Avalanche Forecast

On Sunday, a naturally triggered size 2.5 deep persistent slab avalanche was reported on a steep southeast aspect at 1800 m in the Northern Selkirks. The crown depth was reported as 200 cm.

Numerous naturally triggered wet loose avalanches up to size 2 were reported on sunny aspects in the alpine.

NOTE: Observations are currently very limited in this region.

Up to 15 cm of recent snow may be found at upper elevations. This snow overlies a robust crust everywhere except northerly aspects at upper elevations.

Most terrain has undergone strong melt-freeze cycles, but the snowpack remains slightly more complex on north-facing alpine slopes. In the Selkirks, two surface hoar layers are buried 30 to 60 cm deep, and older weak layers may exist in the middle of the snowpack across the region.

However, none of these layers are expected to be reactive under current conditions.

Monday Night

Clear skies. 10 to 20 km/h northwest ridgetop wind. Treeline temperature -6 °C. Freezing level valley bottom.

Tuesday

Sunny. 5 to 10 km/h northwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1900 m.

Wednesday

Sunny. 10 to 20 km/h northwest ridgetop wind. Treeline temperature 3 °C. Freezing level 2300 m.

Thursday

Sunny. 10 to 20 km/h southeast ridgetop wind. Treeline temperature 5 °C. Freezing level 2600 m.

• Pay attention to cornices and give them a wide berth when traveling on or below ridges.
• Carefully evaluate steep lines for wind slabs.
• Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
