Regions

Lizard-Flathead, Akamina, Flathead, Lizard.

The snowpack is generally stable; continually assess as you travel.

Watch for isolated wind slabs in extreme terrain.

Confidence

Moderate

  • We are uncertain about how the timing or intensity of solar radiation will affect the snowpack.

Avalanche Summary

No new avalanches were reported.

Going forward, small wind slab avalanches may be triggered in isolated terrain features like steep, extreme terrain and near the base of headwalls, and spill zones.

Snowpack Summary

Roughly 5 to 10 cm of new snow has buried various surfaces including a melt-freeze crust on solar aspects and wind-affected snow elsewhere.

The recent snow sits on a thick crust. Below it, up to 50 cm of rain soaked snow sits on another crust (1 to 10 cm thick) from early March.

Persistent weak layers may linger within the top 150 cm of the snowpack. These are unlikely to trigger in most areas as a result of the thick crust bridging over them.

The mid and lower snowpack is strong in most areas. Snowpack depth tapers rapidly at lower elevations.

Terrain and Travel Advice

  • Be alert to conditions that change with elevation and sun exposure.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Wind slabs are isolated, but may remain reactive.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
