Avalanche Forecast

Moderate - Uncertainty is due to the timing, track, & intensity of the incoming weather system.

MONDAY NIGHT: 10-20 cm of snow above 1000 m, 50-80 km/h wind from the southwest, alpine temperatures around -5 C.

TUESDAY: Light precipitation throughout the day with another 10 cm of snow above 1200 m, 50-70 km/h wind from the southwest, alpine high temperatures around -2 C.

WEDNESDAY: 20-40 cm of new snow above 1000 m, 50 km/h wind from the southwest in the morning then decreasing in the afternoon, alpine high temperatures around -2 C.

THURSDAY: Mix of sun and cloud, 30 km/h wind from the southwest, alpine high temperatures around -4 C.

Minimal avalanche activity has been reported over the past week as the snowpack is generally thin and the weather has been benign. That is about to change as significant amounts of new snow and wind are expected to form fresh slabs this week. The greatest concern will be in wind affected terrain and where the snow falls onto smooth surfaces (such as areas where there is enough snow to cover rocks and trees).

A stormy week will bring much needed snow to the Sea to Sky region. 20-40 cm of new snow is possible by Tuesday afternoon with much more expected on Tuesday night. The new snow will cover firm wind pressed snow and hard crusts. Typical snowpack depths in the alpine currently range between 50 and 150 cm, depending on the amount of wind affect. Snowpack depths taper quickly with elevation with little to no snow below 1800 m.
