Regions

Long Range Mountains, Corner Brook, Gros Morne, Northern Peninsula.

Low hazard doesn't mean no hazard.

Watch for isolated pockets of wind slab and be alert to open creek crossings, holes, and slippery surfaces.

Confidence

Moderate

Avalanche Summary

A natural avalanche cycle occurred early last week after the rain event. No recent avalanche activity has been observed.

Watch for other hazards like creek crossings, holes, and slippery surfaces.

Snowpack Summary

Up to 10 cm of new snow arrives on Sunday. This new snow is falling on bare ground in many areas, or up to 40 cm of soft slab in north and northeast-facing bowls and gullies. Below this is a firm crust.

Significant melt has occurred over the past month and many areas are below the threshold for avalanches.

Weather Summary

Saturday Night

Increasing cloud cover. 20 to 50 km/h southwest wind. Alpine temperature -4 °C.

Sunday

Cloudy with up to 10 cm of new snow. 50 to 100 km/h southwest wind. Alpine temperature -2 °C.

Monday

A mix of sun and cloud with light flurries. 40 to 60 km/h west wind. Alpine temperature -6 °C.

Tuesday

A mix of sun and cloud. 30 to 50 km/h west wind. Alpine temperature -5 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Avoid travelling on slopes below cornices.
  • Avoid slopes that sound hollow or drum-like.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.

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.
