宮之浦岳 視界回復も足元は湿潤 沢の増水警戒

Mount Miyanoura summit is currently cloudy with visibility less than 1 kilometer, indicating dense fog. The temperature is 12.1 degrees Celsius, with gusts reaching 14.7 meters per second. The Yodogawa Trailhead area at the base reports partly cloudy skies and 16.5 degrees Celsius, a notable 4.4-degree difference from the summit. While dense fog persists this morning, it is forecast to clear to partly cloudy by noon and completely clear by 3 PM. Winds are also expected to gradually weaken throughout the afternoon.

Ground conditions are anticipated to be wet to muddy due to high humidity and the mountain's characteristic as a heavy rainfall area. Although no precipitation is currently forecast, Mount Miyanoura is known for its exceptionally high annual rainfall, posing a constant risk of rapid river swelling. Particular caution is advised for navigation in dense fog, especially in flat areas such as Hananoego Marsh. Wear waterproof hiking boots and ensure secure footing during your ascent.

The current feels like temperature is 11 degrees Celsius. While the daytime high is expected to reach 15 degrees Celsius, the 99% humidity and wind maintain a risk of hypothermia from sweat or wetness. Wear a moisture-wicking base layer, an insulating mid-layer like fleece, and a waterproof-breathable outer shell. Adjust layers frequently to regulate body temperature. While the risk of lightning is low, be mindful of strong gusts that could affect balance.

Clear skies and calm winds are expected from evening into the night. Temperatures will drop to 11.8 degrees Celsius overnight, necessitating adequate insulation during stops. Partly cloudy conditions are forecast for early tomorrow morning, but no precipitation is expected.
