稜線は濃霧に注意。行動は慎重に

Mount Hakusan summit is mostly clear, but visibility remains below 1km, indicating dense fog. The current summit temperature is 5.3℃, feeling like 2.5℃. A significant temperature difference of over 10℃ exists between the summit and the base, making it feel considerably colder at higher elevations. Temperatures will gradually rise during the day, reaching 8.1℃ by noon and 8.3℃ by 3 PM. However, skies will become partly cloudy, and precipitation probability will increase in the afternoon. Although no actual precipitation is forecast, this suggests a potential for deteriorating weather.

Ground conditions are primarily exposed rock and dry to slightly damp soil, with zero snow depth. While the risk of snowfield slips typical in the late snow season is low, some isolated patches of damp snow or frost might persist in shaded or hollow areas. Crampons or microspikes are not necessary. However, carrying a waterproof and breathable outer layer is essential for wind and cold protection.

A critical concern is the "dense fog on ridges," a characteristic risk of Mount Hakusan. The current poor visibility significantly increases the risk of disorientation when approaching peaks like Gozen-mine and O'nanjimine. Gusts up to 10.2m/s are not severe enough to impede movement, but combined with the dense fog, they can further lower the perceived temperature, increasing the risk of hypothermia. Exercise extreme caution on ridges to prevent getting lost.

The increasing precipitation probability in the afternoon also hints at potential thunderstorms. While no direct lightning forecast is issued, always be vigilant for sudden weather changes. Given the consistently low perceived temperatures throughout the day, layered clothing, including a base layer, a fleece mid-layer, and a windproof/waterproof outer shell, is crucial for maintaining warmth.
