Points saillants

Up to 20cm of snow is forecast for the next 24hrs as an upslope system moves into the region. Strong winds on Friday created new windslabs in alpine terrain. Assess the bond of new snow to the underlying crust as well as buried windslabs in higher elevations.

    Loose dry avalanches running on a crust may travel surprisingly far if snow amounts are as forecast.

Avalanche Summary

Nothing new observed in the past 24hrs but observations were limited.

Snowpack Summary

Strong winds combined with a few cm's of new snow overnight have made the wind affect in alpine areas much more pronounced. Expect windslabs along ridgelines on all aspects. Where the new windslabs are overlying a temperture crust from that week be sure to carefully evaluable to the bond with the underlying layers. On northern aspects the interface will be more of a storm snow interface down 20-40cm. With the new snow arriving Saturday be sure to evaluate the bond with the underlying snow surface. Where the new snow is overlying a thick MFC it will likely be more reactive so keep this in the forefront of your mind. Windslabs developed during this week will also be harder to locate so ensure you are feeling/evaluating these weakness as you travel.

Weather Summary

Freezing levels are forecast to drop to 1700m on Saturday as an upslope system moves into the region giving us 15-20cm of snow with generally light winds. Snow is forecast to start midday and continue into the evening on Saturday night. Daytime highs are forecast to be around -3C.

Terrain and Travel Advice

  • Even brief periods of direct sun could produce natural avalanches.
  • Avoid shallow snowpack areas, rocky outcrops, and steep terrain where triggering is most likely.
  • Wind slabs are isolated, but may remain reactive.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
