Travel and Terrain Advice
At lower elevations, the snow surface layer has lost strength due to rainfall. Wet snow avalanches are very heavy, and small ones require caution. Even in forested areas, loose snow avalanches can still occur, so use caution. Also, stay away from slopes that already have glide cracks in them, as they are very dangerous.

概要
Avalanche
No new avalanches were reported yesterday (February 18).
Snowpack
Weak rainfall began yesterday afternoon (February 18) and has been in full swing since early today. As a result, the snow in the below treeline is sufficiently wet. A cold front is expected to pass overhead, shifting to a winter pressure pattern and lowering temperatures.
Weather
The Japan Meteorological Agency is forecasting winds from the north, winds from the south during the day, rain, cloudy from midday, partly cloudy at night, snow, and a maximum temperature of 11°C (418 m elevation) for northern Nagano Prefecture. At AMeDAS Hakuba (elevation 703 m), the temperature is 1.3°C (as of 5:00 pm) and 37 mm of rain has fallen in the past 12 hours.
