Increasing winds might develop fresh, sensitive wind slabs on south and west slopes. Avoid areas where snow feels stiff or slabby.

Moderate

Avalanche Summary

On Sunday, avalanche control produced several explosive-triggered storm slab avalanches size 1.5 to 2.5, and numerous dry loose avalanches, size 1 to 1.5, on northeast aspects at treeline.

On Saturday, several natural storm slab avalanches were reported up to size 2.5 on northerly aspects.

We expect new snow will remain reactive to skier traffic on Tuesday, anywhere winds have formed slabs and fast-moving dry loose avalanches in steep terrain.

Snowpack Summary

Storm snow totals range from 40 to 70 cm, with deeper deposits in wind-loaded areas. Northeast winds increasing on Monday evening might develop fresh wind slabs on south and west facing slopes.

The storm snow has bonded poorly to the old snow surfaces, which includes melt-freeze crusts on sun-exposed slopes, large surface hoar or facets in sheltered areas, and wind-affected snow in exposed terrain at ridgelines.

The lower snowpack is strong and bonded.

Weather Summary

Cloudy with light flurries, 1 to 3 cm. 10 to 25 km/h east ridgetop wind. Treeline temperature -26 °C.

Wednesday

Mainly sunny. 10 to 25 km/h southwest ridgetop wind. Treeline temperature -16 °C.

Thursday

Clear. 10 km/h southwest ridgetop wind. Treeline temperature -14 °C.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Use small, low consequence slopes to test the bond of the new snow.
  • Be aware of the potential for remote triggering and large avalanches due to buried surface hoar.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.

Problems

Storm Slabs

An icon showing Storm Slabs

The new snow has bonded poorly to underlying layers. Avoid wind loaded areas where more cohesive slabs may be primed for human triggering. Carefully manage sluffing in steep terrain.
