午後霧雨の予報。防水対策を徹底せよ

The summit will experience cloudy conditions throughout the morning, with temperatures rising from the low 13s to the upper 18s by afternoon. Winds will remain light, making the felt temperature similar to the actual air temperature. However, light drizzle is forecast to begin around noon and continue until approximately 3 PM. During this period, visibility will degrade, and ground conditions will become wet and muddy.

Particular caution is advised on shaded routes such as the forest tree runs, where muddy ground and slippery obstacles may be present. The temperature difference between the summit and base is about 4°C, so it may feel cooler at higher elevations. Essential layering includes a wicking base layer, a light fleece or long-sleeve shirt as a mid-layer, and a waterproof-breathable rain jacket and pants as an outer layer. To prevent hypothermia from getting wet, wear your outer shell during breaks or when stationary, and be mindful of sweat cooling.

The rain is expected to clear by evening, with forecasts showing mostly clear skies around 9 PM, though temperatures will drop to the low 12s. Consider bringing additional warm layers if your activity extends into the evening. While no significant alerts were detected by the automated risk assessment, always remain vigilant for sudden weather changes and fluctuating visibility, and be prepared to turn back if conditions deteriorate.
