Avalanche Summary

We haven’t received any reports of avalanches in the past few days. If you are headed into the backcountry, please consider sharing a MIN report.

Snowpack Summary

A hard melt-freeze crust is found on sun-exposed slopes to the mountain tops and all aspects up to around 1400 m. The crust will transition to wet snow with daytime warming. Dry, settled snow exists on shaded aspects in the alpine.

A weak layer of faceted grains and/or surface hoar crystals may be found around 40 to 80 cm deep, particularly on northerly alpine slopes. The weak layer may be close to a hard melt-freeze crust from early April.

Weather Summary

Tuesday Night

Clear skies. 10 to 20 km/h northeast ridgetop wind. Treeline temperature -1 °C.

Wednesday

Clear skies. 10 km/h east ridgetop wind. Treeline temperature 2 °C. Freezing level rising to 1600 m.

Thursday

Clear skies. 20 km/h east ridgetop wind. Treeline temperature 3 °C. Freezing level rising to 1700 m.

Friday

Clear skies. 30 to 40 km/h east ridgetop wind. Treeline temperature 1 °C. Freezing level rising to 1500 m.

Terrain and Travel Advice

  • The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • If triggered loose wet avalanches may step down to deeper layers resulting in larger avalanches.

Avalanche Problems

Loose Wet

Loose wet avalanches may release when the sun is strong. Cornices will also weaken with daytime warming. Watch your overhead exposure during the heat of the day.

Aspects: South East, South, South West, West.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
