China's National Commission for Disaster Prevention, Reduction and Relief and the Ministry of Emergency Management activated a Level-IV national disaster relief emergency response for South China's Guangxi Zhuang Autonomous Region on Monday after Typhoon Narra, the 19th typhoon of this year, caused severe flooding in the region that led to passenger train suspensions. A working group was sent to the affected areas to assess damage and assist with evacuations, resettlement and basic relief efforts, China Central Television (CCTV) reported on Monday. 
The China Meteorological Administration raised its emergency response for major weather disasters, including typhoons, torrential rain and severe convective weather, to Level III at 11:50 am on Monday. 
China's National Meteorological Center (NMC) continued to issue a yellow alert for rainstorm and a blue alert for typhoon at 6 am on Monday, forecasting torrential rainfall in parts of coastal regions as well as Liaoning and Heilongjiang provinces. The rainfall on Taiwan Island is forecast to reach 250 to 300 millimeters between Monday morning and Tuesday morning, CCTV reported. 
Typhoon Narra was located over the Beibu Gulf about 185 kilometers west-southwest of Beihai, Guangxi, at 5 am on Monday, with maximum winds of 23 meters per second near its center. 
It is expected to linger over the Beibu Gulf and strengthen to severe tropical storm, with winds of up to 25 to 28 meters per second. From Monday night, it will turn northward and move at 5 to 10 kilometers per hour toward the coast from Guangxi to western Leizhou Peninsula in South China's Guangdong Province.
Meanwhile, Typhoon Atsani, the year's 21st typhoon, formed Monday morning. Its center was located about 1,970 kilometers east-southeast of Taipei of the Taiwan Island at 8 am, and is expected to move north-northeast at 15 to 20 kilometers per hour, with little change in its strength, CCTV reported.

Due to the impact of Typhoon Narra, Ningming county in Guangxi is forecast to see moderate to heavy rain and locally torrential rain from Wednesday to Thursday. In response to typhoon, heavy rainfall and flood warnings, multiple passenger train services have been suspended from Sunday to Thursday, according to CCTV. 
According to Zhang Ling, a chief weather forecaster at the NMC, Typhoon Narra remains stalled over the Beibu Gulf as several surrounding weather systems compete to steer the storm, with none dominant. Meanwhile, warm waters and abundant monsoon moisture are helping Typhoon Narra persist, bringing prolonged rain and strong winds to southern China's coast, the Beibu Gulf and the northern South China Sea.

On Saturday, Fangchenggang in Guangxi recorded a maximum accumulated rainfall of 404.9 millimeters. As more rain is expected in Guangxi and other areas, attention should be paid to the cumulative effects of prolonged rainfall, with southern Guangxi facing heightened risks from heavy cumulative rainfall and intense short-duration downpours, Zhang told the Global Times on Monday. 
According to Ma Jun, director of the Institute of Public and Environmental Affairs, 21 typhoons have formed over the western North Pacific and South China Sea this year, nine more than the historical average for the same period. 
The surge in activity is closely related to the current super El Nino conditions. During an El Nino event, hurricane activity in the Atlantic tends to be suppressed, resulting in fewer storms, while typhoon activity in the western Pacific tends to increase. The number of typhoons formed so far this year is consistent with the typical pattern of typhoon activity during an El Nino year, Ma told the Global Times on Monday. 
。    据中国气象局官微消息，4月19日8时至21日8时，贵州南部、江南南部、华南北部和中东部等地的部分地区出现暴雨到大暴雨、局地特大暴雨。中国气象局于4月18日8时30分启动暴雨三级应急响应。4月21日10时，中央气象台继续发布暴雨橙色预警、强对流天气黄色预警。

B | 　　多地累计降水量突破4月历史纪录，珠江流域北江发生2024年第2号洪水　　19日8时至21日8时，广西北部、广东中北部、湖南东南部、江西南部累计降水量达100毫米至200毫米，其中广西东北部、广东西北部达250毫米至350毫米，局地超过400毫米。最大小时降水量达40毫米至80毫米，广西南宁、广东茂名局地超过100毫米。20日8时30分至9时15分，广西壮族自治区梧州市藤县发生中等强度龙卷风（相当于最大瞬时风力达15级）。　　受强降水影响，珠江流域北江发生2024年第2号洪水。21日早晨，北江下游控制站石角水文站流量为14900立方米/秒，已经超过2024年第1号洪水，并在广西、广东造成多条中小河流水位超警戒水位，多地发生地质灾害。

C | 　　气象部门密切关注此次强降水过程，中国气象局与水利部联合发布山洪灾害气象风险提醒，并联合自然资源部提前启动2024年度全国地质灾害气象风险联合预警业务。广西、广东省（自治区）气象局与当地水利厅、自然资源厅联合发布山洪灾害与地质灾害气象风险预警。　　多重因素导致近期南方降雨偏多偏强，未来强降水过程多仍需加强防范　　中央气象台首席预报员马学款介绍，4月以来，副热带高压比常年同期偏强，有利于南海和孟加拉湾水汽向南方地区输送，同时高原槽和南支系统活跃，导致南方地区强降水过程频繁、降水持续时间偏长。另外，江南、华南等地气温比常年同期明显偏高，大气含水量丰富、不稳定能量高，导致对流发展旺盛、降雨强度高，多地累计降水量突破4月历史纪录。

D | 　　中央气象台预计，4月21日至22日，江南南部和东部、华南中东部和南部等地仍有强降水，局地有大暴雨并伴有雷暴大风或冰雹等强对流天气。23日，华南地区的降雨将明显减弱，但华南南部沿海部分地区仍有大到暴雨。另外，在25日前后，贵州、江南、华南等地还将有一次较强降水过程。

E | 　　马学款提示，未来几天，我国南方地区强降水过程多、局地雨强大，并可能伴有风雹天气，公众需及时关注当地气象部门发布的预报预警信息，在强降水时段减少外出，避免在山涧、河道等低洼地带逗留，注意防雨防雷电，防范山洪、滑坡、泥石流等次生灾害风险。相关部门要注意城市低洼地带及时排水，加固户外设施，防范强风对临时搭建物、高空作业装置和人员、航运等的安全威胁。　　（中国小康网综合中国气象局官微）。
