Avalanche Summary

No new avalanches have been observed or reported in the past few days.

Snowpack Summary

10 to 15cm of new snow has fallen on top of 30 cm of soft snow and a generally supportive snowpack. We’re currently tracking a mid-November melt-freeze crust located in the mid-pack, though it has not shown any activity in our profiles.

There is a recently buried surface hoar layer in sheltered areas of the Bald Hills which is 10cm below the surface.

Weather Summary

Monday

Periods of snow will intensify through the day, producing 17cm of snowfall. Light ridge winds gusting to 45km/h and -5 °C.

Tuesday

Wednesday

Cloudy with sunny periods and isolated flurries producing 4cm of snowfall. Light ridge wind gusting to 30km/h and -6°C.

Terrain and Travel Advice

Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
Be alert to changing conditions throughout the day.

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.
