Expect dangerous avalanche conditions through the weekend.

The new Forecaster Blog outlines how to manage changing conditions.

We have received a few reports of storm slabs sliding on buried surface hoar.

We expect the frequency and size of avalanches to increase through the weekend.

The new snow has fallen on a variety of old surfaces. There is surface hoar, more prevalent around treeline and below, a crust on sun-facing slopes, and 20 to 30 cm of low-density faceted snow in sheltered areas.

Dry January conditions have created a weak, faceted upper snowpack with multiple surface hoar and crust layers. These layers are a concern with the new snow amounts forecasted.

The mid and lower snowpack remains generally well-settled and strong.

Friday night

Cloudy with 10 to 20 cm of snow. 30 to 50 km/h southwest ridgetop wind. Treeline temperature -7 °C.

Saturday

Mostly cloudy with 5 to 10 cm of snow. 10 to 30 km/h southwest ridgetop wind. Treeline temperature -15 °C.

Sunday

Mostly cloudy with 0 to 5 cm of snow. 10 km/h east ridgetop winds. Treeline temperature - 15 °C.

Monday

Mostly cloudy with 0 to 2 cm of snow. 10 km/h east ridgetop winds. Treeline temperature -17 °C.

• Storm slab size and sensitivity to triggering will likely increase through the day.
• Storm slabs in motion may step down to deeper layers resulting in large avalanches.
• Avoid avalanche terrain during periods of heavy snowfall.
