Regions

Glacier.

Watch for signs of instability as you move into wind affected terrain.

Rugged and challenging travel with a shallow snowpack and widespread refrozen avalanche debris at low elevations.

Confidence

Moderate

Avalanche Summary

Warm weather and rain last week triggered a widespread spring like avalanche cycle with many avalanches gouging to ground in gully features and running full path. As temperatures have fallen and refrozen the surface natural avalanche activity has ceased.

Snowpack Summary

New snow sits over a robust surface crust that formed following recent warm weather. Be prepared for challenging travel over refrozen avalanche debris and shallow snowpack hazards below tree line.

The mid and lower snow pack is gaining strength and becoming less sugary.

Currently the snowpack is roughly 30cm below the previous record low.

Weather Summary

Still no major changes on the weather horizon; temperatures gradually falling and small increments of new snow through the week.

Tues: Flurries up to 9cm, low -6°C, moderate S winds, freezing level (FZL) 1700m.

Wed: Cloudy isolated flurries - trace, low -8°C high -4°C, light S winds, FZL 1400m.

Thurs: Cloudy isolated flurries - trace, low -10°C high -7°C,FZL 1100m.

Terrain and Travel Advice

  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.

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.
