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 daytime temperatures and the effects of solar radiation. We recommend that you take action before the crust loosens up due to the effects of solar radiation and warmer temperatures. When the crust melts and your feet or skis sink deep or snowballs begin to roll, this is an indication that the danger level is increasing. Watch for loose snow avalanches from large steep slopes and glide avalanches from glide cracks or cliff-like slopes. Do not enter the lower part of such areas or pass through them quickly.
Avalanche Problem

Watch out for open cracks and cliff-like terrain.
点発生湿雪雪崩 Wet Loose snow
Beware of large steep slopes with more snow to get caught in.
概要
Avalanche
Yesterday, there were reports of multiple glide avalanches (size 1) and loose snow avalanches (size 1) on extremely steep southerly slopes.
Snowpack
At least in all directions below 1600 m, the snow surface is in a cycle of melting and then freezing at night to form crusts, but at lower elevations, the strength of the snowpack is weak due to strong Melt-Freeze. Weakness is not observed from the middle to the lower layers of the snowpack.
Weather
As of 5:00, the temperature at AMeDAS Fujiwara is -0.7°C. At around 1300 m elevation, the temperature is 3.9°C. There is no cooling during the night. The Japan Meteorological Agency is forecasting cloudy skies and rain around the beginning of the night with some thunderstorms in the evening due to the expected influence of moist air and cold air above, and daytime temperatures in Minakami Town will rise to 14°C (57°F).
