Typhoon Bavi-intensified monsoon rains triggered landslides in the Philippines' Sarangani province and Mindanao, killing at least 15 people, Al Jazeera reported. More than 500 flights were cancelled across China, Taiwan and the Philippines. The storm had moved on from Taiwan toward China's Fujian and Zhejiang coast, with China's National Flood Control headquarters convening a national emergency meeting. ↗

Taiwan's Central Weather Administration issued a land warning for Typhoon Bavi in the early hours of July 10, escalating from the earlier sea warning. The CWA said the typhoon's greatest impact on Taiwan was expected from Friday evening through Saturday. Taipei schools closed on July 10. China Daily reported Bavi weakened from its peak intensity but said its impact would remain severe given the storm's large size. ↗

CGTN reported Bavi was on track to make landfall along China's east coast on Saturday after clearing Taiwan, with Chinese authorities issuing emergency alerts for coastal provinces. Asia Financial noted Japan was also on alert alongside Taiwan and China as the storm's reach extended across three countries. ↗
摘要
台风巴威于7月初以五级台风强度席卷关岛及北马里亚纳群岛后,其眼墙于7月9日逼近台湾东北部。台湾中央气象署于当地时间下午2时30分发布海上警报,警示台湾东部地区及南部巴士海峡面临的危险加剧。中央气象署预测台湾北部山区降雨量至周日累积最高可达900毫米,并就超过6米的海浪发布了该机构史上首次「巨浪」特报。中央气象署气象员张嘉祥表示,这种规模的台风「近年来相当罕见」,该机构认定巴威是1987年以来以规模袭台的最大台风。《台北时报》亦有相同评估。风暴眼墙于当地时间中午前后沿台湾东北部宜兰县一带移动。Rappler同时报道中国正严阵以待。
分歧
台湾本地媒体(Taiwan News、Focus Taiwan)聚焦精确的气象影响、海上警报时间及量化的雨量和浪高数据。菲律宾媒体Rappler是唯一将中国受影响情况与台湾并列报道的来源,以区域视角而非单纯的台湾视角呈现此次风暴。中央气象署明确定义为「史上首次」类别的「巨浪」特报,在Focus Taiwan的报道中受到重点关注,但在Rappler的报道摘要中并未提及。
数据
- 900毫米,台湾北部山区至周日的最高降雨量预测
- 6米,触发中央气象署史上首次「巨浪」特报的浪高
- 1987年,上一次同等规模台风袭台的年份
- 周四下午2时30分(当地时间),中央气象署发布海上警报的时间
重要性
巴威逼近台湾东北部之前,已以五级强度对关岛和罗塔岛造成灾难性破坏。这一规模的台风袭击台湾北部多山地形,带来的山体滑坡和洪涝风险远超沿岸损失,历时数日的900毫米降雨预测更放大了这一风险。中央气象署决定发布史上首次「巨浪」特报,表明该机构将此次台风视为不寻常的沿岸气象灾害,而非例行登陆事件。中国沿海省份是台风路径上的下一站。
关注点
- 台湾东北部至周日实际降雨量及山体滑坡或洪涝灾情报告
- 台风向中国福建或浙江海岸移动时是否保持强度
- 中央气象署根据台风路径相对台湾陆地的位置,调整或升级警报的情况
- 眼墙离台后的伤亡及基础设施损失评估
