Give the storm snow time to bond before stepping out. Storm slabs will likely remain reactive to rider traffic.

Confidence

Moderate

Avalanche Summary

We suspect a natural storm slab cycle may have taken place at the peak of the storm Friday night.

Snowpack Summary

Up to 60cm of new snow has accumulated above 700m with extreme southerly wind impacting open terrain. This snow has fallen above a melt-freeze crust, and observations from the past few days suggest the snow may bond poorly to this crust. The crust is up to 10 cm thick at lower elevations and tapers down to 1 cm thick on shaded or high elevation terrain. Below this crust, the snowpack is generally strong and bonded.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Closely monitor how the new snow is bonding to the crust.
  • Be carefull around freshly wind loaded features.

Avalanche Problems

Storm Slabs

Storm slabs will likely remain reactive to rider triggering. The largest and most reactive slabs will be found on north and east aspects.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible - Likely

Expected Size: 1.5 - 2.5
