Regions

Glacier.

The storms are starting to roll in!

Expect reactive slabs to be forming in the alpine and exposed areas at treeline.

Confidence

Moderate

Avalanche Summary

A limited artillery avalanche control mission on Thursday produced small loose snow avalanches in steep terrain.

MIN reports have observed pockets of wind slab in the alpine.

Snowpack Summary

Up to 15cm of snow (and counting) is covering a surface hoar in sheltered treeline areas, a thin suncrust on steep solars aspects, and previous wind effect in open alpine terrain.

A rain crust is down 40-70cm in the snowpack, and exists up to approximately 2200m.

Weather Summary

A series of low pressure systems are set to march through the interior over the weekend, with a big punch on Monday.

Tonight Isolated flurries. Winds SW-20km/h. Alpine low -7°C, freezing level (FZL) 900m.

Sat Flurries, 10cm. High -4 °C. FZL 1500m. Wind SW 20 km/h gusting to 60.

Sun Flurries, 10cm. High -6 °C. FZL 1100m. Wind SW 25-50 km/h

Mon: Snow, 25-45cm. High -3°C, FZL 1400m. Wind SW 20 gusting to 75km/h

Terrain and Travel Advice

  • Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
  • Be cautious of buried obstacles, especially below treeline.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-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.
