Travel and Terrain Advice

This is a very dangerous condition. Today is another day where you should enjoy the slopes. Mountains are not only at risk of avalanches, but also of being incapacitated due to too deep snow. There is a possibility that deep snow that has not settling will not proceed even if the board is directed to the fall line. If you do that, you will be lured into a steep slope that is naturally dangerous. It's a situation where it's been suggested in advance that thoughts roll to the bad side. Please observe the open course inside the ski resort. It's for your safety, and it's also for the safety of other visitors. When sliding on non-pressure snow slopes and forests, let's act in multiple ways.

概要

Avalanche


Yesterday (31st), there were few visitors due to stormy weather, and there were no reports.

Snowpack


The stormy weather that continued from the day before yesterday (30th) brought a lot of snowfall. Even in the forest zone, it has exceeded 100cm. Snow accumulation caused by heavy snowfall with strong winds exhibits an unstable structure, contains multiple vulnerable layers within the snow layer, and conditions that can cause large-scale avalanches.

Weather


The Meteorological Agency predicts that the winter-type atmospheric pressure arrangement will gradually loosen for the northern part of Nagano prefecture, so it will snow widely in the north until the morning and gradually clear up in the afternoon. At AMeDAS Hakuba (elevation 703m), the temperature is -5.7℃ (as of 5:00).
