Lizard-Flathead

Small wind slabs may linger on northerly aspects in isolated locations below alpine ridgetops.

On Monday, a few naturally triggered storm slabs and wet loose avalanches up to size 1.5 were reported in the alpine near Fernie.

NOTE: Observations are currently very limited in this region.

Up to 30 cm of recent snow in localized areas and strong variable wind may have formed wind slabs on lee slopes at upper elevations. However, triggering these slabs will become unlikely on sunny slopes that have a sun crust.

This snow overlies a robust crust everywhere except northerly aspects at upper elevations, where previous snow surfaces may have remained dry.

The mid/lower snowpack is well settled and strong.

Lower elevations are melting out rapidly.

Tuesday Night

Clear skies. 5 to 10 km/h west ridgetop wind. Treeline temperature -4 °C. Freezing level valley bottom.

Wednesday

Sunny. 5 to 10 km/h northwest ridgetop wind. Treeline temperature 3 °C. Freezing level 2400 m.

Thursday

Sunny. 20 to 30 km/h east ridgetop wind. Treeline temperature 5 °C. Freezing level 2600 m.

Friday

Mix of sun and cloud. 20 to 30 km/h east ridgetop wind. Treeline temperature 4 °C. Freezing level 2500 m.

• Carefully evaluate steep lines for wind slabs.
• Avoid sun-exposed slopes, especially if the snow surface is moist or wet.
• Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
