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

Avalanche hazard exists primarily in alpine bowls, gullies and ridgelines where the snowpack has survived the recent rain, and new snow is being wind loaded over a slippery crust.

Confidence

Moderate

Avalanche Summary

No new avalanches have been reported. Wind slabs sitting on a crust are expected to be reactive both naturally and to rider triggers.

Snowpack Summary

10 to 30 cm of recent snow sits over a thick crust or directly on the ground in areas where the snowpack was washed away by the recent rain. In exposed terrain, the recent snow has been redistributed into lee features by strong west winds.

In the high alpine, greatest snowpack depths are in the range of 1 m. Elsewhere, most areas are below threshold for avalanches.

Weather Summary

Snowsqualls, up to 10 cm concentrated around Gros Morne. Southwest wind 60-70 km/h. Alpine temperature -12 °C.

Saturday

Snowsqualls up to 5 cm in the morning then clearing to a mix of sun and cloud. West wind 30-50 km/h switching southwest and easing overnight. Alpine temperature -6 °C.

Terrain and Travel Advice

  • Winter conditions may exist in gullies, alpine bowls, and around ridgelines.
  • Avoid freshly wind loaded terrain features.
  • Wind slabs may be poorly bonded to the underlying crust.

Avalanche Problems

Wind Slabs

Strong west winds are loading new snow into leeward features in wind-exposed terrain. Wind slabs will be especially reactive where they sit over a slippery crust.

Aspects: North, North East, East, South East, South.

Elevations: Alpine, Treeline.

Likelihood: Likely

Expected Size: 1 - 1.5
