Travel and Terrain Advice
In the Alpine, the hard melt-freeze crust or Ice surface is exposed and care should be taken to avoid slipping and falling. Very hard debris from the wet avalanche that occurred during the rainfall on January 14 has accumulated on the gully bottom, hindering skiing. Below Treeline, there are many holes in the gully and a lot of bushes. The little snow does not fill out the complex terrain. If you are relying on GPS route data from the previous season, It would result in a loss of the way. Please check terrain maps and recognize with your own eyes the actual mountain conditions in front of you. Although the avalanche danger level is low, the conditions require experience and skill to act in the mountains.
Avalanche Problem
点発生湿雪雪崩 Wet Loose snow
Very steep slope with the strong influence of daytime sunny slope and elevated temperatures
概要
Avalanche
No new avalanches were observed in mountain areas yesterday (January 19).
Snowpack
The effects of last weekend's rainfall have reached the alpine area, and the snow surface is hard frozen with subsequent snow on top of it. After the snowfall, very strong winds blew, exposing icy old snow surfaces in areas exposed to the wind. Weak snowfall over the past few days has also eliminated the instability.
Weather
The Japan Meteorological Agency is forecasting winds from the south, then from the west, clear, then cloudy, snow or rain in the evening, and a high of 12°C (13 m elevation) for the Joetsu region of Niigata Prefecture. At Sasagamine, Myoko (elevation 1,310 m), the temperature is -8° (as of 4:45 a.m.).
