Keep decision making conservative, storm snow is expected to remain reactive to human triggers.

Stick to low angle and supported terrain features free from overhead hazard.

Summary

Confidence

Moderate

Avalanche Summary

Observations are currently limited, however we expect natural activity to have continued through Thursday and Friday in areas with continued snowfall. Rider triggering is still thought to be likely.

Over the last 3 days explosive control has continued to produce widespread storm slab results within the recent storm snow.

Snowpack Summary

Storm totals are expected to vary from 70 cm-1 m by Saturday morning with storm snow sitting over a crust at lower elevations and wind-affected surfaces in the alpine and exposed treeline. Dry snow sluffing from steep terrain features is likely.

The mid and lower snowpack are generally well consolidated. The recent snow has improved travel conditions at lower elevations, but many obstacles, such as sticks and rocks, lurk just below the surface.

Weather Summary

Friday Night

Cloudy with up to 10 cm of snow. 30-50 km/h southerly winds. Freezing level remains steady at 500 m.

Saturday

Cloudy with 10-20 cm of snow. 20-30 km/h southeast ridgetop wind. Treeline temperature -7 °C. Freezing level hovers around 500 m.

Sunday

Cloudy with 5 cm of snow. 10-20 km/h southeast ridgetop wind. Treeline temperature -7 °C. Freezing level hovers around 500 m.

Monday

Heavy snowfall forecast overnight.

Clearing skies on Monday. Light and variable westerly winds. Treeline temperature -7 °C. Freezing level hovers around 500 m.

Terrain and Travel Advice

  • Minimize exposure during periods of heavy loading from new snow and wind.
  • Don't be too cavalier with decision making, storm slabs may remain sensitive to human triggering.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.

Problems

Storm Slabs

An icon showing Storm Slabs

Deeper and more sensitive slabs exist on north and east facing slopes near ridges. Danger may rise quickly if the sun appears.

Good travel habits are key, minimize your exposure to avalanche terrain and evaluate safe spots with caution.
