槍ヶ岳 穂先ガス中。午後から視界回復へ

As of 7:30 AM, Jagged Peak summit is thinly clouded with a temperature of 2.2℃ and a wind chill of -0.4℃. Visibility is less than 1km, making the exposed rock sections, particularly the Jagged Peak's chains and ladders, challenging to navigate. The risk of rockfall and slipping is elevated under these conditions. It is advisable to delay summit attempts until visibility improves in the afternoon.

Winds remain light throughout the day, with gusts peaking at 6.9 m/s, not significantly impeding movement. However, on the exposed ridges above the tree line, the combination of low ambient temperature and 96% humidity can quickly lead to hypothermia. Essential layering includes a base layer, a mid-layer like fleece, and a windproof/waterproof outer shell. Gloves and a warm hat are crucial for extremity protection.

No precipitation is forecast, meaning ground conditions are primarily exposed rock, though high humidity may result in damp surfaces. Crampons or microspikes are not necessary. While thunderstorms are not explicitly predicted, rapid weather changes are common in summer mountains. Remain vigilant for any signs of lightning and descend immediately if thunder is heard.

Conditions are expected to improve in the afternoon, with mostly clear skies and temperatures rising to 6.1℃ by 3 PM. However, temperatures will drop sharply after sunset, reaching -0.6℃ by midnight. Night travel is not recommended due to the severe cold.
