Another day with warmer temperatures up high, caution on solar aspects in the sunshine.The winter permit system comes into effect today, click here Winter Permit Information for further details.
Weather Forecast
We are still under the influence of a high pressure ridge bringing light winds and nil precipitation. Temperatures are still warmer up high and will hover around 0 degrees at 2000m. This pattern is expected to last until Thursday when light snow is expected
Snowpack Summary
Snow pack has settled quite a bit since the storm exposing more early season hazards. There's sun crust on south aspects. November 12 surface hoar layer is down between 50-110cm at higher elevations.
Avalanche Summary
One size 2 natural avalanche in the east of the Rogers Pass summit in highway corridor from Mt Macdonald.
Confidence
Due to the number and quality of field observations
Problems
Persistent Slabs
Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
