視界不良の霧が支配。足元は滑りやすく雨具は必須

Current conditions at the summit of Kuju Mountains are cloudy with a temperature of 11.4°C, feeling like 9.7°C. Humidity is 99% with visibility limited to 1.4km, indicating dense fog. The base at Makinoto Pass is 16.1°C, a noticeable 4.7°C warmer than the summit. Cloudy weather is expected throughout the day, with temperatures rising to around 12°C, but the felt temperature will remain around 10°C. The probability of precipitation is high, reaching over 90% in the afternoon, meaning rain could begin at any time.

The ground is consistently wet due to high humidity, and the volcanic soil, when wet, becomes slippery. Particular caution is advised on the ridgelines, especially on the Makinoto Pass course towards Mount Nakadake and Mount Kuju, where poor visibility combined with slippery terrain heightens the risk. The specific risk of getting lost in the fog, common in the Kuju Mountains, is high today. Constant vigilance with map, compass, and GPS is essential for careful route finding. Full rain gear, including jacket and pants, is mandatory. A fleece mid-layer for warmth and a quick-drying base layer should also be carried.

Winds will be from the southeast throughout the day, with speeds around 4m/s and gusts up to 9m/s, not reaching strong wind levels. However, the combination of high humidity, felt temperatures around 10°C, perspiration, and exposure to wind increases the risk of hypothermia. Managing perspiration during activity and maintaining warmth during breaks are crucial. While no thunderstorms are forecasted, the high chance of precipitation necessitates preparedness for sudden weather changes. Winds are expected to calm down and precipitation probability decrease in the evening, but limited visibility may persist.
