未来一周华南降水偏多 珠江委提醒防御中小河流洪水和山洪灾害 金十数据5月19日讯，水利部珠江水利委员会会商部署近期水旱灾害防御工作。珠江水情预报中心预 计，未来一周（5月19日—25日），受冷暖空气共同影响，珠江流域中部和北部仍将有持续性降雨过 程，西江干流及支流柳江、桂江等河流来水将继续上涨，强降雨区内发生中小河流洪水、山洪灾害风险 较大。广西北部和中东部，广东中北部，降雨集中区内部分中小河流可能发生超警洪水，提醒相关地区 做好中小河流洪水、山洪灾害防御工作。后续，珠江委强化流域统一调度，将根据汛情发展，滚动优化 大藤峡、长洲等水利枢纽调度方案，充分发挥水库防洪减灾效益。近期，珠江流域旱涝并存，云南旱情 未解除，广西、广东等地已经历多轮强降雨过程。珠江防总、珠江委已于18日同步启动防汛Ⅳ级应急响 应和洪水防御Ⅳ级应急响应。 （央视新闻） ...
