山頂は低温と雨。濡れによる低体温症に警戒

Current conditions at Sapporo Kokusai Ski Resort summit show cloudy skies with a temperature of 4.6 degrees Celsius, feeling like 0.6 degrees Celsius. The base area at 625m is 7.6 degrees Celsius, a 3-degree difference from the summit. Be mindful of this temperature variation due to elevation during your day's activity.
Light rain is expected to begin around noon, with temperatures dropping to 4.7 degrees Celsius. Winds are forecast at 3.92 m/s with gusts up to 13.8 m/s. Getting wet in these conditions will significantly lower your perceived temperature, increasing the risk of hypothermia. When traversing the longest 3,600m course, even if you warm up in the initial stages, you could feel chilled later on, making frequent layering adjustments crucial.
With no snow cover and light rain expected, the ground will be generally wet to muddy. Footing may be slippery, especially in poorly drained areas. Essential gear includes a moisture-wicking base layer, a mid-layer like fleece, and full waterproof breathable rainwear. Waterproof gloves and a knit cap are also recommended.
Rain is expected to cease by evening, and temperatures will slightly recover, but remain cool. Always pay close attention to your physical condition and weather changes, and avoid any unnecessary risks.
