午前中の岩稜帯は好機 午後霧雨で滑落注意

Mount Tsurugi summit experiences a clear and calm morning with visibility exceeding 20km and near-zero wind. The temperature is 11.8℃, feeling like 10.8℃, offering comfortable conditions for activity. There is approximately a 6℃ temperature difference from the base. Utilize this morning's favorable weather to traverse critical rocky sections like Kani-no-Tatebai and Kani-no-Yokobai early. Currently, the exposed rock ridges are dry, but light drizzle is expected to begin around 12:00, with precipitation probability rising to 59% by 15:00. Wet rock faces become slippery, increasing the risk of falls and rockfall, particularly on the chains of Betsuzan-one and narrow ridges. A helmet is mandatory.

A significant temperature drop of up to 6℃ is forecast during the period. Temperatures will fall below 10℃ by evening, reaching 7.4℃ by early tomorrow morning. To prepare for sudden changes in perceived temperature, always carry a base layer, a mid-layer like fleece, and a waterproof-breathable outer shell. Wear them during breaks or in adverse weather to prevent hypothermia.

The current mild conditions will shift in the afternoon. The maximum gust is 4.6m/s, so strong wind risk is low. No lightning is forecast. However, wet rock surfaces and decreasing temperatures pose the primary hazards, so make early decisions to turn back and avoid pushing limits.
