霧雨続き視界不良。濡れた足元と突風に警戒

Mount Miyanoura summit experiences heavy drizzle and visibility below 1 kilometer. The current feels-like temperature is 14.7 degrees Celsius, but persistent drizzle, winds around 4 meters per second, and gusts exceeding 22 meters per second are expected throughout the day. With humidity near 100 percent, you will be constantly wet, making the actual felt temperature even lower. Layering should include a quick-drying synthetic base, a light fleece mid-layer, and a waterproof-breathable rain jacket and pants. Carry extra insulation like a thin down jacket or fleece.

The ground will remain muddy due to continuous precipitation and high humidity. Be extremely cautious of rapidly swelling streams. Mount Miyanoura is known as an exceptionally rainy area, and prolonged rainfall can cause sudden increases in water levels at river crossings and stream beds along routes like the Yodogawa Trailhead. Absolutely avoid attempting dangerous river crossings. Pay attention to slippery rocks and tree roots.

Poor visibility will persist all day, significantly increasing the risk of getting lost in open areas such as the Hananoegawa Wetlands. Constantly check your compass, map, and GPS, paying close attention to staying on the designated route. Gusts are strong enough to knock you off balance, making exposed ridges and open areas hazardous. Hypothermia risk is high due to constant wetness; take frequent breaks and consume warm food and drinks to maintain body temperature. This is a long-distance route that is difficult to complete in a single day, and reckless actions can lead to accidents.

Drizzle will continue into the night, keeping conditions wet. No significant improvement in weather is expected until early tomorrow morning. If camping, ensure thorough waterproofing and insulation inside your tent.
