The alpine rating is Wind Slabs.
, the treeline rating is , and the below treeline rating is Known problems includeWe have limited observations from the this area. From other observations along and E of the divide, watch for isolated wind slabs which may be sitting over a rain crust depending on elevation and aspect. This is likely the same in Little Yoho. SH
Summary
Weather Forecast
Light winds ranging from S-SE Friday with more seasonal temperatures staying well below freezing compared to the warm temperatures we have had this past week. Only flurries for Friday and light snow amounts through the weekend.
Snowpack Summary
20-30cm of new snow at treeline from a storm at the start of the week was accompanied by moderate to strong SW to NW winds which formed some wind slabs at higher elevations. This new snow sits on the Nov. 12 crust (1-2cm thick ) which is present on all but high N aspects (not seen above 2400m on N. aspects) . Below this is a well settled snowpack.
Avalanche Summary
Sluffing in steep terrain and some small wind slabs over the Nov. crust noted. We have limited observations from high alpine areas in Little Yoho.
Confidence
Problems
Wind Slabs
New wind slabs have formed with the new snow. So far things seem to be bonding reasonably well to the buried Nov 12 crust however some skier triggering has been reported on this layer.
- Be careful with wind loaded pockets while approaching and climbing ice routes.
- Use caution in lee areas. Recent wind loading have created wind slabs.
Aspects: North, North East, East.
