午後から霧雨と風。体感低下に備えよ

As of 7 AM, the summit is cloudy with a temperature of 14.1°C, feeling like 12.6°C. A 3°C temperature difference from the base is already observed, highlighting Sapporo Kokusai Ski Resort's characteristic "significant weather differences between the summit and base." The morning will be relatively calm with dry ground conditions. However, light drizzle is expected to begin around noon, with precipitation probability rising to 71% in the afternoon. Winds will shift from southwesterly to westerly, with gusts reaching 12 m/s. The combination of wetness and wind will significantly lower the felt temperature.

As indicated by the automated risk assessment, a sharp temperature drop of 7°C is anticipated during the forecast period. If your body gets wet from the afternoon drizzle, this temperature drop substantially increases the risk of hypothermia. Waterproof and breathable outer shells are essential gear, and carrying an extra mid-layer such as a fleece is advised. Wear these layers proactively to prevent getting wet and cold.

While the ground is dry in the morning, it will become wet from the afternoon drizzle, leading to muddy sections on hiking trails. Caution against slips and falls is necessary. With no snow accumulation, crampons or microspikes are not needed. The risk of lightning is low, but be alert to reduced visibility due to strong winds and drizzle, especially on ridge lines. We strongly recommend an early start and an early finish to avoid the deteriorating afternoon weather.
