Travel and Terrain Advice
Except at higher elevations, the mountains are quickly taking on the appearance of spring. In the Alpine, you need to be aware of wind slabs that remain in isolated terrain features. On lower elevation and sunny slopes, be on the lookout for wet loose snow avalanches and glide avalanches. Wet snow is very heavy and easily scoots underfoot. High temperatures are forecast again today, so please stay away from slopes that already have glide cracks. Have a good day.

概要
Avalanche
Yesterday (February 11), whumpfing sounds were reported on the southeast slope of the Treeline. In addition, some wet loose snow avalanches were reported on a slope at a lower elevation and under the influence of strong sunny slopes.
Snowpack
Yesterday, high temperatures and strong solar radiation caused the stormy snow to settle quickly, wetting the sunny slopes and forming crusts in all directions at the lower elevations.
Weather
The Japan Meteorological Agency (JMA) is forecasting a southerly wind, clear skies, cloudy from midday, and a high of 10°C (13 m above sea level) for the Joetsu region of Niigata Prefecture. At Myoko Sasagamine (elevation 1,310 m), the temperature is -1° (as of 5:45 a.m.).
