2025.02.13 Thursday

Mountain base -7℃, 10cm humid snowfall in 12h. Moiwa 800m: -7.9℃, NNW11.9m/s, snowdrifts developed. Annupuri 1100m: -9.8℃, NW7.5m/s, strong snowfall. Hirafu Hanazono: -8.9℃, NNE4.2m/s, heavy snowfall. Coastal data: Benkei cape NNW11m/s, Kamui cape N11m/s, 997hPa, 0.8m waves. 

The low-pressure system moved east and a wintery pressure distribution is back in place. Wind and snow beyond 15m/s is blowing in high altitude, making cornice and windload slabs develop. Snowdrifts will grow throughout the day and the avalanche risk in slopes above 800m elevation will rise dramatically. All peak gates will be closed for safety measures. Ropes must not be crossed. Please understand that a single track under the rope will lead many others to follow, and eventually end up in an accident. Please be responsible and follow the ski resort’s rules. The weather conditions are completely different at the base and at the peak. Today’s a day to be extra careful. Visibility is bad, beware of trees. The snow’s a little heavy, but pretty good in the treeruns. Overconfidence and ignorance are the two key elements that cause accidents. Winter sports are not safe activities. Have a nice day.
