日中視界回復。残雪と凍結箇所に注意

The current summit conditions on Mt. Rausu are cloudy with visibility less than 1km and a wind chill of -9.7°C, a significant 7.5°C colder than the base. Hikers on the Iwaobetsu Course and Rausu Course should be wary of icy sections, especially above the treeline and on shaded, wind-exposed snow patches where residual snow may have turned to ice. Conditions are expected to improve throughout the day, with forecasts indicating partly sunny skies by 12:00 and clear skies by 15:00. Temperatures will also rise, reaching 0.3°C by mid-afternoon, improving the perceived temperature. Winds are also expected to diminish.

While the daytime warming will soften some frozen surfaces, carrying microspikes or light crampons is advised for the morning due to potential icy sections. Given the summit's cold wind chill, a base layer, a fleece mid-layer, and a windproof outer shell are essential. Adjust your layering frequently to mitigate the risk of hypothermia. As Shiretoko is prime bear habitat, ensure all food is stored in bear-proof containers or food lockers, and carry bear spray.

Temperatures will drop below freezing again after sunset. Although the forecast is for partly cloudy skies, avoid nighttime travel. Seize the opportunity of improved visibility during the day, but always proceed with caution.
