Avalanche Summary

Although there were no reports of avalanche activity, we suspect an avalanche cycle occurred on Thursday night / early morning Friday with high freezing levels and heavy precipitations.

Snowpack Summary

Up to 75 mm of precipitation has already fallen since Thursday. This has soaked the snowpack at lower elevations and brought wet and heavy snow at upper elevations only. This wet snow is resting on a crusty surface formed last week below 1400 m. Above 1400 m, it is falling on storm snow from last weekend (30-50 cm), which was bonding well to an underlying melt-freeze crust. The middle and lower snowpacks are strong and well-bonded.

Weather Summary

Wet, warm & windy conditions will continue to impact the region as two more storms will roll into the South Coast ranges over the weekend.

Friday night

Isolated flurries. Local amount 5-10 cm. Strong southwesterly wind gusting 50 km/h. Alpine low -5 °C. Freezing level lowers to 1000 m.


Snow at higher elevations. Local amount 30 cm. Strong southwesterly wind gusting 60 km/h. Alpine low -4 °C. Freezing level around 1200 m.


Rain. Local amount up to 40-50 mm. Strong southwesterly wind gusting 60 km/h. Alpine high -1 °C. Freezing level rises 1800 m.


Cloudy. Isolated flurries. Moderate southwesterly winds gusting 45 km/h. Alpine high -2 °C. Freezing level lowers to 1000 m

Terrain and Travel Advice

  • Be alert to conditions that change with aspect and elevation.
  • The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Avoid areas with overhead hazard.


Loose Wet

An icon showing Loose Wet

Rain and above-freezing temperatures have weakened the snowpack at low elevations, which may remain weak until a solid crust forms. Watch for unstable snow on steep terrain, where loose avalanches are likely to get triggered.

Aspects: All aspects.

Elevations: Treeline, Below Treeline.



Expected Size

1 - 1.5

Storm Slabs

An icon showing Storm Slabs

Moderate to heavy snowfalls are stacking at upper elevations only. The likelihood of natural avalanches will increase as the storm progresses Saturday. Rider-triggerable avalanches will be likely, especially on lees of ridge lines and cross-loaded features.

Aspects: All aspects.

Elevations: Alpine.



Expected Size

1 - 2
