Travel and Terrain Advice
Overall conditions are improving, but the higher the elevation, the stronger the influence of the wind, and care should be taken to avoid the formation of wind slabs. In addition, instability within the recent snowfall has not been completely eliminated, so observe the terrain carefully and choose simple slopes without "terrain traps". On steep south-facing slopes at lower elevations, where the effects of solar radiation and rising temperatures are stronger, watch for snow changes during the day. If snowballs due to wet snow begin to form, this is a sign of danger. Keep an eye on slopes above you. This is a great day for great weather. Bring sunscreen and plenty of water. Have a great day.

概要
Avalanche
No new avalanches were reported yesterday (12th). Several wind slab avalanches were reported in the alpine area of the adjacent Hakuba mountain range.
Snowpack
New snow from snowfall over the past few days has been reported to be sintering and settling. Despite limited observations, no major problems have been found with the bonding of the new snow with the old snow. Although there is a lack of information on alpine areas, the situation in the nearby Hakuba area warns against wind slab.
Weather
The Japan Meteorological Agency is forecasting a southerly wind, daytime, westerly winds, clear skies, and a daytime high of 12 °C (13 m elevation) for the Joetsu region of Niigata Prefecture. At Sasagamine, Myoko (elevation 1,310 m), the temperature is -3 °C (as of 4:45 a.m.), with no new snowfall in the past 12 hours.
