Points saillants

The past storm has increased avalanche danger across the forecast region.

Have patience and give this new snow time to settle before venturing into steep terrain.

Problèmes avalancheux

  • Wind Slabs

    Probabilité
    Possible
    Taille
    1–2

    New snow and wind are creating new wind slabs on south aspect terrain. Keep a sharp eye out for deep drifts and building pillows of snow on steep terrain near or below ridgetops.

  • Cornices

    Probabilité

    As the wind transports snow across open mountain tops, cornices will begin to grow and these tabs or cornice noses are fragile and will likely collapse with enough force to trigger slopes below.

Confidence

Moderate

  • We are uncertain about alpine conditions due to limited field observations.

Avalanche Summary

There have been no recent avalanches observed or reported.

We expect avalanche danger to increase slightly overnight on Friday with the arrival of new snow and wind.

If you head out, let us know what you are seeing by submitting a MIN report!

Snowpack Summary

New snow begun to accumulate on Friday, with up to 20 cm of accumulation forecast by Saturday morning. This new snow came in warm and is likely bonding to the old crust.

The mid and lower snowpack is generally strong.

In the alpine, the height of snow varies from 200 to 300 cm.

Weather Summary

A storm moving across western Newfoundland is expected to bring up to 15 cm of new snow to higher elevations, along with moderate to strong north to northwest winds. After the storm passes, unsettled dirty weather will continue, with light winds and occasional flurries.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Seek out wind sheltered terrain below treeline where you can avoid wind slabs and find great riding.
  • Avoid freshly wind-loaded terrain features.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
