Heavy and Torrential Rain Advisories Lifted; South Cross-Island Highway Transport Watch and Wanli River Channel Red Continue
Original Chinese title: 豪（大）雨特報解除；南橫交通watch、萬里溪河道red持續
As of 19:56 on August 29, the Central Weather Administration lists no active heavy or torrential rain advisory. Earlier rain watches across northern, central, southern, and eastern Indigenous areas, as well as the expired severe-thunderstorm and Xiulin mountain-rain messages, are no longer active. The Meishankou-Xiangyang section of the South Cross-Island Highway has not been found formally reopened, so Kaohsiung Taoyuan and Taitung Haiduan remain transport / watch. ARDSWC debris-flow and large-scale-landslide red/yellow alerts remain at zero, DGPA lists no work-or-class suspension, and the site's overall red remains solely for the officially delineated Wanli River channel because no formal lifting notice has been found.

19:56 Update: Heavy and Torrential Rain Advisories Lifted; South Cross-Island Highway Transport Watch and Wanli River Channel Red Continue
Information time: August 29, 2026, 19:56.
Official sources: Central Weather Administration, Highway Bureau, Agency of Rural Development and Soil and Water Conservation, Water Resources Agency disaster information service, Directorate-General of Personnel Administration, Hualien Branch of the Forestry and Nature Conservation Agency, and relevant local authorities.
Indigenous areas affected: CWA's heavy/torrential-rain advisory page lists no active county in this scan. The earlier torrential-rain watches for Jianshi, Wufeng, Nanzhuang, and Tai'an, and the heavy-rain watches for Wulai, Fuxing, Heping, Ren'ai, Xinyi, Alishan, Indigenous areas in Tainan, Kaohsiung and Pingtung, and Indigenous areas in Yilan, Hualien and Taitung are therefore lifted and return to `monitoring`. Earlier severe-thunderstorm messages for Hsinchu/Miaoli and Hualien, and the Xiulin Shapodang Creek mountain-rain disaster alert, have also expired and are no longer active.
Roads and public services: The Highway Bureau's formal notice still states that Provincial Highway 20 temporary route 105, 0K-44K from Meishankou to Xiangyang has been closed since 07:00 on August 28 and will reopen only when weather and road inspections permit. This scan found no formal reopening notice, so Kaohsiung Taoyuan and Taitung Haiduan remain `transport / watch`, not `red`. DGPA's 19:23 update lists no work-or-class suspension.
Nationwide regional scan: North: Wulai, Fuxing, Jianshi, Wufeng, Nanzhuang, and Tai'an return to weather `monitoring`; no new level-one inundation alert, debris-flow or large-scale-landslide red/yellow alert, road interruption, evacuation, shelter activation, suspension, or public-service interruption was found. Central: Heping, Ren'ai, Xinyi, and Alishan return to weather `monitoring`, with no new escalation found. South: the Tainan mountain region; Taoyuan, Namasia, and Maolin in Kaohsiung; and Sandimen, Wutai, Majia, Taiwu, Laiyi, Chunri, Shizi, and Mudan in Pingtung return to weather `monitoring`; Taoyuan separately remains under the South Cross-Island Highway `transport / watch`. East: Datong and Nan'ao in Yilan, Xiulin/Wanrong/Zhuoxi in Hualien, and the listed Taitung Indigenous townships return to weather `monitoring`; Haiduan separately remains under `transport / watch`. The existing formal `red` inside the officially mapped Wanli River channel has not been found formally lifted and remains limited to that mapped channel.
Alert level: ARDSWC currently lists zero red and zero yellow debris-flow alerts and zero red and zero yellow large-scale-landslide alerts. This scan found no Indigenous-area level-one inundation alert, rapid-stream-rise escalation, formal evacuation, shelter activation, transport-wide suspension, major agricultural-loss warning, or other public-service interruption escalation. If the site's overall `red` remains displayed, its only basis is the previously established Forestry and Nature Conservation Agency red alert inside the officially mapped Wanli River channel. August 28 monitoring says the natural dam remains intact, overflow is stable, effects remain confined to the channel, and no formal lifting notice has been found.
Recommended action: Although the heavy/torrential-rain advisories have ended, mountain activity should still follow local weather, stream, and road conditions. Do not enter the Meishankou-Xiangyang section of the South Cross-Island Highway until the Highway Bureau formally reopens it. Do not enter the officially mapped Wanli River channel until its formal red alert is lifted.
Official notices govern.
15:50 Update: Heavy-Rain Advisory Expanded; Torrential-Rain Watch in Hsinchu and Miaoli, Xiulin Mountain-Rain Alert
Information time: August 29, 2026, 15:50.
Official sources: Central Weather Administration, Highway Bureau, Agency of Rural Development and Soil and Water Conservation, Water Resources Agency disaster information service, Directorate-General of Personnel Administration, Hualien Branch of the Forestry and Nature Conservation Agency, and relevant local authorities.
Indigenous areas affected: CWA's 15:15 advisory placed Hsinchu and Miaoli at the torrential-rain level and listed mountain areas of New Taipei and Taoyuan, Taichung and Nantou, Chiayi, Tainan, Kaohsiung, Pingtung, Yilan, Hualien, and Taitung at the heavy-rain level. Jianshi, Wufeng, Nanzhuang, and Tai'an were therefore `watch / torrential rain`; the other affected Indigenous areas were `watch / heavy rain`, not `red`. Severe-thunderstorm messages for Hsinchu/Miaoli and Hualien had expired by this scan, while the Shapodang Creek mountain-rain disaster alert affecting Xiulin remained active through 16:02.
Roads and public services: The Meishankou-Xiangyang section remained closed and was kept at `transport / watch` for Taoyuan and Haiduan. DGPA's afternoon update still listed no work-or-class suspension.
Alert level: ARDSWC debris-flow and large-scale-landslide red/yellow alerts remained at zero. The site-wide `red` was not derived from the rain watches; it remained limited to the officially mapped Wanli River channel.
Recommended action: Indigenous communities under rain watches were advised to reduce nonessential entry into streams, steep slopes, and rockfall-prone roads. During the Xiulin mountain-rain alert, people were advised to leave streams and channels immediately. The South Cross-Island Highway section and the Wanli River channel remained off limits until formal reopening or lifting.
Official notices govern.
12:09 Update: Torrential-Rain Watch for Tainan and Pingtung; Heavy-Rain Watch for Chiayi and Kaohsiung
Information time: August 29, 2026, 12:09.
Official sources: Central Weather Administration, Highway Bureau, Agency of Rural Development and Soil and Water Conservation, Water Resources Agency disaster information service, Directorate-General of Personnel Administration, Hualien Branch of the Forestry and Nature Conservation Agency, and relevant local authorities.
Indigenous areas affected: CWA's 10:25 advisory placed Tainan and Pingtung under possible localized heavy or torrential rain and areas from Chiayi southward under localized heavy rain. Alishan and Kaohsiung Taoyuan/Namasia/Maolin were `watch / heavy rain`; the Tainan mountain region and the listed Pingtung Indigenous townships were `watch / torrential rain`. These were weather watches, not `red`.
Roads and public services: The Meishankou-Xiangyang section had not been found formally reopened, so Taoyuan and Haiduan remained `transport / watch`. DGPA still listed no work-or-class suspension.
Alert level: ARDSWC debris-flow and large-scale-landslide red/yellow alerts remained at zero, with no new level-one inundation, formal evacuation, shelter activation, or major public-service interruption found. The Wanli River `red` remained geographically limited to the officially mapped channel.
Recommended action: Indigenous mountain areas from Chiayi southward were advised to avoid unnecessary travel in stream valleys, steep terrain, and rockfall-risk roads, and to watch for short-duration intense rainfall and rapid stream rises. The South Cross-Island Highway and Wanli River channel restrictions remained in force.
Official notices govern.
03:58 Update: Southern Taiwan Heavy-Rain Advisory Lifted; South Cross-Island Highway Closure and Wanli River Channel Red Remained
Information time: August 29, 2026, 03:58.
Official sources: Central Weather Administration, Highway Bureau, Agency of Rural Development and Soil and Water Conservation, Water Resources Agency disaster information service, Directorate-General of Personnel Administration, Hualien Branch of the Forestry and Nature Conservation Agency, and relevant local authorities.
Indigenous areas affected: The southern heavy-rain advisory issued at 21:30 on August 28 had ended by this scan. The weather watches for the Tainan mountain region, Kaohsiung Taoyuan/Namasia/Maolin, and the listed Pingtung Indigenous townships were lifted and returned to `monitoring`.
Roads and public services: Taoyuan and Haiduan remained `transport / watch` because the South Cross-Island Highway section had not been formally reopened. DGPA listed no work-or-class suspension.
Alert level: ARDSWC red/yellow alerts remained at zero and no new level-one inundation, evacuation, shelter activation, major agricultural-loss warning, or public-service interruption escalation was found. The Wanli River `red` remained limited to the officially mapped channel.
Recommended action: Even after the southern rain advisory ended, mountain travel was to follow local weather and road conditions. The Meishankou-Xiangyang section and the officially mapped Wanli River channel were not to be entered before formal reopening or lifting.

00:02 Update: Southern Taiwan Heavy-Rain Advisory Reissued; South Cross-Island Highway Closure and Wanli River Channel Red Continued
Information time: August 29, 2026, 00:02.
Official sources: Central Weather Administration, Highway Bureau, Agency of Rural Development and Soil and Water Conservation, Water Resources Agency disaster information service, Directorate-General of Personnel Administration, Hualien Branch of the Forestry and Nature Conservation Agency, and relevant local authorities.
Indigenous areas affected: CWA's 21:30 advisory on August 28 listed Tainan, Kaohsiung, and Pingtung under heavy rain. The Tainan mountain region, Kaohsiung Taoyuan/Namasia/Maolin, and the listed Pingtung Indigenous townships were therefore `watch / heavy rain`, not `red`.
Roads and public services: The Meishankou-Xiangyang road section remained `transport / watch` for Taoyuan and Haiduan. The earlier strong-wind watch for Lanyu was no longer active, and DGPA listed no work-or-class suspension.
Alert level: ARDSWC red/yellow alerts remained at zero. No new Indigenous-area level-one inundation, formal evacuation, shelter activation, transport-wide suspension, major agricultural-loss warning, or public-service interruption escalation was found. The Wanli River `red` remained confined to the officially mapped channel.
Recommended action: Indigenous mountain areas in Tainan, Kaohsiung, and Pingtung were advised to avoid unnecessary entry into stream valleys, steep slopes, and rockfall-prone roads and to watch for short-duration heavy rain and rapid stream rises. The South Cross-Island Highway and Wanli River channel restrictions remained in force.
