Kootenay Boundary

There is snow on the horizon, but it's hard to say how much. This new snow should bump danger up a notch. Are you a member of Avalanche Canada? Join today at avalanche.ca/membership

Fair - Forecast snowfall amounts are uncertain on Monday

The ridge of high pressure maintains dry conditions on Sunday with a freezing level a little over 1000 m. An approaching Arctic cold front should result in increasing cloud late Sunday and light snow beginning on Monday. Some areas could see 10-15 cm (maybe more) by Tuesday. The freezing level is around 600-800 m and ridge winds are moderate from the N-NW. Tuesday should become drier, sunnier and cooler under the influence of the Arctic High.

No new avalanches have been reported in the past few days.

5-10 cm of new snow sits on the previous snow surfaces. The new snow is being redistributed into thin wind slabs in open lee terrain and is sluffing in steep sheltered terrain. The most prominent feature in the snowpack is the thick upper crust. This crust is supportive all the way to ridge crest and is effectively "capping" the snowpack, keeping riders from tickling any deeper weak layers. On solar aspects the proud crust is on the surface (softening during sunny days), and on shadier aspects there may be 5 - 20 cm of settled storm snow on it. There are still weak layers in the snowpack that we'll continue to monitor, but for now these layers are dormant. We would likely need significant warming and/or heavy loading to re-activate them.
