Travel and Terrain Advice
Watch for bonding of wind slabs on steep slopes just below high elevation ridges and branch ridges where bonding is difficult to proceed, and for collapsing snow cover. Daytime temperatures are expected to rise and solar radiation will be strong. Also watch out for the possibility of wet snow avalanche from large southerly steep slopes.

概要
Avalanche
Yesterday (18th), there were no reports of new avalanches, but there were reports of small snow slabs collapsing; on the 17th, there were reports of multiple wind slabs (size 1) observed near 1400m in the Tanigawadake area due to human-triggered avalanches.
Snowpack
Strong westerly winds through the morning of the 18th formed wind slabs on the downwind slopes. A low-density snowpack was reported on the boundary of a crust that formed on the south slope at a lower elevation and was buried on the 15th, but bonding is unknown. The middle part of the snowpack has been settling and bonding.
Weather
As of 6:00, the temperature at AMeDAS Fujiwara is -8.3℃. There has been no new snowfall and settling is progressing. The Japan Meteorological Agency is forecasting clear skies and cloudy mornings and evenings as high pressure builds over the area, but a low pressure system will develop off the Tokaido coast and pass near the Izu Islands in the evening.
