Start early and time your exposure to be out of serious avalanche terrain during the hottest parts of the day.

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

Some dry snow may still remain on shady northerly aspects in the high alpine.

A typical spring diurnal pattern is in effect: daytime warming melts the upper snowpack, while overnight cooling usually forms a crust at higher elevations. Freezing levels are expected to soar to 3000 m over the next couple of days, with very limited cooling and crust recovery overnight.

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

Weather Summary

Clear. 15 to 20 km/h southeast ridgetop wind. Treeline temperature 3 °C. Freezing level 2500 m.

Friday

Sunny. 10 to 25 km/h southeast ridgetop wind. Treeline temperature 8 °C. Freezing level 3000 m.

Saturday

Mix of sun and cloud. 10 to 15 km/h north ridgetop wind. Treeline temperature 9 °C. Freezing level 3000 m.

Sunday

Mostly sunny. 20 km/h north ridgetop wind. Treeline temperature 8 °C. Freezing level 2800 m.

Terrain and Travel Advice

  • Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
  • Use appropriate sluff management techniques.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Start your day early and be out of avalanche terrain during the heat of the day.

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.
