稜線は冷たい霧雨。視界保たれるが低体温症に警戒

The summit area of Kuju Mountains is cloudy with a temperature of 9.8℃, feeling like 7.9℃. There's about a 5℃ temperature difference from the base, indicating cold air dominates the ridges. While it will be partly cloudy until noon, light drizzle is expected to begin after 12:00, with a 65% chance of 0.2mm light rain by 15:00. The perceived temperature during this time will drop to around 7℃, potentially falling to 5℃ with gusts.

The ground will be wet to muddy due to the light drizzle and 96% humidity. Waterproof hiking boots and gaiters are essential, especially on popular routes like the Makinoto Pass course and around Bogatsuru Marsh, where conditions can be slippery. Furthermore, the persistent drizzle increases the risk of poor visibility, which is a specific hazard of the Kuju Mountains leading to getting lost in the fog. On wide ridges like those of Mt. Mimata and Mt. Ofune, frequently check your GPS and map to confirm your current location.

Winds will be around 4m/s throughout the day, but gusts exceeding 11m/s are possible in the afternoon. Exposed ridges are susceptible to wind, and strong winds combined with wet conditions can lead to a rapid drop in body temperature. Always carry quick-drying base layers, a fleece mid-layer, and waterproof breathable rainwear. During breaks, use a lightweight down jacket for insulation. Adjust layers frequently while moving to regulate body temperature. While the risk of lightning is low, drizzle and cloud cover will continue after sunset with temperatures around 8℃, so avoid unnecessary nighttime activities.
