鎖場は湿潤 視界不良が続く 天狗岳への進路は慎重に

This morning, Ishizuchi-san summit is cloudy with a temperature of 7.8℃, feeling like 5.7℃. The base area near Tsuchigoya is at 11.7℃, indicating a 3.9℃ drop with elevation. Humidity is exceptionally high at 99%. Although no precipitation has been observed, rocks and chains are likely wet, creating slippery conditions. Particular caution is advised on the chain sections such as Ichino-kusari, Nino-kusari, and Sanno-kusari due to the wet surfaces, increasing the risk of slips. Considering bypass routes is a wise decision if conditions feel too risky.

The day is expected to transition to partly cloudy, with clearer skies possible by afternoon. Temperatures will rise to around 9℃ by noon, but high humidity will persist. Visibility is currently poor at 1.8km, requiring careful navigation on exposed peaks like Tengudake and Misen to avoid losing the route. While winds are forecast to diminish in the afternoon, gusts of 9-10 m/s are still possible, contributing to a lower perceived temperature.

With an effective temperature in the 5℃ range and high humidity, there is a risk of hypothermia from getting wet. A wicking base layer, a fleece mid-layer, and a windproof and waterproof outer shell are essential. Carry an insulating layer such as a light down jacket for breaks to prevent body heat loss. Full rain gear is necessary, and gloves will provide protection and warmth on wet chains. Although the risk of lightning is low, continuous vigilance for weather changes is crucial during your ascent.
