午後は急変 沢筋の増水と低体温症に注意

Currently, Mount Shari summit is clear with a temperature of 9°C, feeling like 5.4°C. Visibility is excellent, promising good views of the Sea of Okhotsk. Mostly clear conditions will prevail until around 9 AM, with the temperature rising slightly to 10.5°C. During this period, conditions are relatively calm, and the ground remains dry. A base layer, a light mid-layer, and a windproof outer shell should suffice, with adjustments made by layering.

However, by noon, it will become cloudy, and the temperature will drop to 6.8°C. Light rain is expected to start around 3 PM, with a rapid temperature plunge to -2.5°C. A significant temperature drop of 18°C is forecast throughout the period, necessitating vigilance for sudden changes during your activity. Specifically, on the Old Route (Kyudo) with its continuous waterfalls and stream sections, rainfall will increase the risk of rapid water level rise and slippery rocks. Being wet and exposed to wind severely elevates the risk of hypothermia. Therefore, carrying warm insulating layers such as a thick fleece or down jacket is essential, and reliable waterproof rain gear is a must-have.

Gusts up to 14.7 m/s are expected, which could make traversing exposed ridges challenging. As Mount Shari is a habitat for brown bears, extra caution is advised, especially as rain can reduce visibility and make it harder to hear surrounding sounds over the stream noise. It is recommended to reach the summit in the morning and begin your descent by 1 PM at the latest. Early decision-making to turn back is crucial.

After 6 PM, it will remain cloudy, with temperatures ranging from
