Lo esencial

Good skiing can be found on low angle smooth features. Sunday evening things look to be changing with a nice size storm coming our way.

    This sits upon weak faceted crystals, sun crust or a dense layer that are perfect for slab avalanches. North aspects may be more susceptible to triggering as these areas did not experience a strong melt-freeze cycle like the solar sides did.

Confidence

Moderate

Avalanche Summary

Filed teams up in the Robertson valley today noted a couple fresh slabs size 2.5 that ran to valley bottom covering up a skin/decent track from yesterday.

A few new solar avalanches in the alpine on West aspects to size 2.5 also observed up in the burstall pass zone.

Otherwise good evidence of a widespread avalanche cycle from a week ago.

Snowpack Summary

5-10cm of settled snow sits on the surface. Where the sun was shinning there is now a mellt freeze crust to contend with. The main concern right now is the persistent slab 15-30cm thick that is resting on the Jan 30 interface made of facets, sun crust or another dense layer. The mid and lower snowpack is primarily facets. Human triggering remains possible due to the dense slab overlying a lot of weak facets. Forecasters have little confidence in the snowpack. Travelling at lower elevations involves ski penetration to ground if you leave any established trail.

Weather Summary

Saturday will be mostly cloudy.

Day time high of -6 and15-25km/h Southwest winds.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Keep in mind that human triggering may persist as natural avalanches taper off.
  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
