Climbers should be aware of windslabs along and above routes. Even small avalanches can have large consequences in gullied terrain or if an avalanche occurs while climbing.

Summary

Confidence

Moderate

Avalanche Summary

Natural avalanches have tappered off but with winds increasing tomorrow, watch for slabs to become more reactive and loose dry avalanches over steeper climbs.

Snowpack Summary

Windslabs dominate the landscape in this region with drummy hollow slabs the norm. These slabs are either overlying weak facetted bases or a rain crust at lower elevations. When the new snow falls later in the week watch for thin new windslabs building overlying the previous layers.

Weather Summary

Winds will again be strong in this area on Wednesday with gusts over 80km/hr forecast out of the west. As the front pushes out, some new snow will fall with total amounts up to 5cm. Winds will be light on Thursday and Friday with temperatures more seasonal.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Small avalanches may cause climbers to fall or belayers and gear to become buried.
