Avalanche danger considerable in region, resulting form recent snow storm and warm temperatures.

The Trans-Canada Highway between Revelstoke and Sicamous is currently closed for avalanche control.

DriveBC reports the closure will be from 8 to 10 a.m. Delays of two hours can be expected.

The Canadian Avalanche Centre’s danger rating for the region is Considerable, meaning dangerous avalanche conditions.

“The recent storm snow is the main concern at this time,” says a CAC bulletin. “Southwest winds have transported the snow into windslabs on north through east aspects. The storm slab consists of 40-80 cms across the region. This slab has started to settle, but may be triggered by the forecasted load of new snow. Beneath the slab is a weak layer of facets or small surface hoar that was buried on January 13th. Professionals continue to monitor and test the mid-december surface hoar layer, however it has been quite a while since we have seen any activity on this layer.”

Flurries are expected to end today, with a weak ridge of high pressure moving in. However, moderate gusty westerly winds and flurries are expected to bring another 5-10 cm by evening, states the CAC.
