Regions: McGregor.

Continuously assess conditions as you move through terrain. Storm and wind slabs could build throughout the day. Use extra caution at treeline where storm slabs could overlie surface hoar and facets.

Confidence

Moderate

Avalanche Summary

Observations in the region are limited. If you are out in the backcountry please consider filling out a Mountain Information Network report.

Snowpack Summary

A series of storms over the past few days has brought 40 to 70cm of new snow with strong southwest winds. This new snow has likely formed wind slabs in exposed terrain at higher elevations and buries a variety of surfaces at treeline including facets, surface hoar, a crust and bare ground. At lower elevations most of this recent precipitation would likely have fallen as rain.

Weather Summary

Tonight

Flurries bringing around 5cm of new snow with strong west-southwest winds. Temperatures at 1600m around -5.

Saturday

Stormy weather bringing 15 to 30cm with strong southwest winds. Freezing levels rising to around 1000m.

Sunday

A mix of sun and cloud with the possibility of light flurries bringing trace amounts of new snow. Low of -15 at 1600m and light winds from the northwest.

Monday

Mostly sunny with no new snow expected. Light winds and a low of -18 at 1600m.

Terrain and Travel Advice

  • Watch for fresh storm slabs building throughout the day.
  • Make observations and assess conditions continually as you travel.
  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.

Avalanche Problems

Storm Slabs

The areas of greatest concern are sheltered slopes at treeline where storm slabs could overlie surface hoar which could result in larger and more sensitive slabs. In exposed higher elevation terrain wind slabs will likely be found. Most below treeline terrain is below threshold but steep slopes with smooth ground surfaces may still be capable of producing avalanches.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Likely

Expected Size: 1.5 - 2.5
