularly be prone to triggering on wind-loaded slopes near ridgetops.
We are aware of an avalanche incident near Pemberton on Tuesday. Further details are not yet available, but will be provided when possible.
On Monday, the region saw numerous natural (size 1 to 2) storm slab avalanches and a smaller human-triggered (size 1) avalanche. Dry loose sluffing was reported from steep terrain features.
Strong westerly winds will be driving the avalanche danger on Wednesday. Natural avalanches are possible, and human-triggered likely.
Up to 40 cm of new snow has blanketed the region. Strong southerly ridgetop winds have likely formed thicker and more reactive slabs on leeward slopes. The new snow sits over a variety of old snow surfaces, including surface hoar, crusts, and facets. Expect the potential for a poor bond at the storm snow interface.
Up to 100 cm is sitting over the early February crust. That crust is thin and breakable on northerly aspects to 2300 m, but thick on southerly aspects.
A widespread crust and facet layer from late January is buried around 100+ cm deep.
