Lo esencial

Warming and solar radiation will drive the avalanche danger in the coming days. Watch for conditions that change throughout the day, and be cautious of overhead hazards.This is our final forecast for the season and will expire Wednesday April 25.

Problemas de aludes

  • Cornices

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–2.5
    Warm temperatures and high freezing levels may weaken large and destructive cornices. Give them a wide berth if traveling above or below them.

  • Loose Wet

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Likely - Very Likely
    Tamaño
    1–2
    Warming and solar radiation over the next few days are expected to trigger loose wet avalanches, especially in steep, sun-exposed terrain. Loose wet avalanches can be pushy and entrain mass quickly.

Confidence

Moderate - Due to the number of field observations

Weather Forecast

A ridge of high pressure has developed for the forecast period bringing sunny skies and light ridgetop winds. The freezing level will rise to about 3400-3600m for Tuesday, Wednesday and Thursday.

Avalanche Summary

No new avalanches have been reported. In the coming days forecast warming and solar radiation are expected to trigger loose wet avalanches, especially in steep, sun-exposed terrain. Warming may also trigger destructive cornice failures.With information regarding avalanche activity and snowpack conditions becoming evermore sparse this time of year, we would very much appreciate it if you spend a moment to submit any observations you have to the Mountain Information Network here, even if it is just a photo. Thanks to those of you who have shared your recent observations!

Snowpack Summary

New snow and wind on the weekend formed fresh wind slabs in upper elevation lee terrain. The new snow overlies settled storm snow on shaded alpine slopes and a melt-freeze crust in most other areas. The mid and lower snowpack are generally strong and well bonded. At lower elevations you'll find a dwindling spring snowpack and melt-freeze conditions.
