Regions: East Island, North Island, South Island, Vancouver Island, West Island.

New snow may have a hard time bonding to existing crusts and hard surfaces. Approach wind loaded terrain with caution and monitor snowfall amounts in your area as they will vary across the region.

Moderate

Avalanche Summary

No new avalanche activity has been reported.

If you are out in the backcountry please consider filling out a Mountain Information Network report.

Snowpack Summary

5-10cm new snow sits on a melt-freeze crust on most aspects and elevations. Our field team is reporting that this small amount of new snow is not bonding well to crusty surfaces. More snow is forecast later in the week and this poor bond will be a problem.

The crust ranges from roughly 1 to 10 cm. Below this crust, the snowpack is moist and generally well settled and bonding, with no current layers of concern.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Pay attention to the wind, once it starts to blow fresh sensitive wind slabs are likely to form.
  • Wind slabs may be poorly bonded to the underlying crust.

Avalanche Problems

Wind Slabs

Snowfall amounts were variable over the last 24 hrs. In places that did get enough snow to form wind slabs, these wind slabs will be poorly bonded to crusty surfaces and will be easily triggered.

Aspects: North, North East, East, North West.

Elevations: Alpine, Treeline.

Likelihood: Likely - Very Likely

Expected Size: 1 - 1.5
