Points saillants

While the likelihood of triggering a deep persistent layer may be decreasing, it is very difficult to predict where you will or will not trigger a large avalanche.

Continue to take a conservative approach while traveling in avalanche terrain.

    A weak layer near the base of the snowpack remains a concern despite lack of recent avalanche activity. Human triggering of this layer remains possible, especially in shallow areas with variable snow depths.

Moderate

Avalanche Summary

No recent avalanches have been reported in the region.

Please continue to share any observations or photos on the Mountain Information Network.

Snowpack Summary

The upper 30 to 50 cm of snow continues to settle and bond with mild temperatures. This sits over a generally weak and faceted mid and lower snowpack. A weak layer of facets and a crust buried in November is down 80 to 120 cm from the surface. The lower snowpack below this November weak layer is weak and highly facetted to the ground.

Treeline snow depths are roughly 140 to 160 cm.

Weather Summary

Sunday night

Cloudy with light snow, 0 to 5 cm. Light southwest ridgetop winds. Treeline temperatures 0 to -5 C.

Monday

Mostly cloudy with flurries, and trace amounts of snow. Light southwest ridgetop winds. Treeline temperatures -5 to -10 C.

Tuesday

A mix of sun and cloud, no precipitation. Light west ridgetop winds. Treeline temperatures -5 to -10 C.

Wednesday

A mix of sun and cloud, no precipitation. Light ridgetop winds. Treeline temperatures -5 to -10 C.

Terrain and Travel Advice

  • Uncertainty is best managed through conservative terrain choices at this time.
  • Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
  • Don't let the desire for deep powder pull you into high consequence terrain.
