Increased spring temperatures necessitate ongoing avalanche vigilance

As the weather begins to change and the days grow shorter, the mountainous regions of New Zealand's Southern Alps are gearing up for an increased risk of avalanches. Particularly around Aoraki/Mount Cook and the surrounding alpine zones, these areas, known for their higher snow accumulation and steeper slopes, are conducive to avalanches during seasonal weather changes.

Between November and April, a staggering 40% of avalanche fatalities in New Zealand have occurred, making it a crucial period for safety awareness. Ski touring remains very popular during this time, and with increased recreational activity above the bush line, such as alpine tramping, trail running, mountain biking, hunting, and ski touring, it's essential that everyone stays informed and takes necessary precautions.

The MetService meteorologist Luis Fernandes confirms that the weather in the spring remains turbulent, with heavy snow forecasted for the high alpine regions of the South Island on Friday. However, fine weather is expected over the weekend in these same regions.

The Mountain Safety Council (MSC) Chief Executive advises that the warming snowpack and more sunlight bring additional risks, but with proper management, it shouldn't prevent anyone from making it home safely. Regions won't close until the risk of avalanches has reduced further.

To help manage these risks, the public is encouraged to submit observations of avalanches and snowpack conditions at avalanche.net.nz. The avalanche advisory should be closely monitored for all regions, as forecasting is still underway. Spring is an active time for avalanches, which can occur at any time of the year when there is enough snow.

Aoraki/Mt Cook forecasting continues all year round, and a free online course is available to learn the basics or get a quick refresher on the essential components of travelling safely in avalanche terrain – skills, equipment, and forecast. More information about these components can be found here.

As the mountaineering season kicks off with key alpine regions like Aoraki/Mt Cook and Mt Aspiring seeing a huge boost in activity, it's important to remember that spring doesn't mark the end of the avalanche season. A small avalanche can be dangerous, even when the avalanche forecast is 'low' danger.
