Kootenay Boundary.
You'll likely find a dusting of snow above a thick and hard melt-freeze crust. Apply good backcountry travel habits for a safe day.
SUNDAY NIGHT: Cloudy with snowfall, accumulation 2 to 5 cm, 20 to 30 km/h southwest wind, alpine temperature -2 C, freezing level 1500 m.
MONDAY: Cloudy with intermittent snowfall, 10 km/h south wind, alpine temperature -3 C, freezing level 1600 m.
TUESDAY: Partly cloudy, 10 km/h southwest wind, alpine temperature -1 C, freezing level 2000 m.
WEDNESDAY: Partly cloudy, 10 km/h south wind, alpine temperature -1 C, freezing level 2000 m.
A few small wet loose avalanches were observed out of steep sun-exposed terrain on Sunday. Avalanche activity is expected to diminish on Monday under cooler and cloudy conditions.
A dusting of snow on Sunday night will overly a thick melt-freeze crust from recent warm air to the mountain tops. A dry snowpack may still be found at high elevations on north aspects. Cornices are large and always have the potential of failing.
Deeper in the snowpack, a persistent weak layer from late January is buried around 80 to 150 cm and is composed of a combination of surface hoar, facets, and crusts. We haven't received a report of avalanche activity on this layer since late February. The likelihood of triggering it on Monday is low, with a thick melt-freeze crust on the snow surface.
As always, best to avoid shallow, rocky areas where a weak and faceted snowpack may be found.
