Regions

Glacier.

Heavy rain to treeline has not made travel conditions any friendlier. Freezing levels are forecast to drop overnight with a bit more snow to come, but rugged travel at lower elevations will likely persist as the biggest hazard until at least the weekend.

Confidence

Low

Avalanche Summary

There were several avalanches picked up by our avalanche detection network on Thursday. None were large enough to make deposits visible from the road, but may have been up to size 2.

Snowpack Summary

Up to 35mm of rain has saturated the snowpack into the alpine - this may be falling as snow above 2200m.

There is a buried layer of surface hoar in open areas at treeline and in the alpine. This could be up to 80cm deep in lee areas after the storm.

Weather Summary

A cooling trend is forecast overnight, hopefully we will start to see some snow instead of rain treeline and below...

Tonight: Flurries ~10cmcm. Freezing level (FZL) 1200m. Wind: West mod-strong.

Fri: Isolated Flurries. Alpine High-6 °C. FZL 1300m. Winds: light-mod SW.

Sat: Flurries ~10cm. Alpine Low -5 °C, High -2 °C. FZL 1900m. Mod SW wind.

Sun: Isolated flurries, FZL 2400m

Terrain and Travel Advice

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

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.
