High Alpine: Above 2000m
Alpine: 1000 to 2000m
Low Alpine: Below 1000m
Description:
New snow fell above 1500m (20cm) Thursday night. This fell with winds from the NW, and then changed to the SW that night. Watch for wind slabs that formed overnight Thursday, especially in the higher altitudes in the northern Darrans. Snow and winds overnight Saturday into Sunday am will increase the danger to considerable on Sunday. This should stabilize quickly.

Alpine level
High Alpine: Above 2000m
Alpine: 1000 to 2000m
Low Alpine: Below 1000m
Description:
From 2000m below watch for isolated wet slab releases. The snow pack has been well rain soaked from a series of warm NW’ters. Be observant during your travels, watch for obvious glide cracks, and be aware of their run outs. This includes the valley floors under big cliff faces.

Recent Avalanche Activity

Recent Avalanche Activity
No avalanches were observed within the new snow from the front that passed through overnight Thursday. There is still lots of evidence of areas where the snowpack is gliding, with cracks and buckling of the snowpack wide spead below 2000m

Current Snowpack Conditions

Current Snowpack Conditions
A spring snowpack dominates below 2000m. Above this the snowpack is still mostly cold and dry. Thought 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 are clear of snow at present. This can change rapidly.

Mountain Weather

Mountain Weather
Tomorrow is forecast to dawn clear. Winds will turn to the NW and strengthen to Severe Gale ahead of another system that crosses the park on Sunday morning. We are expecting 40+cm of snow above 1500m with lesser amounts to 1000m, tapering of in the east. Monday looks good with another storm forecast to arrive Tuesday afternoon.

Sliding Danger

Slide For Life
A clear night with cool temps will help freeze the snowpack to low elevations. This should soften quickly.
