Avalanche Forecast

Moderate

Several small (size 1 to 1.5) dry loose avalanches were triggered in the Lizard Range on Friday.

Wednesday: Near Fernie, two large (size 2) avalanches were triggered with explosives at 2100 m. These failed on buried surface hoar 30 cm deep.

Expecting up to 15 cm of new snow sitting over crusts on solar aspects, surface hoar, wind-affected snow, and facets.

The snowpack contains a couple of thick, hard crusts buried 10 to 20 cm and 30 to 70 cm deep. In most areas, the snowpack has no weak layers below. Except for one location in the Lizard Range, where the crust disappears around treeline and a layer of surface hoar was found. This layer hasn't been found elsewhere in the Lizard Range.

The snow depth at treeline is 50 to 150 cm, with the deepest snowpack near Fernie. Snow depth decreases rapidly at lower elevations.

Friday Night

Mostly cloudy with up to 5 cm of snow, southwest alpine wind 35 to 55 km/h, treeline temperature -9 °C.

Saturday

Mostly cloudy with 5 to 10 cm of snow, southwest alpine wind 15 to 35 km/h, treeline temperature -8 °C.

Sunday

Mostly cloudy with up to 5 cm of snow, alpine wind calm to 15 km/h from various directions, treeline temperature -13 °C.

Monday

Mostly cloudy with a dusting of snow, west alpine wind 35 km/h, treeline temperature -13 °C.

• Storm snow and wind is forming touchy slabs. Use caution in lee areas in the alpine and treeline.
• Storm slab size and sensitivity to triggering will likely increase through the day.
