In sintesi

Avalanche danger is improving as wind, snowfall, and temperatures have decreased.

There are still some avalanche problems to dodge. Scroll down to read the whole forecast.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–2

    Small pockets of wind slab may still avalanche under the weight of a human.

  • Cornices

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Likely
    Dimensione
    1.5–2.5

    Cornices are large and fragile. Even a small period of sun and warming may be enough to cause a cornice to fail.

  • Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    2–3.5

    Two crusts, buried in early February (facets on top) and March seem to be gaining strength. It's still smart to avoid thin, rocky areas on steep slopes, and avoid exposing yourself to slopes below large cornices.

Confidence

Moderate

  • We are uncertain about how quickly persistent slabs are gaining strength.

Avalanche Summary

Both Thursday and Friday, large to very large (size 2-3) natural storm slab avalanches were reported near Anderson Lake.

The most recent avalanche on a persistent weak layer was reported on Monday, March 23 when an explosive triggered cornice fall stepped down to basal facets in a steep, rocky start zone.

Snowpack Summary

Expect to find 35 to 70 cm of settling snow over a widespread, thick and hard crust below about 1800 m, and old wind-affected snow at upper elevations.

Two crusts, buried in early February and March are still a concern, particularly in the Hurley area and zones to the north. Expect to find them around 1-1.5 meters below the snow surface. Of the two, only the early February crust has been reported to have loose, sugary facets on top.

Weather Summary

Sunday Night

Mostly clear skies. Up to 3 cm of snow. 20 km/h northwest ridgetop wind. Treeline temperature -11 °C. Freezing level falling to valley bottom.

Monday

Sunny. 10 km/h northwest ridgetop wind. Treeline high -8 °C. Freezing level rising to 1100 m.

Tuesday

Mix of sun and clouds. 30 km/h southwest ridgetop wind. Treeline temperature -8 °C.

Wednesday

Mix of sun and clouds. 1 to 3 cm of snow. 40 km/h south ridgetop wind. Treeline temperature -6 °C.

Terrain and Travel Advice

  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • Avoid terrain traps such as gullies and cliffs where the consequence of any avalanche could be serious.
