Backcountry adventurers warned about avalanche threat

The Southern Alps of New Zealand have been heavily blanketed with snow recently, setting the stage for an exciting winter ahead. However, the early season snowfall has also brought about some challenges, particularly in terms of avalanche safety.

The New Zealand Avalanche Advisory (NZAA), owned by MSC, has commenced forecasting earlier this season due to the current weather systems. This early start is crucial as ski areas are not yet fully operational, leading to a lack of conditions data for avalanche forecasters.

Several regions, including Arthur's Pass, Craigieburn Range, Aoraki/Mt Cook, the new Aspiring region, and Tongariro in the North Island, have been classified as 'high' avalanche danger by the NZAA. This level indicates very dangerous avalanche conditions where travel is not recommended.

The new Aspiring forecast region is available at avalanche.net.nz. In addition, the Mt Aspiring National Park, Mt Brewster, the Treble Cone backcountry, and Main Divide areas now have more tailored avalanche forecasting.

The snowfall is predicted to be quite variable across the regions. More snow is forecasted over the coming week, even as far North as Tongariro National Park. This variability, combined with the early season conditions, necessitates conservative decision-making.

In the southern part of New Zealand, particularly on the South Island, natural and human-triggered avalanches are likely in high danger zones, according to the NZAA. The grace period for fresh snow to settle can sometimes be multiple days, adding an extra layer of uncertainty for a few weeks.

Despite these challenges, the early snowfall should set up for a great season ahead by setting an excellent base. However, it's important to pick the right moment to step out for the first time to ensure safety.

Help for rescue operations would be further away as ski areas aren't yet open for the season. Therefore, checking the latest avalanche advisory will help determine safe regions and better conditions once things settle.

In conclusion, the early snowfall in New Zealand's alpine regions has brought about unique challenges in terms of avalanche safety. However, with the early start of the NZAA's forecasting and the public's vigilance, the winter season is expected to be a safe and enjoyable one.
