Typhoon Dolphin stopped being numbered at 5 pm on Tuesday, however its impacts continue as it triggered strong winds and heavy rainfall in inland areas as far north as Beijing. The National Meteorological Center (NMC) issued an orange alert for heavy rain, along with blue alerts for severe convective weather. Some areas are expected to see rainfall of 250 to 300 millimeters, CCTV News reported on Tuesday.

台风海豚于周二下午17点停止编号，但余威仍在，因为它在北至北京的内陆地区引发了强风和暴雨。国家气象中心（NMC）发布了暴雨橙色预警，以及强对流天气蓝色预警。据央视新闻周二报道，一些地区预计降雨量将达到250至300毫米。

The China Meteorological Administration maintained a Level II emergency response on Tuesday as Typhoon Dolphin, its remnants, and cold air were forecast to bring heavy rain to parts of eastern and northern China including Zhejiang, Jiangsu, Anhui, Hubei, Henan, Shandong, Shanxi, Hebei and Beijing over the next three days, CCTV reported.

据中央报道，中国气象局于周二维持二级应急响应，预报显示，未来三天，台风“海豚”及其残余环流将配合冷空气为我国东部和北部多地带来强降雨，涉及浙江、江苏、安徽、湖北、河南、山东、山西、河北和北京等地。

From Tuesday morning to Wednesday morning, parts of multiple regions including western Jiangsu, north-central Anhui, Henan, central and western Hubei, western and southern Hebei, Beijing, central and western Inner Mongolia, northwestern Heilongjiang, and southwestern Yunnan are expected to experience heavy to torrential rainfall. Some areas in central Henan could see extreme rainfall, with accumulated precipitation reaching 250 to 300 millimeters, according to CCTV.

据央视消息，周二早晨至周三早晨，江苏西部、安徽中北部、河南全境、湖北中西部、河北西部和南部、北京、内蒙古中西部、黑龙江西北部、云南西南部等多个地区将迎来大到暴雨。河南中部一些地区可能会出现极端降雨，累计降水量将达到250至300毫米。

Beijing activated a Level II flood-control emergency response at 9 am on Tuesday, with authorities at all levels throughout the city mobilizing flood prevention measures, CCTV reported. Meanwhile, the Ministry of Natural Resources launched a Level IV geological disaster defense response for Beijing at 3 pm on Tuesday.

据中央电视台报道，北京市于周二上午9时启动防汛二级应急响应，全市各级政府动员落实各项防洪措施。与此同时，自然资源部于周二下午3时针对北京启动地质灾害四级防御响应。

According to the Beijing Meteorological Service's forecast, from Tuesday evening through Thursday, most parts of Beijing will experience heavy rainfall, with accumulated precipitation expected to exceed 100 millimeters in six hours and 150 millimeters in 24 hours.

据北京市气象局预报，周二傍晚到周四，北京大部分地区将迎来强降雨过程，预计6小时累计降水量将超过100毫米，24小时累计降水量将超过150毫米。

In seven areas including Tongzhou, Daxing, Fangshan, Mentougou, the Beijing Economic-Technological Development Area, Huairou, and Fengtai, six-hour rainfall totals could exceed 150 millimeters, while 24-hour accumulations could surpass 200 millimeters, CCTV reported.

据中央电视台报道，通州、大兴、房山、门头沟、北京经济技术开发区、怀柔和丰台这七个地区，6小时总降雨量或超150毫米，而24小时累计降雨量或将突破200毫米。

Beijing receives an average of 528 millimeters of precipitation annually, with most of it typically concentrated between June and September. Therefore the rainfall in 24 hours since Tuesday evening would likely be equivalent to more than one-third of the city's annual rainfall.

北京年平均降水量为528毫米，降水大多集中在6月至9月。因此，自周二晚上起24小时内降雨量或将超过该市年降雨量的三分之一。

Beijing's flood control authorities ordered personnel responsible for urban waterlogging hotspots to take their posts from noon on Tuesday, with drainage equipment and flood barriers pre-positioned.

北京防汛部门要求负责城市内涝险点的工作人员从周二中午开始上岗，排水设备和防洪堤预先就位。

The city's flood control authorities also ordered the evacuation of people in flood- and landslide-prone areas before 6 pm on Tuesday and required work at construction sites to be suspended and mountain campsites and related tourist attractions to be closed.

该市防洪当局还下令在周二下午18点前疏散洪水和山体滑坡易发区域的群众，并要求建筑工地暂停施工，关闭山区露营地和相关旅游景点。

Starting Wednesday, Beijing will encourage flexible work arrangements and staggered commuting, while schools may suspend classes and offline training, as well as outdoor teaching activities. Outdoor sports events will be halted, traffic controls imposed in high-risk areas, and public transport adjusted according to weather conditions and safety needs, CCTV reported.

据央视报道，自周三起，北京鼓励弹性工作安排、错峰通勤；学校可暂停授课和线下培训及户外教学活动。户外体育赛事将全部暂停，高风险区域将实施交通管制，公共交通将根据天气状况与安全需要动态调整。

As significant rainfall is expected to begin affecting western and southern parts of Shandong Province on Tuesday, Jinan city has taken precautionary measures in advance, with multiple large and medium-sized reservoirs carrying out controlled pre-releases to create additional flood-control capacity and prepare for rainfall brought by the typhoon, CCTV reported.

据央视报道，由于预计周二山东省西部和南部地区将迎来明显降雨，济南市已提前落实各项防范措施，多座大中型水库有序开展可控预泄洪，提升防洪库容，应对台风带来的降雨。

In Henan Province, the provincial department of water resources and provincial meteorological service jointly issued a red alert for flash floods at 8 am. It is forecast that from 8 am Tuesday to 8 am Wednesday, some mountainous areas in multiple cities and counties are at relatively high risk of flash flood.

在河南省，省水利厅和省气象局于上午8点联合发布山洪红色预警。据预测，周二上午8时至周三上午8时，省内多个市县的部分山区发生山洪风险较高。

Typhoon Dolphin's impact is far from over despite the typhoon having made landfall twice in Zhejiang. Zhang Fanghua, chief forecaster at the NMC, said on Monday that Dolphin's extensive cloud system and abundant moisture reserves have prevented its residual circulation from dissipating quickly. Instead, the residual circulation is expected to continue moving northward and westward. Over the next week, it is forecast to bring widespread and prolonged heavy rainfall to East China, North China, the Huanghuai region and even Northeast China, with some areas potentially experiencing extreme rainfall, the Science and Technology Daily reported.

尽管台风“海豚”已两次在浙江登陆，但它带来的影响远未结束。NMC首席预报员张芳华于周一称，台风“海豚”庞大的云系统以及丰沛的水汽，使其残余环流无法快速消散。后续，该残余环流将持续向北、向西移动。据《科技日报》报道，未来一周，华东、华北、黄淮以及东北多地区将出现大范围持续性的强降雨，部分地区可能出现极端暴雨。

Ma Jun, director of the Institute of Public and Environmental Affairs, told the Global Times that as the typhoon moves northward, it could encounter cold air from the north, potentially bringing not only heavy rainfall but also severe convective weather. Such weather can trigger disasters such as flash floods and mudslides, cause urban flooding, and affect farmlands.

公众环境研究中心主任马军在接受《环球时报》采访时表示，台风北上过程中或将与北方的冷空气相遇，除强降雨以外，还极易诱发剧烈的强对流天气。此类天气极易引发山洪、泥石流等地质灾害，造成城市内涝，影响农田造成不利影响。
