Seek out sheltered simple terrain for the best riding conditions. Storm snow on steep slopes and wind affected features may remain reactive to human triggers.

Terrain and Travel Advice:
  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Don't be too cavalier with decision making, storm slabs may remain sensitive to human triggering.
  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
Storm Slab

Storm snow is covering a variety of surfaces including stiff wind slabs and a faceting crust, which may take time to bond.

Strong southwesterly winds are transporting storm snow into deep pockets in lees. Be especially cautious as you transition into wind-affected terrain. Watch for an increase in slab properties in wind-blown areas.

At lower elevations precipitation may fall as wet snow or rain, watch for loose wet avalanche potential on steep slopes as the surface snow loses cohesion.

Avalanche Summary

On Friday, natural storm slabs were reported to size 1.5.

On Thursday, several small wind slab avalanches were skier accidentally triggered, skier remotely triggered and naturally triggered up to size 1. All avalanches were reported on north and east aspects at 2000 m.

If you head to the backcountry please post your reports and photos to the Mountain Information Network, the information is very helpful to forecasters.

Snowpack Summary

Expect up to 30 cm of storm snow at higher elevations by Sunday morning. At lower elevations this may have fallen as mixed precipitation or rain. Storm snow overlies old wind affected surfaces and hard crusts. Strong southwest winds are transporting storm snow and building deep pockets in on north and east facing terrain.

A crust from mid-January can be found down 40 to 70 cm deep. A number of weak layers exist within the middle and lower snowpack, but the thick crusts sitting above them make triggering avalanches on these layers unlikely. The areas of concern in terms of triggering a deeper layer are shallow rocky areas.

Weather Summary

Saturday Night

Cloudy skies overnight with 5-10 cm of snow expected overnight. Freezing levels sit around 1200 m, with moderate southerly winds.

Sunday

Cloudy skies, 5 cm of snow expected. Freezing levels sit around 1000-1500 m, with southerly winds easing to light westerlies.

Monday

Mostly cloudy skies with up to 15 cm of snow. Strong west/southwest winds. Freezing levels around 1500 m.

Tuesday

Cloudy. Moderate to heavy snowfall with strong southwest winds. Freezing levels around 1000 m.

Tuesday

Cloudy with isolated flurries, 10-15 cm accumulation. Southwesterly ridgetop winds 40 to 60 km/h. Treeline temperatures warm to -1 ˚C. Freezing levels 1300 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice:
  • Seek out wind sheltered terrain below treeline where you can avoid wind slabs and find great riding.
  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Don't be too cavalier with decision making, storm slabs may remain sensitive to human triggering.
Storm Slab

Storm snow sits above a hard melt freeze crust, which may take time to bond. Back off steep slopes until they've had time to stabilize. Be especially cautious where winds have redistributed snow into deep pockets in lees, watch for an increase in slab properties and reactivity.

At lower elevations precipitation may fall as wet snow or rain, watch for loose wet avalanche potential on steep slopes as the surface snow loses cohesion.

Avalanche Summary

No significant avalanches have been reported in the last few days however backcountry users should expect to see evidence of a natural avalanche cycle within the storm this weekend.

Please continue to post your reports and photos to the Mountain Information Network, the information is very helpful to forecasters.

Snowpack Summary

Expect up to 40 cm of storm snow at higher elevations by Sunday morning. At lower elevations this may have fallen as mixed precipitation or rain. Storm snow sits on a widespread melt-freeze crust. The crust varies in thickness from thick and supportive to thin and breakable. The middle and lower snowpack is strong and bonded.

Weather Summary

Saturday Night

Cloudy skies overnight with light accumulations expected, 5-10 cm. Freezing levels sit around 1000 m, with moderate southerly winds.

Sunday

Cloudy skies with flurries, up to 5cm of snow expected. Freezing levels sit around 1000-1500 m, with southerly winds easing to light northwesterlies.

Monday

Mostly cloudy skies. Moderate snowfall returns, up to 25 cm. Strong west/southwest winds. Freezing levels around 1500 m.

Tuesday

Cloudy. Heavy snowfall delivers over 50 cm, with strong southwest winds. Freezing levels around 1000 m.

More details can be found in the Mountain Weather Forecast.

Confidence: moderate
Uncertainty is due to how quickly the snowpack will recover and gain strength.

Steer clear of freshly wind loaded features. New snow and strong winds have loaded north and east facing terrain.

Head to sheltered and supported terrain features for the best chance of finding good riding conditions.

Terrain and Travel Advice:
  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Be carefull around freshly wind loaded features.
  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
Wind Slab

Strong southwesterly winds are forming new wind slabs on lee slopes in the alpine and at treeline. Watch for typical wind loading around ridgelines and be aware of mid slope cross loaded features.

Deeper weak layers have not produced avalanches for sometime, but may be possible to trigger with step down avalanches.

Avalanche Summary

Wind slabs were reported throughout the region this week, with a notable remotely triggered size 1.5 failing on surface facets at treeline elevation.

Loose dry activity was reported out of steep rocky slopes on Friday.

Please continue to share any observations or photos on the Mountain Information Network.

Snowpack Summary

Strong southwest winds continue redistributing snow into fresh wind slabs in alpine and treeline terrain. In the alpine wind slabs cover scoured northerly aspects. In sheltered areas, 10 to 20 cm of soft snow can be found. A surface crust can be found below 1800 m and at all elevations on steep solar aspects.

In the mid snowpack, a weak layer can be found 50 to 100 cm deep, as a decomposing crust, or in many places, it's more of a soft and weak section of the snowpack. There is a widespread weak layer of facets and depth hoar at the bottom of the snowpack, most concerning in the Hurley/Birkenhead areas. This layer is still a concern for step down avalanches or very large triggers (eg. cornice fall). It is most problematic in steep and rocky start zones where the snowpack varies rapidly from thick to thin.

Generally, the snowpack in this region is weak and shallow. Snowpack depths around treeline are highly variable and range between 150 to 250 cm.

Weather Summary

Saturday Night

Cloudy skies overnight with isolated flurries possible. Trace accumulations. Freezing levels sit around 1200 m, with moderate southerly winds.

Sunday

Cloudy skies with isolated flurries possible. Trace accumulations. Freezing levels sit around 1000-1500 m. Light to moderate southwest winds.

Monday

Mostly cloudy skies with up to 5 cm of snow. Strong southwest winds. Freezing levels around 1500 m.

Tuesday

Cloudy. 5-10 cm, freezing levels around 1500 m. Strong southwest winds.

Monday

1500 m.

Confidence: moderate
Uncertainty is due to the complexity of the snowpack’s structure.
Uncertainty is due to the extreme variability of wind effect on the snowpack.
