霧雨が続き体感冷える。滑りやすい足元に注意

Sapporo Kokusai Ski Resort expects persistent drizzle to light rain throughout the day. At the summit, the current perceived temperature is a chilly 3.6 degrees Celsius, and it is forecast to remain around 3 degrees Celsius during the day. Wind speeds will be 4 to 5 meters per second, with gusts potentially reaching close to 15 meters per second at times. Exposed to wind and rain, the body can rapidly lose heat, increasing the risk of hypothermia. There is currently a 3-degree Celsius temperature difference between the summit and the base. Those traversing the longest 3,600-meter run should be particularly mindful of these temperature and weather changes, as well as the wind chill effect.

Ground conditions will remain wet all day, and with continued precipitation, many sections are likely to become muddy. There is no snow cover, so crampons or microspikes are not necessary. However, waterproof trekking shoes are essential to navigate the slippery and muddy terrain. For layering, wear a quick-drying base layer, a light fleece or wool sweater as a mid-layer, and a waterproof and breathable rain suit (jacket and pants) as an outer layer. Gloves and a hat are also crucial for maintaining body temperature.

Visibility is currently 3.5 kilometers but may decrease further due to the drizzle and fog. Be especially vigilant about confirming your current location and route, particularly near the summit where dense fog can severely obscure vision. While the risk of lightning is low, severe caution against hypothermia is paramount. If you feel cold or wet, it is vital to make the decision to turn back without hesitation. The rain is expected to continue into the night, with temperatures dropping further. All outdoor activities should conclude during daylight hours.
