霧雨の岩稜。文三郎尾根は足元注意

Today on Akatake, persistent drizzle will keep the mountain ridges wet throughout the day. The summit currently registers 7.3 degrees Celsius with a feels-like temperature of 5.8 degrees Celsius. The high humidity of 98% combined with continuous precipitation significantly increases the risk of hypothermia, as body heat is rapidly lost when wet. The wet rock sections pose a high risk of slipping and falling. Extreme caution is required, particularly on the chains and ladders of the Bunzaburo-one and Jizo-one routes.

There is an 8.7-degree Celsius temperature difference between the summit and the base, meaning that while the base may feel mild at 16 degrees Celsius, the summit conditions are cold. Essential gear includes a quick-drying base layer, a mid-layer such as fleece or light insulation, and a waterproof-breathable rain suit for your outer layer. Waterproof gloves and a hat are also crucial to prevent heat loss from exposed skin.

Current visibility is 2.9 kilometers, but persistent drizzle may lead to dense fog, further reducing visibility. Route loss due to thick fog is a specific risk in the Yatsugatake area, so continuously verify your position using a map, compass, and GPS. Precipitation is expected to continue through the afternoon, gradually weakening from evening into night, with a forecast of mostly clear skies by 3 AM tomorrow.
