Weather Forecast

Clear skies should hold for most of Tuesday. On Wednesday a pulse of Pacific moisture will move through the region bringing 10 to 15cm of snow at higher elevations. Ridge top winds are forecast to be moderate from the west on Tuesday, switching to strong and southwesterly with Wednesday's system. Freezing levels will be around 2200m on Tuesday, and then drop to about 1600m for Wednesday and Thursday, then rising again to 3000m on Friday

Avalanche Summary

No new avalanches have been reported. Forecast sunny skies may increase the likelihood of loose wet avalanches on solar aspects, as well as cornice failures.

Snowpack Summary

Snow surfaces can best be described as variable. Melt-freeze conditions can be found on solar aspects in the alpine, and on all aspects at lower elevations. On high north-facing terrain, you may find stubborn old wind slabs and surface facets. The snowpack is generally strong and well settled. However, be aware that cornices may become weak with daytime warming.
