Regions

Glacier.

Warm temps & rising freezing levels are expected on Sunday & Monday which could increase the likelihood human triggered activity.

Beware of early season hazards at tree-line & below.

Confidence

Low

Avalanche Summary

No new avalanches observed on Saturday.

However, an avalanche cycle triggered by wind and rain peaked on Thursday night. Several avalanches up to size 3.0 were observed in the highway corridor, some running well into the bare ground on lower elevation fans.

Snowpack Summary

A small surface crust exists at tree-line.

Up to 45mm of rain from the last storm saturated the snowpack into the alpine - this mostly came as heavy snow above 2200m, but was accompanied by strong-extreme SW winds.

There may be a lingering layer of buried surface hoar in the alpine. This could be up to 80cm deep in lee areas.

Weather Summary

A weakening system passes our area tonight, giving snow flurries into Saturday morning.

Tonight: Trace precip. Alpine Low -3°C. Freezing level (FZL) 1700m. Light Southwest ridge winds.

Sun: Isolated wet Flurries. Alpine High +2 °C. FZL 2500m. Light South wind.

Mon: Isolated flurries. Low -3 °C, High +1 °C. FZL 2200m. Light South wind.

Tues: Isolated flurries. Low -5 °C, High -2 °C. FZL 1800m. Light West wind.

Terrain and Travel Advice

  • Snow is accumulating at higher elevations, despite lower elevations being almost snow-free.

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.
