Another front this afternoon is forecast to drop another 35mm/cm with gale winds from the west. The snowline will fluctuate from 1000m to 1600m the drop again overnight. There is plenty of snow above 1800m to blow around and form wind slab. With the rise in freezing level and heavy rain forecast for the weekend expect the avalanche danger to stay the same or increase this weekend.

Alpine level
High Alpine: Above 2000m
Alpine: 1000 to 2000m
Low Alpine: Below 1000m
Description:
Colder temperatures over the last couple of days appear to have locked up most of the wet slabs. There may be random isolated natural occurrences so limit you time underneath cliff bands and areas with obvious glide cracks. This will increase over the weekend with heavy rain and high temperatures forecast.

Recent Avalanche Activity

Recent Avalanche Activity
Cloud has limited observations in the high alpine. There is still lots of evidence of areas where the snowpack is gliding, with cracks and buckling of the snowpack wide spread below 2000m

Current Snowpack Conditions

Current Snowpack Conditions
A spring snowpack dominates below 1800m. Above this the snowpack is still mostly cold and dry. Though the warm season means there is little snow below 1600m, the high alpine is as usual chocker.
The Kepler and the major passes on the Routeburn and Milford have a dusting of snow at present, with more forecast in the next couple of days.

Mountain Weather

Mountain Weather
Another fast moving front will pass over the park tonight before a brief clearance on Friday afternoon/Saturday am. There is a high chance of heavy rain/snow Saturday pm into Sunday before a more settled spell. Winds will be the usual mix of NW swinging to SW then back again. Freezing levels are about 1200m with a rapid size to above 3000m on Saturday.
