Avalanche Forecast

Many storm slabs were triggered naturally and by riders on Sunday, releasing within the weekend's storm snow. We expect to see more evidence of a natural cycle from the weekend as the skies clear.

Looking forward, storm slabs could still be triggered by riders in wind-sheltered terrain and wind slabs likely dominate in wind-exposed terrain at higher elevations.

Around 50 cm of snow accumulated over the weekend with strong southwest wind. Storm slabs are found in wind-sheltered terrain mostly at treeline elevations and below whereas wind slabs are prevalent in lee terrain features at treeline and alpine elevations. Storm slabs may overly a hard melt-freeze crust up to treeline elevation on sun-exposed slopes and below 1000 m on shaded aspects. The storm likely grew cornices, which could weaken if sunny skies prevail.

A layer of faceted grains and melt-freeze crust may be found about 100 to 200 cm deep. This layer hasn't produced avalanches in over a week and is currently dormant.

Monday Night

Mostly clear skies with no precipitation, 20 to 30 km/h northwest wind, treeline temperature -11 °C.

Tuesday

A mix of sun and cloud with no precipitation, 20 km/h northwest wind, treeline temperature -9 °C.

Cloudy with snowfall, accumulation 10 to 15 cm, 70 km/h southwest wind, treeline temperature -5 °C.

Cloudy with snowfall, accumulation 15 to 25 cm, 20 km/h southwest wind, treeline temperature -6 °C.

• Continue to make conservative terrain choices while the storm snow settles and stabilizes.
• Use increased caution at all elevations. Storm snow is forming touchy slabs.
• Carefully evaluate steep lines for wind slabs.
• Watch for signs of instability like whumpfing, hollow sounds, shooting cracks or recent avalanches.
• Minimize your exposure time below cornices.
