Banff Yoho Kootenay

Be prepared for the cold when recreating this week. Even a small mishap in the day can become critical in these temperatures. 

An arctic ridge of high pressure will linger in the bulletin region for the remainder of the week. Temperatures will remain frigid, with evening lows down to -30. A temperature inversion has set in at higher elevations. Light winds, sunny skies and temperatures in the low negative teens will make the alpine the place to be.

Wide spread wind effect above treeline has created wind slab on NE to SE aspects. At treeline elevations, up to 65cm of snow sits over the Jan.17 surface hoar. In shallower areas weak facets and depth hoar exist below the Dec 10 interface. In deeper snow packs this basal weakness is less pronounced.

No new avalanches reported or observed today.
