南海热带低压生成并影响华南地区,同时冷空气活跃导致北方昼夜温差增大。
中国天气网讯 未来三天(9月13日至15日),受热带低压影响,海南岛、广东沿海等地风雨持续,局地有大暴雨,同时华西地区阴雨频繁,需防范连续降雨可能引发的次生灾害。北方大部降水较少,昼夜温差较大,白天体验秋高气爽的感觉,早晚凉意明显,需适时调整着装。
海南等地强降雨连连 华西地区阴雨频繁
昨天上午,南海热带低压生成,受其影响,海南等地出现强降雨,同时东北地区和西南地区一带也有降雨。监测显示,昨天,受南海热带低压和冷空气共同影响,海南岛大部出现暴雨,东南部地区出现大暴雨,琼中、万宁和陵水等局地特大暴雨,海南岛东部和南部沿海、广东沿海、福建沿海等地出现7至9级阵风,海南岛南部局地阵风超过10级。
今晨5时,南海热带低压的中心位于海南省三亚市西南方向约205公里的南海中西部海面上,预计将以每小时10-15公里的速度向偏西方向移动,强度变化不大,将于今天下午至夜间在越南中部一带沿海登陆,登陆后强度逐渐减弱。
受热带低压影响,未来三天,海南岛、广东沿海、广西沿海等地部分地区有大到暴雨,局地大暴雨。同时,华西地区阴雨频繁,西北地区中东部、西南地区部分地区有中到大雨。
具体来看,中央气象台预计,今天,海南岛、广东大部、福建南部、广西南部以及黑龙江东部、川西高原南部、西藏东南部等地部分地区有中到大雨,其中,广东西南部、海南岛中南部等地部分地区有暴雨,海南岛南部局地大暴雨,单点有特大暴雨。
明天,海南岛、广东西南部、广西南部、四川盆地北部、川西高原中北部、西藏东部等地部分地区有中到大雨,其中,海南岛西部和南部等地部分地区有暴雨,局地大暴雨。
后天,四川盆地、川西高原中部、广西南部、广东中东部、海南岛中西部、西藏东南部等地部分地区有中到大雨,其中,重庆西部、四川东部等地局地有暴雨。
气象部门提醒,海南岛等地未来三天还将有强降雨,需防范连续降雨可能引发的山洪、滑坡等灾害,同时部分沿海海面风力较强,需注意海上作业安全。陕西西南部、四川部分地区近期累计雨量大,需关注持续性降雨可能引发的次生灾害及对农业生产等方面的不利影响。
北方多地体验秋高气爽 昼夜温差较大
北方大部降水较少,大部地区气温将维持在接近或小幅偏高于常年同期的状态,超过30℃的地方不多,体验秋高气爽的感觉。
由于缺少云层的保温作用,北方大部夜间气温下降较快,昼夜温差较大,普遍将超过10℃,部分地区可以达到15至20℃。像太原,未来三天最高气温在27至28℃,但最低气温仅6至11℃,公众早出晚归请适时添衣,谨防感冒。
