Avalanche Forecast

Moderate

Wednesday: Explosive control east of Penticton produced several avalanches sized 1 to 2. Some were small wind slabs but the larger avalanches failed on a persistent weak layer of facets over a crust up to 60 cm deep.

Tuesday & Monday: Explosive control in different parts of the region produced several small to large (up to size 2) avalanches in east and southeast facing alpine and treeline terrain. They all failed on a layer of facets or crust buried by the recent storm.

A surface crust or moist snow may be found at lower elevations and on sun-affected slopes. Otherwise, 30 to 60 cm of accumulated settling storm snow sits over a crust in many areas or surface hoar / facets in some wind-sheltered areas. The highest storm snow amounts fell in southern parts of the region, and the lowest in the north. A weak layer buried in late January consisting of surface hoar and facets or a crust, is buried 50 to 90 cm and remains a lingering concern. Below this, the mid and lower snowpack is generally settled and strong.

• Start with simple terrain and gather information before committing to bigger features.
• The more the snowpack warms up and weakens, the more conservative your terrain selection should be.
• Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
• Be alert to conditions that change with elevation and sun exposure.
