    Previous southwesterly winds built wind slabs on typical lee slopes. Forecast easterly winds are expected to be light, but may build small wind slabs in unusual areas if they get strong enough.

Confidence

Moderate

  • We are uncertain due to a highly variable snowpack.

Avalanche Summary

Sunday

  • Several small, size 1 wind slabs around 15 cm deep were triggered by skiers in different parts of the region. These slabs generally occurred on steep wind-loaded features.

Friday & Saturday

  • A few loose dry sluffs up to size 2 were observed in different parts of the region.

Snowpack Summary

2 to 10 cm is forecast for overnight and Tuesday, with generally light easterly winds. Older wind slabs formed over the past couple of days may remain triggerable near ridgetops.

Below that, 30 to 60 cm of snow is covering a melt-freeze crust from Feb 7th, with surface hoar over it in isolated sheltered areas. This layer may be reactive in some parts of the region, such as south of Valemount, and near Clearwater where there have been recent reports of whumpfing.

A layer of surface hoar/facets/crust from late January may be found buried 60 to 100 cm. This layer seems to have gone dormant.

The remaining snowpack is well settled with no layers of concern.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • Seek out sheltered terrain where new snow hasn't been affected by wind.
  • Surface hoar distribution is highly variable. Avoid generalizing your observations.
