Description:
The weather is due to settle today following several days of storm activity. Snowfall totals will be substantial on the Divide with, less in the East. This snow has been redistributed by severe gales from the North right through to the South most recently. The new snow has landed on slippery crusts in many places and as a consequence, the bond should be treated with suspicion. Stay clear of ridge line entry points and steep roll overs if you encounter areas of firm wind driven snow and watch out for cross loaded slopes. If you are finding decision making challenging, remain on low angled ground and give slopes exposed to terrain traps a wide berth.

Recent Avalanche Activity

Recent Avalanche Activity
A local heli ski operator has reported a size 2 slab avalanche which ran naturally during the past few days - SE aspect,2100m.Control work on Wednesday at a local ski field produced a number of small slab (size 1) results lee to the S1/4 above 1700m.

Current Snowpack Conditions

Current Snowpack Conditions
Significant snowfall has occurred over the past few days especially, in the West of the region. During the same period, we have experienced severe gales from the Westerly 1/2. Moderate to strong Southerly winds transported snow on Wednesday. Areas of wind slab are likely to have developed on a range of aspects but particularly on East and North facing slopes above 1600m.This loading is sitting on hard crusts in many areas and as a consequence, may take some time to fully bond. The mid and lower pack is currently reasonably stable helped, by recent rain and warmer temperatures.

Sliding Danger

Slide For Life
Hard,fast rain crusts are widespread below about 1700m. They may now be covered with a thin layer of new snow but the underlying crust will still be very slick in many places. Be prepared for variable snow conditions at lower elevations and keep your speed under control.Ski crampons are a good addition to your pack at the moment.
