午前中は快晴。午後は霧雨と気温低下に注意

The summit started with clear skies this morning, but visibility is currently below 1km, possibly due to a temporary fog. The temperature difference between the summit and base is 8.4℃, with a current wind chill of -2.3℃ at the summit. Temperatures will rise to 4.8℃ by noon, but conditions will deteriorate in the afternoon. Light clouds are expected from noon, and by 15:00, light drizzle is forecast with a high 78% chance of precipitation. Gusts up to 8.5m/s are anticipated, which, combined with moisture, will significantly lower the perceived temperature.

While there is no snow depth reported, shaded areas and depressions in Senjojiki Cirque may retain residual snow. The rising daytime temperatures will soften any remaining snow, and rocky sections around Hacchozaka and Mt. Hokendake will become wet. Steep slopes like Hacchozaka will be particularly slippery, requiring careful footing. Temperatures will drop to around 1℃ after 18:00, reaching -0.8℃ by 21:00, with light snowfall expected. This combination of moisture and freezing temperatures could lead to icy conditions overnight and into the next morning.

All activities should be concentrated in the early morning, with descent beginning no later than 14:00. Essential gear includes a base layer, a mid-layer such as fleece, and a waterproof/breathable outer shell, as wind chill will remain below freezing. Gloves and a hat are also crucial. Despite no current snow depth, carry microspikes or light crampons for residual snow and potential overnight ice. Although no significant alerts were detected by the automatic risk assessment, continuously monitor changes in visibility and temperature, and be prepared to turn back if conditions worsen.
