Lo esencial

Warmth is the main driver of avalanche hazard at the moment. Minimize your exposure to large slopes if the snowpack is becoming moist or wet.

    Looks like one more day of very warm temps. Watch for small loose wet avalanches and be aware that the large visor like cornices that overhang many ridge-tops are currently prone to failure.

  • Wet Slabs

    Tamaño

    As the snowpack is subjected to yet another day of significant warmth, the bond that fresh wind/storm slabs have with the underlying saturated snow and deeper crust could rapidly decay. Potentially large wet slabs may still be possible Tuesday.

Weather Forecast

Tuesday: Broken skies. Freezing level starting around 2500m, dropping to 1500m by days end. 1 to 6mm of precipitation expected, 1 to 8cm of snow possible. Treeline winds moderate SW/W, ridgetop winds strong SW/W.Wednesday: Scattered cloud cover. Freezing level starting at 1300m, rising to 1600m in the afternoon. No significant precipitation. Light W winds at treeline, moderate NW winds at treeline.Thursday: Freezing level starting around 1000m, rising to 1600m in the afternoon. Light NW/W winds at all elevations. Few clouds in the morning increasing to 80% cloud cover in the afternoon.

Avalanche Summary

No new avalanche activity reported from Saturday or Sunday. The last significant round of activity was from Friday which involved wet activity to size 2 on all aspects between 1600m and 2200m.

Snowpack Summary

3 to 10 cm lie above a hard crust created by barely freezing temperatures Saturday night. Below this crust 15 to 60cm of moist rain soaked snow can be found. Below this you'll find the mid-March crust/facet complex which is consistently down 40 to 70cm. Continued mild conditions are likely helping to strengthen the bond at this interface.
