In sintesi

Natural avalanches are possible; human-triggered avalanches are likely.

Use conservative terrain while the avalanche danger is elevated.

Problemi valanghivi

  • Storm Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità

    Dimensione
    1.5–2

    Storm slab size and sensitivity to triggering will likely increase through the day.

Confidence

Moderate

  • We are uncertain due to the timing, track, and intensity of the incoming weather system.
  • We are confident the likelihood of avalanches will increase with the forecast weather.

Avalanche Summary

No recent avalanches have been reported. We expect avalanche activity to increase with the forecasted weather.

If you get out into the backcountry, post a MIN!

Snowpack Summary

20 to 30 cm of new snow is expected by the end of the forecast period on Tuesday, with the highest amounts in the western part of the region (Allison Pass receiving closer to 5 cm). This new snow overlies a melt-freeze crust, moist snow, or isothermal conditions, depending on aspect and elevation.

The snowpack has undergone multiple warming and cooling cycles, forming a series of crusts interspersed with dense, rounded grains.

Snowpack depth decreases significantly below 1000 m.

Weather Summary

Monday Night

Cloudy. 5 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Tuesday

Cloudy. 15 to 25 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Wednesday

Mostly cloudy. 15 to 25 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -6 °C.

Thursday

Mix of sun and clouds. 2 to 10 cm of snow. 20 km/h northwest ridgetop wind. Treeline temperature -6 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Watch for fresh storm slabs building throughout the day.
  • As the storm slab problem worsens, the easy solution is to choose more conservative terrain.
  • Don't let storm day fever lure you into consequential terrain.
