With a bit recent new snow and wind, keep an eye out for wind slab formation in the lee of ridge crests.

Confidence

High

Avalanche Summary

No significant avalanches have been reported in the past few days. If you head out in the backcountry, let us know what you are seeing by submitting a report to the Mountain Information Network.

Snowpack Summary

5 to 15 cm of new snow has fallen on wind-pressed surfaces in the alpine and crust on solar aspects around treeline. Soft older snow may be found in shady, wind-sheltered areas. Weaknesses in the mid and lower snowpack are unlikely to produce avalanches under the current conditions. A weak layer of surface hoar/crust/facets buried in early January is now over 1 m deep in most areas, and has not produced avalanche activity for several weeks. The lower snowpack consists of basal facets, particularly in thin snowpack areas.

Weather Summary

Saturday Night

Mostly cloudy, isolated flurries accumulation 1-4cm, light northwest wind, treeline temperature around -6 °C.

Cloudy with sunny breaks, no significant precipitation, light to moderate southwest wind, treeline temperature around -5 °C.

Monday

Mix of sun and cloud, no precipitation, moderate northwest wind, treeline temperature around -6 °C.

Tuesday

Mix of sun and cloud, moderate southwest wind, treeline temperatures around -6 °C.

Terrain and Travel Advice

  • Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
  • Pay attention to isolated alpine features as well as cross-loaded features at treeline.
  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
