曇天から霧雨へ 鎖場は滑りやすく慎重に

Mount Ishizuchi starts with light cloudiness today, turning cloudy during the day with light drizzle expected around noon. The summit's felt temperature is forecast to be in the 8s Celsius in the morning, dropping to the 5s Celsius in the afternoon. There is nearly a 4-degree Celsius difference between the summit and the base, indicating a significant drop in perceived temperature with altitude gain.

Trail conditions will be wet to muddy due to the light drizzle. Specifically, the notorious chain sections such as Ichino-kusari, Nino-kusari, and Sanno-kusari will become slippery. Falls on these chains are a specific risk on Mount Ishizuchi, so consider using bypass routes and exercise extreme caution. Attention to footing is also crucial on the rocky ridges around Tengudake.

The combination of dropping felt temperatures and light drizzle increases the risk of hypothermia. A quick-drying base layer, a fleece mid-layer, and a waterproof-breathable outer shell are essential. Gloves are also mandatory for both safety on the wet chains and for warmth. While maximum gusts of 13.9 m/s are not strong enough to restrict movement, be mindful of body temperature drops on exposed ridges.

The risk of lightning is low, but be aware of the afternoon weather deterioration. Current visibility is excellent at over 16km, but it may temporarily worsen with the drizzle. Temperatures will further drop to the 6s Celsius in the evening and overnight, so even for day trips, severe cold weather gear is necessary for any potential night activity.
