Kernpunkte

Keep an eye on changing conditions and be prepared to dial back your objectives.

Brief periods of solar input combined with rising freezing level will increase the likelihood of avalanches

Lawinenprobleme

  • Wind Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    1–1.5

    Light snowfall and moderate wind has kept the wind slab problem active.

  • Cornices

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    2–2.5

    Rising freezing level and brief periods of solar input will increase the likelihood of cornices failing naturally.

  • Loose Wet

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible - Likely
    Größe
    1–2.5

    Wet loose avalanches will become likely during periods of solar input or when the snow surface feels slushy from rising freezing levels.

Confidence

Low

  • We are uncertain due to a limited number of field observations.
  • We are uncertain due to variable freezing levels.

Avalanche Summary

Small dry and wet loose avalanches continue to be observed in steep terrain throughout the region.

Last week several natural cornice falls were reported. Even without triggering slabs on the slopes below these cornices have resulted in size 2.5 debris.

Snowpack Summary

A crust exist on or near the surface on sun exposed slopes and on all aspects below treeline. This crust is expected to break down with the rising freezing level and brief periods of solar input. Dry snow can still be found on shaded slopes at treeline and above.

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, 2000 m in the Cariboos, and 2300 m in the North Monashees.

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

Weather Summary

Sunday Night

Partly cloudy. 2 to 5 mm of precipitation as snow or rain at treeline. 20 km/h south ridgetop wind. Treeline temperature 0 °C. Freezing level 1900 m.

Monday

Mix of sun and clouds. 2 to 5 mm of rain at treeline. 40 km/h southwest ridgetop wind. Treeline temperature 2 °C. Freezing level 2200 m.

Tuesday

Mostly cloudy. 10 to 15 cm of snow. 40 km/h west ridgetop wind. Treeline temperature -5 °C.

Wednesday

Mostly cloudy. 1 to 3 cm of snow. 30 km/h northwest ridgetop wind. Treeline temperature -4 °C.

Terrain and Travel Advice

  • Pay attention to isolated wind affected features in the alpine, as well as cross-loaded features at treeline.
  • Loose avalanches may start small, but they can grow and push you into dangerous terrain.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
