千畳敷カール 青空広がる。風は穏やか

Current conditions at Mt. Kisokoma summit are clear with visibility exceeding 20 kilometers. The temperature is 11.9 degrees Celsius, feeling like 10 degrees due to light winds. There is a significant temperature difference of 8.4 degrees Celsius compared to the base. The morning will remain clear, offering excellent conditions for ascents from Senjojiki Cirque up Hacchozaka, where trails are dry with exposed rock. Caution is advised for loose rocks.

For the afternoon, a 92% chance of precipitation is forecast by 3 PM, although no actual rainfall is expected. This suggests the potential for convective cloud development. While the risk of a full-blown thunderstorm is low, conditions can change rapidly in 3000-meter class mountains. Particularly when traversing exposed ridges like Mt. Hokendake, closely monitor cloud formations and consider an early turnaround. Gusts are predicted to reach up to 10.5 meters per second, which will significantly lower the perceived temperature on exposed ridges.

Layering is crucial. The perceived temperature will hover around 10 degrees Celsius in the morning and rise to about 15 degrees in the afternoon, but wind chill will make it feel colder. A base layer, a mid-layer such as a light fleece, and a windproof outer shell are essential. Carry a light down jacket for warmth during breaks or if temperatures drop. Rain gear is recommended as a precaution. Crampons or microspikes are not necessary.

Overall, conditions are suitable for climbing today. However, the elevated afternoon precipitation probability means the possibility of a sudden thunderstorm cannot be entirely ruled out. Therefore, an early start and descent are advised. If clouds begin to develop rapidly, prioritize immediate descent to ensure safety.
