Regions

Vancouver Island, East Island, North Island, South Island.

Continue to make conservative decisions and give the storm snow time to bond to the crust.

Confidence

Moderate

Avalanche Summary

On Friday one size 1.5 skier remote was reported. This avalanche released on a steep northeast slope at 1400m at the interface between the storm snow and the crust below.

Snowpack Summary

Up to 50cm of new snow has likely been redistributed into wind slabs on north and east aspects and cross loading on others. A new crust likely extends from 1000m up to 1600m. Below 1000m the snow surface could still be moist.

Once again terrain below treeline has limited or no coverage.

Weather Summary

Friday Night

cloudy with up to 5cm of new snow expected. Light southwest winds and freezing levels rising to 1500m.

Saturday

Cloudy with light flurries bringing trace amounts of new snow to higher elevations. Light to moderate westerly winds and freezing level around 1300m.

Sunday

Mostly cloudy with the possibility of light flurries bringing trace amounts of new snow. Light to moderate southeast winds and freezing levels around 900m.

Monday

cloudy with light flurries bringing trace amounts of new snow.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Be alert to conditions that change with aspect and elevation.
  • Closely monitor how the new snow is bonding to the crust.

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.
