Regions

Yukon.

With wind stations rimed, we have uncertainty around the extent of recent wind affect on the snow. Make observations and assess surface conditions as you travel. Pay attention to the wind, watch for blowing snow and signs of instability like cracking or recent avalanches.

Confidence

Low - Uncertainty is due to the speed, direction, or duration of the wind and its effect on the snowpack.

Weather Forecast

Monday night: Increasing cloud, wind shifting southwest and building to strong, temperature rising to -16.

Tuesday: Flurries bringing a few cm of snow, strong southwest wind, high of -10.

Wednesday: Sunny, light southwest wind, high of -8.

Thursday: A mix of sun and cloud, moderate southwest wind, high of -5.

Avalanche Summary

We have received no reports of recent avalanche activity or signs of instability.

Snowpack Summary

MIN reports over the weekend describe great riding conditions at Fraser and White Pass summit. As we get into the week, surface snow could become more wind affected from outflows on Monday followed by strong southwest flow Tuesday. 

10-20 cm of recent snow appears to be bonding well to a variety of underlying surfaces including a crust that extends up to at least 1200 m on all aspects. Below this, the mid-pack is generally well-settled and strong in most areas. Weak facets (sugary snow) at the base of the snowpack appear to be rounding and bonding.

Terrain and Travel

  • Pay attention to the wind, once it starts to blow fresh sensitive wind slabs are likely to form.
  • Recent wind has varied in direction so watch for wind slabs on all aspects.
  • Pay attention to isolated alpine features as well as cross-loaded features at treeline.
  • Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind 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.
