午後は霧雨と気温低下。穂先の岩場は滑りやすい

As of 7:30 AM, Mt. Yari summit is mostly clear but visibility is less than 1km. The base is clear. Summit temperature is 5.4℃, feeling like 3.1℃. Temperatures will rise to 7.9℃ during the morning, but light rain is expected by noon, intensifying to heavy drizzle by 3 PM. Temperatures are forecasted to drop to around 6℃ by evening.

The afternoon precipitation will make the chains and ladders on the Yariho peak wet and slippery. The risk of rockfall and slipping directly below the summit increases, requiring careful three-point contact and precise footwork. As indicated by the automated risk assessment, a sharp temperature drop of 6℃ is expected during the forecast period. Be prepared for sudden changes in conditions by carrying waterproof breathable rain gear, spare warm layers, and gloves. The perceived temperature will significantly drop when wet.

Make an early decision to turn back. Particularly after noon, the combination of drizzle and low temperatures increases the risk of hypothermia. While precipitation will cease at night, temperatures will drop to 1.5℃. Nighttime activity should be avoided.
