羅臼岳 午後から霧雨。濡れた岩稜は滑落注意

Mount Rausu summit currently experiences light cloudy conditions with a temperature of 8.4℃, feeling like 7℃. The base is cloudy at 15.7℃, indicating a significant temperature difference. Light drizzle is expected to begin around noon, with precipitation probability increasing to 45-63% in the afternoon and continuing into the evening. Winds are generally light, with gusts peaking at around 6.3 m/s, posing a low risk of strong winds.

The light drizzle and cool temperatures will lead to wet and muddy ground conditions. Particular caution is advised on the rocky sections of the Iwaobetsu Course and Rausu Course, as they will become slippery. Careful footing is crucial to prevent falls. With no snow accumulation, crampons or microspikes are not necessary.

While the felt temperature remains around 7℃, the risk of hypothermia increases due to the persistent drizzle and low temperatures. A base layer, a mid-layer such as fleece, and a waterproof-breathable outer shell are essential. Carry gloves and a hat, and change into dry clothes or add layers during breaks. Always consider the potential for dense fog due to the sea winds in Shiretoko, and be prepared for reduced visibility. This is also active brown bear season, so a food locker is mandatory.

Temperatures will drop to 5℃ overnight with continued drizzle. It is strongly recommended to conclude all outdoor activities during daylight hours and seek safe shelter.
