Regions

Glacier.

Be prepared for a firm surface early in the morning, but get your travelling done before the crusts soften to slop in the afternoon.

Cornices are huge and don't like the extreme temperature fluctuations at this time of the year. Give 'em a wide berth and don't linger below them!!

Confidence

Avalanche Summary

Sunshine and warm temperatures triggered a small loose wet avalanche cycle from steep terrain over the weekend.

A widespread, natural avalanche cycle occurred up to size 4.0 on Mar 19-20 during the atmospheric river filling the valley bottoms with huge debris piles in many locations. Check out pics from this exceptional avalanche cycle in the MIN Reports.

Snowpack Summary

Flurries on Monday night / Tuesday brought a dusting of snow over a widespread crust. Very high elevation north facing slopes may still hold dry snow.

A thick rain crust from the March atmospheric river sits 20-50cm below the surface.

Below treeline the surface varies from isothermal sticky snow to refrozen tree bombs and huge debris fields from the massive avalanche cycle in March.

Weather Summary

Increasing sun and no new snow/rain as the week moves along, with daily freezing levels (FZL) increasing into the weekend.

Tonight Clear periods. Alp low -9°C. Winds W 15 gusting 40Km/h. Freezing level 700m

Wed Sun & cloud. Alp High -4°C. Wind W 10-25km/h. FZL 1800m

Thur Sun & cloud. Alp High -1°C. Light ridge winds. FZL 2100m

Fri Sunny. Alp High 5°C. Light ridge winds. FZL 2700m

Terrain and Travel Advice

  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
  • Avoid travelling on slopes below cornices.
  • Approach lee and cross-loaded slopes with caution.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.

Cornices

Cornice Fall is the release of an overhanging mass of snow that forms as the wind moves snow over a sharp terrain feature, such as a ridge, and deposits snow on the downwind (leeward) side. Cornices range in size from small wind drifts of soft snow to large overhangs of hard snow that are 30 feet (10 meters) or taller. They can break off the terrain suddenly and pull back onto the ridge top and catch people by surprise even on the flat ground above the slope. Even small cornices can have enough mass to be destructive and deadly. Cornice Fall can entrain loose surface snow or trigger slab avalanches.
