Travel and Terrain Advice
Avalanche danger is high in the northern part of the Myoko Mountains. Even if you are in the forest, consider whether there is a large start zone above you. In the event of heavy snowfall, avalanches can occur even in the forest if the slope is steep enough. Even if the size is small, snow is heavy, and if it hits a tree, the consequences can be serious. In addition, snowfall in a short period of time hides terrain traps. Try to think about what is hiding under the new snow.
Avalanche Problem
概要
Avalanche
Yesterday (January 2), a size 1 avalanche was reported at the ski resort safety management. No information has been received at higher elevations.
Snowpack
Snowfall is heavy on the northern side of the Myoko Mountains, with 60-80 cm of new snow below treeline. The mountain range is receiving westerly winds, which are creating wind slabs at higher elevations. Below treeline, where there is no wind influence, the snow is soft and new snow is settling well.
Weather
The Japan Meteorological Agency is forecasting westerly winds, snow, and a maximum temperature of 4°C (13 m elevation) for the Joetsu region of Niigata Prefecture. At Sasagamine, Myoko (elevation 1,310 m), the temperature is -7°C (as of 4:45 a.m.), with no new snowfall in the past 24 hours.
