It's a good time to explore more complex terrain, start your day early and end early.

Be sure to verify conditions before committing to steep slopes and back off if the snow is wet and slushy.

Moderate

Avalanche Summary

No recent avalanche reports, but observations are very limited.

If you're heading into the backcountry, please share what you see on the Mountain Information Network.

Snowpack Summary

Up to 10 cm of recent snow may be found on northerly aspects in the alpine.

A typical spring diurnal pattern is in effect: daytime warming moistens the upper snowpack, while overnight cooling usually forms a hard crust at higher elevations.

Lower elevations may not refreeze and are experiencing an all-melt, no freeze scenario and melting out quickly.

Friday

Sunny. 10 to 15 km/h south ridgetop wind. Treeline temperature 8 °C. Freezing level 2900 m.

Saturday

Mix of sun and cloud. Mostly light ridge wind west ridgetop wind. Treeline temperature 8 °C. Freezing level 3000 m.

Terrain and Travel Advice

  • Investigate the bond of the recent snow before committing to your line.
  • Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.

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.
