最强降雨
the heaviest downpour

Beijing experienced the heaviest downpour since the start of this year's flood season on Wednesday evening after a day of on-again, off-again downpours that saw flights canceled, parks closed, homestay hotels shut and city workers on standby for floods and other emergencies.
经过白天断断续续的降雨之后，8月12日夜间，北京遭遇今年入汛以来最强降雨。此次降雨导致航班取消、公园和民宿关闭，市政洪涝应急响应工作人员待命。
