Travel and Terrain Advice
The spring cycle has begun. Avalanche danger levels vary widely from "low" to "high" during the course of a day, depending on the effects of daytime temperatures and solar radiation. We recommend taking action before the crust loosens up due to the effects of solar radiation and warmer temperatures. Watch for loose snow avalanches from large steep slopes with a southerly orientation. As the crust melts during the day, if your feet or skis sink deep or snowballs begin to roll, this is a sign of increased danger. At lower elevations, watch for open glide cracks and glide avalanches from cliff-like terrain with thin snowpack. Also be aware of possible collapses where snow cover is overhanging a large area. Do not enter the lower part of such slopes or pass through them quickly.

概要
Avalanche
Yesterday (14th), there was a report of a glide avalanche observed on an extremely steep slope at an elevation of around 1500m below treeline.
Snowpack
At higher elevations, the snow cover surface layer begins a cycle of melting during the day and freezing at night. At lower elevations, the intensity of the snow cover is weak due to the lack of nighttime cooling. No vulnerability has been observed in the middle to lower layers of the snowpack, but at lower elevations, the boundary between the snowpack and the ground is expected to be wet due to the effects of elevated temperatures.
Weather
As of 4:00 p.m., the temperature at AMeDAS Fujiwara is 0.4°C (32°F), with a weak nighttime chill, and the temperature at around 1300 m (-4.4°C). The Japan Meteorological Agency is forecasting clear skies, becoming cloudy before noon and gradually becoming rainy or snowy at night due to the influence of a high-pressure trough and moist air in the sky.
