雨と濃霧が視界を奪う。濡れた岩稜に足元注意

Current conditions at Mount Miyanoura summit are cloudy with a temperature of 12.4°C, a feels like temperature of 11.1°C, and 99% humidity. Visibility is already limited at 2.3km. There is a 3.4°C temperature difference from the base, indicating colder conditions at higher elevations. Light drizzle is expected to begin around 9 AM, turning into light rain by noon, and then heavy rain in the afternoon. The probability of precipitation is 100% throughout the afternoon, with over 15mm of total rainfall anticipated. Gusts will reach 14 to 16 m/s during the day, posing a risk of losing balance on exposed ridges.

Ground conditions will be wet and muddy due to the persistent rain and high humidity. Wooden boardwalks and rocky areas, especially around Hananoego Marsh, will be slippery. As Mount Miyanoura is an exceptionally rainy region, continuous rain increases the risk of rapid swelling of streams. When approaching from the Yodogawa Trailhead, exercise extreme caution at stream crossings and along riverside routes. Visibility is unlikely to improve all day, making the risk of getting lost in dense fog very high. Frequently check your GPS and map to avoid losing the route.

The feels like temperature will drop further due to rain and wind. Wear a quick-drying base layer, a fleece mid-layer, and a waterproof-breathable rain jacket as an outer layer. Always carry extra insulation for breaks or emergencies. Crampons or microspikes are not needed, but hiking boots with good grip for slippery terrain are essential. The risk of hypothermia due to strong winds and rain is very high; consider turning back if conditions worsen. Rain will continue overnight with temperatures around 11°C, increasing the risks of poor visibility and hypothermia for any night travel, which should be avoided.
