Two skiers caught in an avalanche in Ohau

On July 5, an avalanche involving two people was reported in the Ohau hinterland of New Zealand.. Based on the limited information available, it appears that the avalanche occurred on a steep, wind-exposed slope subject to continuous wind loading. Of the three people, two were buried but survived because the avalanche occurred in open terrain, without cliffs or rocks.

The avalanche was reported as size 1.5 due to the risk of burial and injury. The avalanche was 20 centimetres deep and 10 metres wide on a 35° slope. It extended approximately 40 metres down the backcountry slope. The local Ohau Ski Patrol said the reactive avalanche hazard increased throughout the day and human-triggered avalanches were common on slopes adjacent to Ridge Crest. The overall avalanche hazard was low that day.

This is the first avalanche recorded for the 2024 ski season in New Zealand. It is recommended to check the New Zealand Avalanche Warning Bulletin for the most up-to-date forecast before heading out. It is also recommended to report any activity on their website under Public Observations. This will help with future forecasts.
