台地は濃霧と霧雨。道迷いと低体温に警戒

Mount Naeba's summit is currently under thin clouds with dense fog, visibility less than 1 kilometer. The temperature is 8 degrees Celsius, feeling like 5.5 degrees, with 98 percent humidity. There's over a 7-degree difference from the base, making the summit feel quite chilly. Temperatures are expected to remain around 8 degrees throughout the day and into the afternoon, with light drizzle forecast from around 3 PM. Gusts of over 11 meters per second are anticipated.

The summit plateau is a vast wetland, and dense fog can easily lead to disorientation. Climbers on the Haraigawa or Koakazawa courses must be especially cautious of getting lost on the plateau. Since visibility will be severely limited, always carry a map and compass or a GPS device, and constantly confirm your position. Stepping off the boardwalks in the wetland is prohibited.

The ground will be wet and muddy due to high humidity and expected drizzle. Waterproof and cold-weather gear is essential. Wear a quick-drying base layer, a fleece mid-layer, and a waterproof-breathable shell jacket and pants. Gloves and a hat are also necessary. With perceived temperatures consistently around 5 degrees Celsius, there is a high risk of hypothermia. Stay dry and continuously replenish energy with snacks. Avoid pushing too hard, and be prepared to turn back if conditions worsen.

Light drizzle will cease by evening, transitioning to thin clouds and eventually mostly clear skies overnight, though temperatures will drop to around 7 degrees Celsius.
