谷川岳：濃霧と湿潤な稜線。低体温症とルートロストに警戒

現在の谷川岳山頂は曇り、視程1km未満の濃霧状態にある。気温10.9℃、湿度99%と非常に湿潤で、山麓の18.2℃と比較して大幅に低い。午前中は曇り基調だが、15時頃から弱い雨が降り始める予報。午後にかけて突風は最大10.8m/sに達する時間帯もあり、体が濡れると体感温度は一層低下する。地面は終日ウェットコンディションが続く。岩稜帯は滑りやすく、特にトマの耳、オキの耳周辺の稜線では、濃霧によるルートロストのリスクが極めて高い。谷川岳は短時間の気象急変が起こりやすい気候境界に位置しており、視界不良時には進行方向を誤る危険が増す。行動中は、ベースレイヤーに吸湿速乾性、ミッドレイヤーに保温性のあるフリースや薄手ダウン、アウターは防水透湿性のシェルを着用し、濡れによる低体温症を厳重に警戒すること。雨具は必ず携行し、早めの着用を心がける。視界が確保できない状況での無理な進行は避け、引き返す判断が重要となる。夕方から夜間にかけても霧雨が続き、気温は12℃台で推移する。夜中には一時的に晴れ間が覗く予報だが、日中の視界不良と湿潤な環境を考慮し、早めの行動開始と下山を推奨する。
