Travel and Terrain Advice
This is a "spring day" with snowpack intensity decreasing during the day. However, today is a day of a struggle between these two forces: a cold north wind that takes heat away from the snow surface, and a decrease in snow cover intensity due to rising temperatures and solar radiation. Please monitor the changes in the strength of the snowpack surface layer carefully. Snow is melting at lower elevations, and areas that were passable in February may have broken up or the ground is exposed. In such places, it is easy to relax with upward caution. Watch out for glide avalanches and snow block collapses.

概要
Avalanche
Yesterday (March 13), few people entered the mountain and no avalanche bulletin was received.
Snowpack
Yesterday morning (March 13), rain fell at the foot of the mountain and snow fell at higher elevations. Based on the amount of precipitation, there was about 10-15 cm of new snow at the Treeline. Please check the bonding of new snow and old snow. A northerly wind is forecasted to blow in today, and temperatures are not expected to rise much. However, once the sunny slopes begin to penetrate the southern slopes, the intensity of the snow cover is expected to rapidly decrease.
Weather
The Japan Meteorological Agency is forecasting southerly winds, northerly winds during the day, cloudy, sunny before noon, and a maximum temperature of 11°C (13 m above sea level) for the Joetsu region of Niigata Prefecture. At Sasagamine, Myoko (elevation 1,310 m), the temperature is -5° (as of 5:45 a.m.).
