Beware of steep slopes
概要
Avalanche
Yesterday (3rd), there was a report of a naturally occurring loose snow avalanche (size 1) and a wind slab avalanche (size 1.5) observed on an extremely steep southerly slope.
Snowpack
Snowfall with low density and large grain size has been observed on the snow cover surface, and attention should be paid to bonding with the snowfall of this stormy weather. Yesterday's sunny slopes are expected to melt the snow surface and form crusts on the southerly slopes.
Weather
As of 4:00, the temperature at AMeDAS Fujiwara is -1.8°C. Around the area, about 2 cm of snow has fallen in the past 12 hours, and light snow is still falling. The Japan Meteorological Agency is forecasting cloudy and sometimes snowy conditions in the foothills of northern Gunma Prefecture due to a strong winter pressure pattern and the influence of a pressure trough and cold air.
