Points saillants

Cold conditions are keeping storm slabs reactive for longer, especially at upper elevations.

Back off of steep terrain if you notice signs of instability like cracks in the snow surface.

    Recent storm snow and moderate to strong winds have formed storm slabs that remain possible to human trigger on Sunday. Danger will be greatest in open, higher elevation terrain.

Terrain and Travel Advice

  • Start with conservative terrain and watch for signs of instability.
  • Investigate the bond of the recent snow before committing to your line.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.

Confidence

Moderate

  • Uncertainty is due to the limited number of field observations.

Avalanche Summary

Reports have been limited. Natural and human triggered avalanche activity was reported on Friday near Cypress.

Snowpack Summary

Recent storm snow has been redistributed by variable direction, moderate winds at upper elevations and remains unconsolidated in sheltered terrain.

Roughly 120 to 140 cm of settling snow sits on the December 16 crust.

At lower elevations this recent snow overlies bare ground.
