The avalanche forecasting season for the region has now ended and will start up again next June.

It is possible for avalanche conditions to exist whenever there is snow on the ground. We advise using caution in steep areas and on slopes lee to prevailing storms for at least a few days following fresh snowfall. High radiation (sun effect) will soften the snow during the day, expect some wet slide activity especially through the hottest part of the day, of greatest concern after new snow. NE – W aspects will usually soften the quickest and the most, so proceed with caution and be prepared to change plan.

During significant rain fall, spring avalanches may reach valley floor. Ice axes and crampons are a must in spring as conditions become firm during nighttime cooling.

The Aoraki/Mount Cook region avalanche forecast runs year round and is a good indicator of the avalanche hazard in the higher regions of the Southern Alps.

For further avalanche information please contact the local Department of Conservation office or check the Aoraki/Mount Cook region.

Enjoy your summer.

Current Snowpack Conditions

Current Snowpack Conditions
The snow pack has transitioned into a spring snow pack. Strong when frozen! Not so strong when not. Care is required when temperatures are warm and rain is falling at all elevations. Significant snow ablation has occurring in the park in the last 2 weeks due to warmer temperatures and rain. Good overnight clearances and lower freezing level will assist with creating firm snow in the morning.

Mountain Weather

Mountain Weather
A mainly fine day with the odd shower possible in the evening. Freezing level 2300m. Moderate southerly winds about the tops.
