Regions

Waterton Lakes, Waterton.

Snowfall and winds are expected to increase in the coming days. Look out for evidence of recent wind transport, which could contribute to previously existing wind slabs in leward terrain features.

Confidence

Moderate

  • Forecast snowfall amounts are uncertain.

Avalanche Summary

Several natural wind slab avalanches observed, and isolated natural loose snow avalanches observed over the past few days.

Snowpack Summary

Surface layers include up to 40 cm of wind effected snow. Under which sits a melt freeze crust. Below this crust, lies 50 cm of settling snow. The lower snowpack consists of refrozen rain effected layers, which is still moist at ground in places.

Saturday

Flurries, up to 6 cm of snow. Low of -3 °C, High of -2 °C. SW winds gusting to 50 km/h. Freezing level at 1700 m.

Sunday

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.

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.
