Current Snowpack Conditions

Current Snowpack Conditions
There have been significant snowfalls early season during May. Over the last 2 weeks significant amount of rain has fallen to upper elevations in the park and significant snow ablation has occurred so little snow exists below 1800m.
Cool overnight temperatures on Friday night saw the first freeze of this soggy snow pack at upper elevations for some time! New snow from the north east and then the west will be deposited to southern and eastern aspects during Sunday Monday and Tuesday down to 1600m.

Mountain Weather

Mountain Weather
Light wind from the west tending south late in the day with a freezing level of 1800m and snow forecasted to 1500m easing during day.
