    The new snow will likely build storm slabs throughout the forecast period.

Confidence

Moderate

  • We are uncertain due to a limited number of field observations.
  • We are uncertain about forecast snowfall amounts.

Avalanche Summary

A few storm slabs and several wet loose avalanches were reported on Sunday, up to size 1.5.

Snowpack Summary

Up to 20 cm of new snow will fall by the end of the day on Tuesday. This falls on a widespread crust from previous warm temperatures and sun up to 2100 m.

A hard crust is buried 30 to 70 cm deep, but may remain exposed in wind-scoured alpine terrain. It extends up to at least 1500 m in the Rockies, and 2000 m in the Cariboos.

Below the crust, the snowpack is strong and well-bonded.

Terrain and Travel Advice

  • Storm slab size and sensitivity to triggering will likely increase through the day.
  • Expect slab conditions to change drastically as you move into wind-exposed terrain.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
