Travel and Terrain Advice

At higher elevation zones, pay attention to the presence of new storm slabs. Beware of triggering on steep slopes, where the slope changes sharply. At low altitudes, be aware of the possibility of full-layer avalanches from open cracks and steep slopes. It is recommended not to enter the lower part of such places or to the bottom of the river, or to pass quickly. The boundary surface with the old snow in the lower elevation zone is expected to get wet and lose strength. Also watch out for point-generated wet snow avalanches on large steep slopes.

概要

Avalanche


Yesterday, there was a report that multiple naturally occurring point-occurring wet and wet avalanches of size 1-1.5 were observed on a steep southward slope.

Snowpack


At high altitudes, crusts are formed on the surface of the snow cover in all directions, and it is expected that 10-15 cm of snowfall from this stormy weather will be placed on it. The cold was weak and rainy in the low elevation zone. A large number of clyde cracks have been observed on the steep slopes towards the south.

Weather


The temperature at AMeDAS Fujiwara as of 4:00 is -0.1 degrees Celsius. There was snowfall of about 1 cm in the vicinity, and snowfall continues even now. According to the Meteorological Agency's announcement at 17:00 on the 19th, it will gradually be covered by high pressure, but it is expected to be affected by barometric valleys and moist air. For this reason, the northern part of Gunma prefecture is cloudy and sometimes sunny from early in the morning, and it is forecast that there will be places where it will snow until morning because it is affected by the chills in the sky.
