現在の九重連山山頂は強い雨、気温14.7℃、体感12.7℃。南西からの風は6.41m/sだが、突風は19.5m/sに達している。視程は1.5kmと低く、濃い霧に包まれている状況だ。今日日中は弱い雨に変わる時間帯もあるが、夕方以降は再び雨脚が強まる予報で、夜半には降水量が25mmに達する強い雨が予想される。
行動中の体感気温は12℃から15℃程度で推移するが、強い雨と突風で体が濡れると体温が急速に奪われる。低体温症のリスクが極めて高いため、防水透湿性のレインウェア上下は必須装備だ。ベースレイヤーには速乾性の化繊またはメリノウール長袖、ミッドレイヤーには薄手のフリースやソフトシェルを選び、休憩時や風の強い場所での保温着として薄手の化繊インサレーションジャケットを携行すること。
地面は強い雨が続いているため、登山道全体が深く濡れており、泥濘が広がる。特に牧ノ戸峠コースから久住山方面へ向かう稜線や、岩が露出した箇所は滑りやすく、転倒や滑落の危険性が高い。また、視程1.5kmという状況では、九重連山特有の霧による道迷いリスクも高まる。安易な行動は避け、地図とコンパス、GPSを携行し、常に現在地を確認しながら進むこと。坊ガツル湿原周辺のような開けた場所でも強風に晒されやすい。
現時点での雷のリスクは低いが、強い雨と突風が続くため、今日の登山は推奨しない。特に稜線での行動は危険が伴う。無理な行動はせず、天候の回復を待つか、短時間で引き返せる計画で、十分な装備と経験者との同行を徹底すること。夜半にはさらに天候が悪化するため、日没前の下山を厳守すること。

The summit of Kuju Mountains currently experiences heavy rain, with a temperature of 14.7°C and a feels-like temperature of 12.7°C. The wind from the southwest is 6.41m/s, but gusts are reaching 19.5m/s. Visibility is low at 1.5km, indicating dense fog. While the rain may lighten at times today, it is forecast to intensify again in the evening, with heavy rain and precipitation reaching 25mm expected by midnight.
During activity, the feels-like temperature will hover between 12°C and 15°C. However, heavy rain and strong gusts can rapidly strip body heat, significantly increasing the risk of hypothermia. Waterproof and breathable rainwear (jacket and pants) is therefore essential. For layering, choose a quick-drying synthetic or merino wool long-sleeve base layer, a thin fleece or softshell for a mid-layer, and carry a lightweight synthetic insulated jacket for warmth during breaks or in windy areas.
Due to continuous heavy rain, all trails are deeply saturated and muddy. The trails, especially the exposed ridges along the Makinoto Pass course towards Mount Kuju and rocky sections, are extremely slippery, posing a high risk of falls and slips. Furthermore, with visibility at 1.5km, the risk of getting lost in the unique Kuju fog is elevated. Avoid reckless actions; carry a map, compass, and GPS (with spare battery), and constantly confirm your location. Open areas like the Bogatsuru Wetlands are also susceptible to strong winds.
While the risk of lightning is currently low, persistent heavy rain and strong gusts make hiking inadvisable today. Ridge travel, in particular, carries significant danger. Refrain from pushing your limits, wait for improved weather, or plan a short trip with a clear turnaround time, ensuring you have adequate gear and are accompanied by experienced individuals. As weather conditions will worsen further by midnight, strict adherence to descending before sunset is crucial.
