大切なメモ:下のカードは、ブラウザでOpen-Meteoの3日予報を取得して更新します。気象庁の警報・注意報、土砂災害警戒情報、指定河川洪水予報、熱中症警戒アラート、台風情報、自治体の避難情報を必ず確認してください。千葉の被災地域では、雨が弱くても河川、低地、道路、斜面、停電、鉄道・空港アクセスの状況が変わる可能性があります。全国では危険な暑さと午後の局地的な雷雨に備えてください。
Important note: Cards update in-browser using Open-Meteo. Always check JMA and local governments for official forecasts, warnings, river and landslide information, heatstroke alerts and evacuation instructions. In flood-affected Chiba, river levels, roads, slopes, power and transport access may remain disrupted even when rain is light. Across Japan, prepare for dangerous heat and fast-forming afternoon thunderstorms.

天気の英語も、日本語も、毎日すこしずつ。Today’s page borrows Bertha Lum’s atmospheric color-woodblock language: misty blue-green layers, water, trees, softly patterned skies and small pools of moonlike light. This is an editorial homage, not an original Lum print or a substitute for weather evidence.

Forecast source: Prepared for August 17–19, 2026. The 47 representative-city cards request current Open-Meteo data in the browser. Safety context gives priority to Japan Meteorological Agency warnings and forecasts, MLIT river information, local-government notices and transport-operator updates. Automated model output can differ from official local forecasts and can change after publication.
Weather desk context: Record rainfall in Chiba damaged homes, roads and airport access before this edition. Recovery conditions can remain hazardous after rain eases. Heat, humidity and localized thunderstorms also remain mid-August risks. This page is for planning and language learning; it is not an emergency service.
