晴天の朝、午後から霧雨。濡れ対策怠るな

As of 7:15 AM, Tomuraushi Mountain summit is clear with excellent visibility exceeding 20km. The temperature is 9.4°C, feeling like 7.7°C, with almost no wind at 0.76m/s. The temperature difference from the base is 7.2°C, highlighting the chill at higher altitudes.

While the morning remains clear, light drizzle is expected to begin around noon, increasing to 0.9mm by 3 PM. Winds will remain light, with gusts peaking around 5.1m/s. Trails are currently dry, but the afternoon drizzle will make areas around Hokunuma and Minaminuma wetlands, as well as the Rock Garden's giant boulders, wet and potentially slippery.

The felt temperature at 2133.35m will range from 7-10°C throughout the day. Layering should include a wicking base layer, a light fleece or wool mid-layer, and a waterproof-breathable outer shell. Always carry an insulating layer like a down jacket or a thicker fleece for breaks or sudden weather changes. Remembering the lessons from the 2009 accident, be prepared for severe weather changes comparable to 3000m peaks on Honshu.

While the risk of lightning and strong winds is low, afternoon drizzle increases the risk of hypothermia. On this long, challenging course, getting wet can severely deplete your energy. After 6 PM, light drizzle will transition to cloudy skies, with temperatures gradually dropping to around 5°C overnight. Ensure thorough wet weather protection and insulation for safe travel.
