Avalanches are unlikely but a dusting of snow over a hard crust can make for difficult travel and increase the consequences of slips or tumbles on steep terrain. 

Summary

Confidence

Moderate - Forecast snowfall amounts are uncertain.

Weather Forecast

Saturday night: Clear. Strong northwest wind. Treeline temperature around -5.

Sunday: A mix of sun and cloud. Light northwest wind. Treeline high temperatures around -6.

Monday: Overnight snow 10-15 cm then clearing. Light northwest wind. Treeline high temperatures around -7.

Tuesday: A mix of sun and cloud. Strong northwest wind. Treeline high temperatures around -2.

Avalanche Summary

A thick surface crust has effectively eliminated avalanche concerns in the region.

Snowpack Summary

A skiff of new snow sits over a thick, supportive surface crusts at all elevations.

Treeline snow depths in advance of the storm were around 80-100 cm but rain has eroded some of this. Much of treeline and almost all below treeline elevations are still below threshold depths for avalanches.

Terrain and Travel

  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • A crust on the surface will help bind the snow together, but may make for tough travel conditions.
