Points saillants

The avalanche hazard is LOW. The deep basal weak layer is unlikey to get triggered but possible in thinner snowpack areas with rocky features.

    Thin snowpack areas is where you may be able to trigger this weakness that propagates out into a deeper snowpack area.

Weather Summary

Monday will warm up to -9c in the Alpine, along with sunny skies and 60km/hr winds from the NW. Only a few cm's of snow forecast for this week.

Terrain and Travel Advice

  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
  • Avoid steep terrain that is rocky and thin.
  • Avoid steep terrain, including convex rolls, or areas with a thin, rocky, or variable snowpack.

Confidence

High

  • We are confident due to a stable weather pattern.
  • The snowpack structure is well understood.

Avalanche Summary

No new avalanches have been observed or reported in a few days.

Snowpack Summary

4-8 cm of snow has fallen in the last 2 days and is now sitting on top of a widespread layer of surface hoar up to 2500m.

The warm temperatures last week developed a prominent surface crust on south aspects and a thinner crust on all aspect up into the lower alpine elevations. The snowpack is generally well settled with the November crust evident deeper in the snowpack down 150cm and an isolated surface hoar layer down 30-50cm. Both of these layers have been unreactive in tests and there has been no recent avalanche activity on these interfaces. Thin areas where the snowpack is highly variable are places where the deeper layers may be reactive.
