Avalanche Problem
ウインドスラブ Wind slab
Be careful of extremely steep slopes on the ridge and just below the branch ridge.
概要
Avalanche
Yesterday, there was a report of a small loose snow avalanche observed on a steep southerly slope.
Snowpack
Strong westerly winds at higher elevations last night may have caused new wind slabs to form due to snow movement. The snowfall from the recent stormy weather is settling. On the steep southerly slopes, crusts have formed due to melting caused by solar radiation. The surface hoar observed in the Kagura area is buried about 10 cm below the surface, and in the Takezono area, a faceting layer is observed on the crust buried by the previous stormy weather, requiring caution for further bonding.
Weather
As of 5:00, there has been no snowfall at AMeDAS Fujiwara in the past 24 hours. The Japan Meteorological Agency is forecasting a gradually developing winter pressure pattern, but due to the influence of a pressure trough and moist air, it will be cloudy and sometimes sunny in the foothills of northern Gunma Prefecture, with some snow showers from midday.
