“普拉桑”给华东地区带来强降水
中央气象台9月20日10时继续发布台风蓝色预警：
今年第14号台风“普拉桑”已于今天（20日）上午8点钟在江苏省江阴市境内由热带风暴级减弱为热带低压，其中心位于北纬31.9度、东经120.0度，外围最大风力有7级（15米/秒），中心最低气压为1000百帕。
预计，“普拉桑”将以每小时5-10公里的速度向偏北转东北方向移动，今天夜间移入黄海南部海面，强度将再度发展，移速加快，向韩国南部沿海靠近，并逐渐变性为温带气旋。
大风预报：9月20日14时至21日14时，受“普拉桑”和冷空气的共同影响，渤海、渤海海峡、黄海大部海域将有7-8级大风，阵风9-10级，辽东半岛及沿海、天津大部及沿海、河北南部和东部及沿海、山东大部及沿海、江苏东部沿海、长江口区、杭州湾、上海沿海、浙江中北部沿海等地部分地区将有5-6级风，阵风7-8级。
降水预报：9月20日14时至21日14时，江苏中南部、安徽南部、浙江北部、上海等地部分地区有大到暴雨，其中，江苏南部、上海北部和东部等地部分地区有大暴雨（100-150毫米）。
防御指南：
1.政府及相关部门按照职责做好防台风抢险应急工作。
2.相关水域水上作业和过往船舶应当回港避风，加固港口设施，防止船舶走锚、搁浅和碰撞。
3.停止室内外大型集会和高空等户外危险作业。
4.加固或者拆除易被风吹动的搭建物，人员切勿随意外出，应尽可能待在防风安全的地方，确保老人小孩留在家中最安全的地方，危房人员及时转移。当台风中心经过时风力会减小或者静止一段时间，切记强风将会突然吹袭，应当继续留在安全处避风，危房人员及时转移。
5. 相关地区应当注意防范强降水可能引发的山洪、地质灾害。
