Summary

Confidence

Fair - Due to the number and quality of field observations

Weather Forecast

On Wednesday a pulse of Pacific moisture will move through the region bringing a possible 10 to 15cm of snow at higher elevations. Ridge top winds are forecast to be moderate and southwesterly with Wednesday's system, then switching to South on Thursday and Friday.  Freezing levels should drop to about 1600m for Wednesday and Thursday, then rising 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.
