斜里岳：午後から霧雨の予報。濡れた岩場と沢筋に注意

午前7時15分現在、斜里岳山頂は快晴、気温12℃、風速0.81m/sと穏やかな状況です。山麓も快晴で16.7℃と、山頂との気温差は4.7℃。日差しは強いものの、標高が上がるにつれて気温は下がり、体感温度は11.4℃となっています。日中の行動はベースレイヤーとミッドレイヤーで十分ですが、休憩時や稜線に出た際に羽織る防風防寒シェルは必須です。今日の予報では、正午頃から次第に雲が広がり、午後3時には弱い霧雨が始まり、降水確率も90%に達します。午後6時まで霧雨が続く見込みです。この降雨により、旧道（連続する滝）の沢筋は水量が増え、岩や木の根が濡れて滑りやすくなります。新道の稜線上の岩場も同様に足元が不安定になるため、滑落には厳重な警戒が必要です。自動リスク判定では、予報期間中に6℃の急激な気温低下が見込まれています。午後3時の13.9℃から、夜間にかけて8.5℃まで低下します。霧雨で体が濡れると、この気温低下は低体温症のリスクを大きく高めます。出発前から防寒レイヤーを一枚多めに携行し、雨具は必ず上下で着用してください。天候悪化や体力の消耗を感じたら、無理せず早めに引き返す判断が命を守ります。雷の心配はありませんが、夕方以降は突風8m/sを超える可能性があり、行動時間帯を短縮することが賢明です。
