Regions

Waterton Lakes, Waterton.

Bring your buff, as cool temps and increased winds will prevail on Wednesday and Thursday. Soft snow still exists in sheltered areas at treeline and below treeline.

Confidence

High

Avalanche Summary

A few natural windslab avalanches to size 1.5 were observed in the park over the last week.

Snowpack Summary

Up to 40 cm of snow has been redistributed into windslabs by moderate to strong SW winds. Surface snow remains unconsolidated below treeline and in sheltered treeline areas. This overlies the January drought layer which includes facetted snow on northerly aspects or a melt freeze crust below treeline and on steep solar slopes into the alpine. Generally, the snowpack has become weak and facetted.

Snowpack depths at treeline range from 75 - 150 cm.

Weather Summary

Cool with a subtle increase in temperature and wind through the forecast period.

Terrain and Travel Advice

  • Seek out wind sheltered terrain below treeline where you can avoid wind slabs and find great riding.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.

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.
