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.

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.

Problems

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
