霧雨と視界不良の鳥海山。足元と滑落に注意

Mount Chokai summit currently experiences light rain and mist, with visibility at 5.5km. The feels-like temperature is a chilly 9.4℃. In contrast, the foothills are experiencing heavy mist and rain but at a warmer 24.3℃, indicating a significant temperature gradient. Light rain and mist are expected to continue intermittently throughout the day, with temperatures hovering around 10℃. Gusts up to 11m/s are forecasted for the daytime, which, combined with mist from the Sea of Japan, could lead to prolonged poor visibility.

Trail conditions are generally wet to muddy. Particular caution is advised around the rock formations near Shinzan, where wet surfaces increase the risk of slipping and rockfall. Thorough route selection and maintaining three points of contact are crucial in these areas. Full rain gear, both jacket and pants, is essential, and staying dry should be the top priority during your ascent and descent.

Given the low feels-like temperature, the risk of hypothermia increases significantly if you get wet. Proper layering is critical: a wicking base layer, a mid-layer such as fleece, and a waterproof-breathable outer shell are recommended. Adjust your layers frequently as your activity level changes. While the risk of lightning is low, remain vigilant against the combined effects of wind chill and wetness.

Light rain is also expected to continue into the evening and night, with temperatures remaining stable. Nighttime travel would involve further reduced visibility, making it prudent to complete your descent during daylight hours. While travel is feasible, extreme caution is necessary due to poor visibility and wet footing, especially on rocky sections where the risk of slipping is elevated.
