Lo esencial

Start on small, mellow slopes and watch for signs of instability before approaching steeper or larger slopes.

Recent snow and wind have built reactive slabs, plus buried weak layers lurk.

    Cornices are large and fragile.

    Two crusts, buried in early February (facets on top) and March are still a concern, particularly in the Hurley area and zones to the north. Smaller avalanches or cornice falls have the potential to trigger an avalanche on these layers.

    1–2.5

    Recent storm snow and southwest winds continue to build reactive slabs. Avalanches are expected be larger and more likely on west through north facing (leeward) slopes.

Confidence

Moderate

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

Avalanche Summary

On Tuesday, north of Pemberton, numerous small (size 1) rider controlled storm slab avalanches were reported.

On Monday, northeast of Pemberton, a large (size 2) rider triggered wind slab avalanche was reported on a north facing slope in the alpine. Also, explosives avalanche control produced several small to large (size 1-1.5) avalanches, mostly cornices with some wind slabs. One of the cornice falls also stepped down to a deeper weak layer on the slope below.

Snowpack Summary

5 to 10 cm of new snow is expected by the end of the day on Thursday. Moderate to strong southwest wind through the day is expected to form deeper, more reactive deposits in leeward terrain.

This should all add up to 35 to 70 cm of recent storm 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.

Friday
Mix of sun and clouds. 3 to 4 cm of snow. 60 km/h southwest ridgetop wind. Treeline temperature -7 °C.

Saturday
Mix of sun and clouds. 40 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Terrain and Travel Advice

  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Be aware of the potential for large avalanches due to a buried crust.
  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
