霧雨と低温続く。濡れ対策と低体温症に厳重警戒

Mount Iwate summit experiences continuous heavy mist and rain this morning, with temperatures at 1.1℃ and a feels like temperature of -1.7℃. The 95% humidity means getting wet will rapidly lead to hypothermia. Essential layering includes a moisture-wicking base, a fleece or light down mid-layer, and a waterproof-breathable shell as an outer layer. Always carry spare warm clothing.

The ground is predominantly exposed rock with no snow cover, but the mist and rain have made surfaces wet. Many sections will be muddy, requiring extra caution on slippery terrain. Gusts are forecast to reach up to 8.3m/s during the day. Given Mount Iwate's nature as an isolated peak, areas above the tree line will be significantly affected by wind. Particular attention is needed on the crater rim of Yakushidake, known as Ohatsumeguri, where gusts can destabilize footing and dislodge loose rocks.

The risk of hypothermia remains very high. Ensure thorough wet weather protection and maintain body warmth during breaks. Exercise extreme caution in deciding whether to proceed with your ascent. The weather is expected to improve to clear skies around 3 PM, but temperatures will drop below freezing overnight, with potential for icy patches on trails. Always check the latest volcanic alert level before starting your ascent.
