Travel and Terrain Advice
Act with caution for wet snow avalanches in elevation zones that may be affected by today's temperature increase and rainfall. Especially at lower elevations, watch for glide avalanches and wet snow avalanches, paying attention to the opening of glide cracks. In such areas, do not stay in place and move quickly through them. At higher elevations, be aware of the presence of localized wind slabs.
Avalanche Problem
点発生湿雪雪崩 Wet Loose snow
Announcement is current at this time. Increasing freezing level during the day, rainfall or snowfall, may also extend the treeline in all directions.
全層雪崩 Glide slab
The announcement is based on the current situation, but the forest treeline may also be extended in all directions depending on the increase in freezing level during the day and whether it rains or snows.

Beware of steep slopes with localized blowdowns, etc.
概要
Avalanche
Yesterday (10th), several naturally occurring point snow size 1 wet snowflakes were observed on the southerly slopes near 1400m, and many wet snow balls were observed in the lower elevation areas.
Snowpack
Slopes affected by yesterday's sunny skies and elevated temperatures (southerly slopes and all areas below 1000 m elevation) may be frozen this morning. Temperatures will rise during the day, and lower elevation areas may be affected by rainfall, so watch for glides in the snowpack and wet snow avalanches, including glide avalanches in all elevation zones. In higher elevation areas, there may be 20-30 cm of wind slab remaining locally on top of Melt-Freeze crust (March 5 rain).
Weather
As of 6:00, precipitation over the past 24 hours at AMeDAS Fujiwara was 0 mm. Temperature -3.4℃. The Japan Meteorological Agency is forecasting cloudy skies with some rain and snow showers before and after noon due to high pressure moving eastward and the influence of moist air.
