Lo esencial

Good skiing with "dust on crust conditions", but pay attention to the solar radiation and how quickly the day is warming up.

    10-20 cm of recent storm snow sluffing on harder bed surfaces below. With minimal wind expect a dry loose problem, but may act as a small slab if winds pick up.

    The forecast is for sunny periods on Tuesday and solar radiation could be strong enough to create loose wet avalanches in the storm snow on southerly aspects.

Terrain and Travel Advice

  • Even brief periods of direct sun could produce natural avalanches.

Confidence

Moderate

Avalanche Summary

Several small loose dry avalanches in the storm snow reported out of immediate lees in the alpine.

Snowpack Summary

There is 10-20 storm snow at treeline over top of well developed crusts on solar aspects (to ridgetop), and on crusts at all aspects treeline and below. On north facing alpine slopes there is 20-30 cm of dry snow over firmer surfaces. A settled mid-pack sits over the Jan facets down 90 to 150cm, with a well settled lower snowpack below.

Weather Summary

A ridge of high pressure will begin building on Tuesday and be well established by Wednesday morning. Winds are forecast to be light on Tuesday with Freezing Level rising to 2000m.
