Avalanche Forecast
Regions: Kootenay Boundary.
Confidence
Poor - Due to the number of field observations
Weather Forecast
Sunday: A relatively cool unstable air mass will continue to bring showers or flurries to the region with light to locally moderate accumulations. Winds should remain light to moderate from the southwest with freezing levels hovering around 1600m.Monday: Scattered flurries are expected throughout the day, although some clearing is expected by late afternoon as a dry ridge of high pressure starts to develop. Winds are expected to be light from the northwest with freezing levels at about 1700m.
Avalanche Summary
Expect loose wet avalanches in steep terrain if it is raining or during sunny periods, especially if the sun or rain is affecting fresh snow. Spring squalls may bring locally heavy precipitation and new storm or wind slabs may develop in higher terrain if you see significant new snow accumulation. Cornices collapses have been reported during periods of daytime warming. Occasionally these heavy triggers have caused large deep slab avalanches on the slopes below.
Snowpack Summary
This is a broad general summary of conditions in the region based solely on recent weather data and previous snowpack information. It should be supplemented with local observations to help assess avalanche danger.Over the last few days we have seen moderate to locally heavy amounts of new snow mixed with showers or periods of rain below 1600-1800 m. Southwesterly winds have likely formed pockets of wind slab at higher elevations in lee of ridges and terrain features. The late January/early February persistent weak layer is deeply buried but could still wake up during periods of heavy precipitation (especially rain) or significant warming and solar radiation. Be particularly wary of this on large open alpine slopes. Cornices are large in some areas and should be given a wide berth.
