霧雨に濡れる山肌。視界不良に注意

As of 7 AM, the summit of Sapporo Kokusai Ski Resort is cloudy with a temperature of 6.5°C, feeling like 4.2°C. Visibility is less than 1km, enveloped in fog. There is a significant 3°C difference from the base, indicating a notable temperature drop at the summit. Light rain or drizzle is expected to continue throughout the day, with precipitation temporarily intensifying in the afternoon. Temperatures will remain around 6°C, but with 99% humidity and wind gusts reaching up to 15m/s at times. Getting wet will further lower the perceived temperature, necessitating strict vigilance against hypothermia.

With no snow cover, the ground will be wet to muddy all day. Exercise extreme caution against slipping on wet rocks and soil. The "visibility reduction due to fog at the summit" specifically makes route finding difficult, so avoid any ambitious activities. Despite the easy access from Sapporo within an hour, do not be complacent and prepare thoroughly.

For your activity, always wear a quick-drying base layer, a mid-layer such as fleece, and waterproof-breathable rainwear (jacket and pants). Waterproof gloves and a hat are also essential. Although no significant alerts were detected by the automated risk assessment, risks of poor visibility, wet surfaces, and hypothermia are ever-present. Pay close attention to weather changes, and if you feel any discomfort, it is crucial to make a prompt decision to turn back.

Light rain will persist into the night, with temperatures dropping to around 3°C. Continuously monitor the conditions throughout the day and act within your limits.
