Lizard-Flathead, Akamina, Flathead, Lizard.

Continue to make conservative terrain choices as the storm settles and pay attention to conditions that change with elevation.

Storm slab reactivity could increase if the sun comes out.

Confidence

Moderate

Avalanche Summary

Over the past few days numerous natural and explosive triggered storm slabs up to size 2 have been reported. These avalanches have generally been on north and east aspects at treeline and above. A couple natural cornice falls have also been noted with additional reports of wind transport continuing to build cornices.

Snowpack Summary

30 to 50 cm of recent storm snow sits on wind affected surfaces at all elevations. Deeper deposits exist in north and east facing terrain features due to west and southwest winds.

Check out this great MIN that discusses conditions near Fernie.

The mid-snowpack is generally well settled. The lower snowpack includes a layer of weak sugary crystals near the ground. These facets are slowly gaining strength and have not produced recent avalanche activity. We continue to track the layer and watch for any signs that it could wake up and produce very large avalanches.

Weather Summary

Saturday Night

Mostly clear with the possibility of light flurries bringing trace amounts of new snow. Moderate southeast winds and a low of -12°C at 1800 m.

Sunday

A mix of sun and cloud with the possibility of light flurries bringing a few centimeters of new snow. Moderate southeast winds easing throughout the day and a high of -8°C at 1800 m.

Monday

A mix of sun and cloud with no new snow expected. Light southerly winds and a high of -7°C at 1800 m.

Tuesday

A mix of sun and cloud with no new snow expected. Light southwest winds and a high of -5°C at 1800 m.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Avoid freshly wind loaded features, especially near ridge crests, roll-overs and in steep terrain.
  • Avoid avalanche terrain during periods of strong sun.
  • Minimize your exposure time below cornices.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
