視界不良の山頂 冷たい風と濡れたザレ場に注意

Mount Meakan summit is cloudy with a perceived temperature of minus 5.8 degrees Celsius, indicating a significant chill. Visibility remains poor at less than 1 kilometer, with little improvement expected throughout the day. A temperature difference of approximately 5 degrees Celsius exists between the summit and the base, meaning colder conditions at higher elevations. Daytime temperatures will hover between 0 and 1.7 degrees Celsius, but high humidity will make wet scree slopes particularly slippery. Extra caution is required on the scree sections of the Onneto Course.

Wind speeds will slightly increase in the afternoon, with gusts exceeding 11 meters per second at times. The wind direction from the southeast to south-southeast could carry sulfur gas from the fumarole groups downwind. This, combined with poor visibility, increases the potential hazard. Be vigilant for sulfur gas inhalation and promptly move away if you detect any unusual odors or feel unwell.

Light rain is forecast from 6 PM, with temperatures dropping below freezing. Getting wet will further lower the perceived temperature, increasing the risk of hypothermia. Waterproof and breathable outer shells, quick-drying base layers, and insulating fleece or light down mid-layers are essential. Do not forget warm gloves and a hat. Concluding your activities well before sunset is advisable.
