23:51 Update: Heavy/Torrential Rain Advisory Expands to Northern and Yilan Mountain Areas; 13 Liugui Yellow Alerts Continue
Information time: September 1, 2026, 23:51.
Official sources: Central Weather Administration heavy/torrential-rain advisory, synchronized by the Water Resources Agency at 18:50; Agency of Rural Development and Soil and Water Conservation 21:30 September 1 heavy-rain report No. 3; Directorate-General of Personnel Administration real-time work/class page; Highway Bureau; Water Resources Agency disaster-information service; and relevant local-authority notices.
Latest material change: The heavy/torrential-rain advisory expanded. New Taipei, Taoyuan, Kaohsiung, Pingtung and Yilan mountain areas may see localized heavy or torrential rain; Hsinchu, Miaoli, Yunlin through Tainan, Yilan and Taitung may see localized heavy rain. For monitored Indigenous areas, Wulai in New Taipei, Fuxing in Taoyuan, and Datong/Nan'ao in Yilan are `weather / watch` for heavy or torrential-rain risk; Jianshi/Wufeng in Hsinchu and Nanzhuang/Tai'an in Miaoli are `weather / watch` for heavy-rain risk. These are watch conditions, not `red`.
Slope alerts: The 21:30 third report from the Agency of Rural Development and Soil and Water Conservation still lists 13 debris-flow yellow alerts in Wenwu, Dajin and Zhongxing villages of Liugui District, Kaohsiung. Debris-flow red alerts remain at zero; large-scale-landslide red and yellow alerts both remain at zero. Liugui is `yellow` and must not be relabeled as `red` for Maolin, Taoyuan, Namasia or other Indigenous areas.
Work/class and roads: The latest Directorate-General of Personnel Administration page still lists Shiwen Village in Chunri Township as suspending work and classes on September 2. The Highway 24 43K+700 blockage in Wutai has reopened. Separate controls on the temporary Provincial Highway 20 Route 105 Meishankou-Xiangyang section between Kaohsiung Taoyuan and Taitung Haiduan continue under Highway Bureau notices. For the Highway 7A 61K Huanshan tree-fall event in Heping, no formal reopening notice was identified in this scan, so `transport / watch` is retained.
Nationwide regional scan — North: Wulai, Fuxing, Jianshi, Wufeng, Nanzhuang and Tai'an are `weather / watch`, not red.
Nationwide regional scan — Central: Alishan is `weather / watch`; Heping retains its existing `transport / watch`; Ren'ai and Xinyi remain `monitoring`.
Nationwide regional scan — South: Tainan mountain areas, Kaohsiung Taoyuan/Namasia/Maolin, and monitored Pingtung Indigenous areas including Sandimen, Wutai, Majia, Taiwu, Laiyi, Chunri, Shizi and Mudan are `weather / watch`. Liugui's 13 debris-flow-prone streams are `yellow`, and Shiwen Village also has `work-school / watch`.
Nationwide regional scan — East: Datong/Nan'ao in Yilan and monitored Taitung Indigenous areas including Beinan, Yanping, Haiduan, Daren, Jinfeng, Taimali, Dawu and Lanyu are `weather / watch`. Hualien's Xiulin, Wanrong and Zhuoxi remain `monitoring` in this scan.
Water and other conditions: At 20:00 the Water Resources Agency listed a level-two river-water warning in Gaoshu Township, Pingtung, and Mudan Reservoir remained in release status at 19:00. Neither is a level-one inundation alert or a red alert. No new level-one inundation alert, debris-flow red alert, large-scale-landslide escalation, formal evacuation, shelter activation, major agricultural-loss warning, or major water/power/public-service interruption affecting monitored Indigenous areas was identified.
Alert level: The site's overall level remains `watch`; Liugui is `yellow`; there is no red alert in this scan.
Recommended action: Avoid streambeds, steep slopes and rockfall-prone mountain roads in northern Taiwan, Yilan, southern Taiwan and Taitung while short-duration intense rain remains possible. Yellow-alert communities in Liugui should follow local-government and soil-and-water-conservation evacuation-preparedness advice. Shiwen Village should follow the September 2 work/class suspension notice. Stay out of riverbeds downstream of Mudan Reservoir and in river-water-warning areas. Other areas should follow real-time notices from the competent authorities.
Official notices govern.
20:07 Update: Kaohsiung-Pingtung Heavy/Torrential Rain Advisory Continues; 13 Liugui Debris-Flow Yellow Alerts; Shiwen Closed September 2
Information time: September 1, 2026, 20:07.
Official sources: Central Weather Administration 16:00 heavy/torrential-rain advisory; Agency of Rural Development and Soil and Water Conservation 18:30 September 1 heavy-rain report No. 2; Directorate-General of Personnel Administration 18:25:16 work/class update; Highway Bureau 16:23 Wutai reopening notice; Water Resources Agency flood-information service; and relevant local-authority notices.
Weather and slope alerts: The Central Weather Administration's 16:00 advisory stated that Kaohsiung and Pingtung could see localized heavy or torrential rain, while areas from Yunlin through Tainan, Taitung, Orchid Island, Green Island and other listed areas could see localized heavy rain. Related Indigenous areas are `weather / watch`, not `red`. At 18:30, the Agency of Rural Development and Soil and Water Conservation issued 13 debris-flow yellow alerts in Liugui District, Kaohsiung, covering Wenwu, Dajin and Zhongxing villages. Debris-flow red alerts remained at zero, and large-scale-landslide red and yellow alerts both remained at zero. Liugui's yellow alert is an important regional warning adjacent to southern Indigenous areas, but it must not be relabeled as a red alert for Maolin, Taoyuan or Namasia. The agency states that local governments should issue evacuation-preparedness advice for yellow-alert areas.
Work/class change: The Directorate-General of Personnel Administration's 18:25:16 update explicitly lists Shiwen Village in Chunri Township as suspending work and classes on both September 1 and September 2. Changle Village in Manzhou Township is currently listed only for September 1. Shiwen therefore remains `work-school / watch` and extends into September 2; the status must not be expanded to all of Chunri Township or other Pingtung Indigenous areas.
Road correction: The Highway Bureau formally announced at 16:23 that the Highway 24 43K+700 slope collapse in Wutai Township had been cleared by 16:00 and the road returned to normal traffic. The earlier `transport / watch` for that specific blockage is therefore cleared, although Wutai remains `weather / watch` under the Pingtung rain advisory. Separate controls on the temporary Provincial Highway 20 Route 105 Meishankou-Xiangyang section between Kaohsiung Taoyuan and Taitung Haiduan continue under the Highway Bureau's latest notices.
Nationwide regional scan — North: Wulai, Fuxing, Jianshi, Wufeng, Nanzhuang, Tai'an and other monitored northern Indigenous areas remain `monitoring`, with no new threshold-level official change identified.
Nationwide regional scan — Central: The CWA advisory's Yunlin-through-Tainan heavy-rain corridor includes the Chiayi area, so Alishan is `weather / watch`. Heping retains its existing transport observation status. Ren'ai and Xinyi remain `monitoring`.
Nationwide regional scan — South: The Tainan mountain area, Kaohsiung Taoyuan, Namasia and Maolin, and monitored Pingtung Indigenous areas including Sandimen, Wutai, Majia, Taiwu, Laiyi, Chunri, Shizi and Mudan are `weather / watch`. Wenwu, Dajin and Zhongxing villages in Liugui are under official debris-flow yellow alert. Shiwen Village also has `work-school / watch`.
Nationwide regional scan — East: Monitored Taitung Indigenous areas including Beinan, Yanping, Haiduan, Daren, Jinfeng, Taimali, Dawu and Lanyu are `weather / watch`. Haiduan also retains its existing `transport / watch`; Beinan, Haiduan and Dawu continue under forest-recreation `public-service / watch` conditions. No new threshold-level official change was identified for Yilan or Hualien in this scan, so those areas remain `monitoring`.
Flood and other conditions: The Water Resources Agency inundation-alert page showed Taiwan below inundation-alert thresholds in this scan. No new level-one inundation alert, debris-flow red alert, large-scale-landslide alert, formal evacuation, shelter activation, major agricultural-loss warning, or major water/power/public-service interruption affecting monitored Indigenous areas was identified.
Alert level: The site's overall level remains `watch`. Liugui is `yellow`; relevant Kaohsiung, Pingtung, Chiayi-Alishan, Tainan-mountain and Taitung Indigenous areas are `weather / watch`; Shiwen Village is `work-school / watch`; the specific Highway 24 blockage in Wutai has been cleared. There is no red alert in this scan.
Recommended action: Avoid streambeds, steep slopes, and rockfall-prone mountain roads in Kaohsiung, Pingtung and Taitung during short-duration intense rain. Wenwu, Dajin and Zhongxing villages in Liugui should follow local-government and soil-and-water-conservation yellow-alert evacuation-preparedness advice. Shiwen Village should follow the September 2 work/class suspension notice. Other areas should follow real-time notices from the competent authorities.
Official notices govern.
