Travel and Terrain Advice
At higher elevations where it is snowing, watch for the formation of storm slabs. Even small avalanches can have serious consequences if there is a "terrain trap" lower down the slope. On the other hand, at lower elevations where rainfall continues, be on the lookout for glide avalanches. Stay away from steep slopes with glide cracks. Weather conditions are forecast to worsen distinctly, so plan your tour with this in mind.
Avalanche Problem
ストームスラブ Storm slab
Snow is falling at higher elevations and southwest winds (averaging about 10 m/s) are blowing. Watch out for increasing winds and snowfall in the future.
全層雪崩 Glide slab
Precipitation has been falling since yesterday. Stay away from slopes with glide cracks.
点発生湿雪雪崩 Wet Loose snow
On a very steep slope at an elevation that has rainfall.
持続型スラブ Persistent slab
It remains with high uncertainty.
概要
Avalanche
Yesterday (25th), a size 1 loose snow avalanche of size 1 wet avalanche caused by a ski cut was reported. Weather conditions were poor and no other avalanche reports have been received.
Snowpack
At lower elevations, rain has been falling since yesterday (the 25th) (about 10 mm by this morning). Since the temperature has started to drop since yesterday afternoon, snow has been falling at higher elevations. As the pressure pattern will shift to a winter type, please pay attention to the intensity of snowfall at higher elevations. In areas at lower elevations, even if temperatures drop slightly, the overall intensity of snowfall is still decreasing. Great care should be taken to avoid glide avalanches.
Weather
Today, a low pressure system with a front is expected to move eastward along the southern coast of Honshu while rapidly developing. The Japan Meteorological Agency is forecasting northeasterly and northerly winds, rain, and daytime high temperatures of 8 °C (13 m elevation) for the Joetsu region of Niigata Prefecture. At Sasagamine, Myoko (elevation 1,310 m), the temperature is 0 °C (as of 4:45 a.m.), and 4 cm of snow has fallen in the past 12 hours.
