19:46 Update: Heavy-Rain Watch Added for Three Kaohsiung Indigenous Districts; Reservoir Warnings Extended to 21:19

Information time: September 13, 2026, 19:46.

Official sources: 18:12 Central Weather Administration heavy-rain advisory, 18:18 Water Resources Agency Zengwen Reservoir release warning, 18:18 Hushan Reservoir release warning, 18:08 Baoshan Second Reservoir release warning, 16:52 CWA land strong-wind advisory, 09:10 Wanli Creek barrier-lake alert CAP, Agency of Rural Development and Soil and Water Conservation slope-hazard alerts, Directorate General of Highways Highway 7 Daman notice, and Directorate-General of Personnel Administration work/class status.

Affected Indigenous areas and levels: At 18:12, the CWA updated its heavy-rain advisory for Kaohsiung and mountainous Yunlin. The detailed area list includes Taoyuan, Namasia and Maolin districts in Kaohsiung, placing all three under `weather / watch / yellow`, not red, through 23:00. Residents should watch for lightning, strong gusts, slope failures, rockfalls and rapid stream rises. In Yunlin, only Gukeng is listed; the advisory is not expanded to central Indigenous areas or Alishan.

At 18:18, the WRA renewed the red-coded level-one Zengwen and Hushan reservoir release warnings through 21:19. At 18:08, it renewed the level-one Baoshan Second Reservoir release warning through 21:09. Red applies only to officially listed downstream riverbeds and impact corridors. It does not apply to Jianshi, Wufeng, Alishan or another unlisted Indigenous area, and does not mean every part of a listed township is under a blanket red alert.

The Wanli Creek county alert zone remains `access-restriction / watch` through 20:00. Its text prohibits entry around the embankment, riverbed and other designated alert zones; it is not a resident evacuation order and not a red alert for all of Wanrong Township. Lanyu's yellow land strong-wind advisory for September 14 remains `weather / watch / yellow`, not red. The 16:52 detailed area list does not add a Pingtung Indigenous township. Highway 7 at 48.9K in Daman, Fuxing, remains closed under `transport / watch`, not red.

Nationwide assessment:

• North: The Baoshan Second warning is limited to its officially listed downstream area and does not apply to Jianshi or Wufeng. The Highway 7 Daman closure continues. No new threshold-level change was found for Wulai, Nanzhuang or Tai'an.
• Central: The Hushan warning is limited to listed downstream Beigang River areas and does not apply to Alishan. The rain advisory lists only Gukeng in Yunlin. No new threshold-level change was found for Heping, Ren'ai, Xinyi or Alishan.
• South: Taoyuan, Namasia and Maolin are newly under a yellow heavy-rain watch. The Zengwen warning covers listed Tainan mountain areas and Dapu in Chiayi. No new level-one inundation warning, slope-hazard escalation, road interruption or evacuation was found for the covered Pingtung Indigenous areas.
• East: The Wanli Creek access-restriction watch remains effective through 20:00, and Lanyu's yellow wind watch continues. No other threshold-level change was found for Datong, Nan'ao or the covered Hualien and Taitung Indigenous areas.

No level-one inundation warning is active. No new debris-flow or large-scale-landslide red/yellow escalation, Indigenous resident evacuation, shelter opening, school-level closure, transport suspension, major agricultural loss, disaster-caused utility outage or other major public-service disruption was found. At 19:14 on September 13, the DGPA reported no work or class suspensions.

Recommended action: In Taoyuan, Namasia and Maolin, avoid streams, riverbeds and unstable slopes. Stay away from riverbeds in the listed Zengwen, Hushan and Baoshan Second release-warning areas. Do not enter the Wanli Creek county alert zone. In Lanyu, secure outdoor items and check live ferry and flight status. Highway 7 at Daman remains closed. Official real-time notices govern.

16:18 Update: Three Level-One Reservoir Release Warnings Renewed Through 19:19

Information time: September 13, 2026, 16:18.

Official sources: 16:18 Water Resources Agency Zengwen Reservoir release warning, 16:18 Hushan Reservoir release warning, 16:08 Baoshan Second Reservoir release warning, 09:10 Wanli Creek barrier-lake alert CAP, 10:46 Central Weather Administration land strong-wind advisory, Central Weather Administration heavy-rain advisories, Agency of Rural Development and Soil and Water Conservation slope-hazard alerts, Directorate General of Highways Highway 7 Daman notice, and Directorate-General of Personnel Administration work/class status.

Affected Indigenous areas and levels: At 16:18, the Water Resources Agency renewed the red-coded level-one Zengwen and Hushan reservoir release warnings through 19:19. At 16:08, it renewed the red-coded level-one Baoshan Second Reservoir release warning through 19:09. Red applies only to the officially listed downstream riverbeds and impact corridors. It does not apply to Jianshi, Wufeng, Alishan or another unlisted Indigenous area, and does not mean every part of a listed township is under a blanket red alert.

The Wanli Creek county alert zone remains active through 20:00 under `access-restriction / watch`. Its official text prohibits entry around the embankment, riverbed and other designated alert zones; it is not a resident evacuation order and not a red alert for all of Wanrong Township. Lanyu's yellow land strong-wind advisory for September 14 remains `weather / watch / yellow`, not red. Any ferry or flight suspension requires a separate transport-authority announcement.

No heavy- or extremely-heavy-rain advisory and no level-one inundation warning are active. No new debris-flow or large-scale-landslide red/yellow alert escalation was found. Highway 7 at 48.9K in Daman, Fuxing, remains closed under `transport / watch`, not red.

At 16:08 on September 13, the Directorate-General of Personnel Administration reported no work or class suspensions.

Recommended action: Stay away from riverbeds in the listed Zengwen, Hushan and Baoshan Second release-warning areas. Do not enter the Wanli Creek county alert zone. In Lanyu, secure outdoor items and check live ferry and flight status. Highway 7 at Daman remains closed. Official real-time notices govern.

12:02 Update: Wanli Creek Access Zone Renewed; Lanyu Strong-Wind Watch Added

Information time: September 13, 2026, 12:02.

Official sources: 09:10 Wanli Creek barrier-lake alert CAP, 10:46 Central Weather Administration land strong-wind advisory, 10:18 Water Resources Agency Zengwen Reservoir release warning, 10:18 Hushan Reservoir release warning, 10:08 Baoshan Second Reservoir release warning, Central Weather Administration heavy-rain advisories, Agency of Rural Development and Soil and Water Conservation slope-hazard alerts, Directorate General of Highways Highway 7 Daman notice, and Directorate-General of Personnel Administration work/class status.

Affected Indigenous areas and levels: Hualien County renewed the Wanli Creek barrier-lake CAP at 09:10 through 20:00. It says the lake is overflowing steadily but uncertainty remains, and entry is prohibited around the embankment, riverbed and other county-designated alert zones. The website classifies this as `access-restriction / watch`. Although the CAP category is evacuation and shelter, its text does not order residents to evacuate or open shelters. It must not be presented as a resident evacuation or a red alert for all of Wanrong Township.

At 10:46, the Central Weather Administration issued a yellow land strong-wind advisory. With the northeast monsoon strengthening on September 14, Lanyu Township may experience sustained force-6 winds or gusts of force 8 or above. Lanyu is therefore under `weather / watch / yellow`, not red. Secure outdoor items and watch for flying debris, driving hazards and public-transport delays. Any actual flight or ferry suspension requires a separate transport-authority announcement.

At 10:18, the Water Resources Agency renewed the red-coded level-one Zengwen and Hushan reservoir release warnings through 13:18. At 10:08, it renewed the red-coded level-one Baoshan Second Reservoir release warning through 13:08. Red applies only to downstream impact corridors listed in the official CAP messages. It does not apply to Jianshi, Wufeng, Alishan or another unlisted Indigenous area, and does not mean every part of a listed township is under a blanket red alert.

No heavy- or extremely-heavy-rain advisory and no level-one inundation warning are active. No new debris-flow or large-scale-landslide red/yellow alert escalation was found. Highway 7 at 48.9K in Daman, Fuxing, remains closed under `transport / watch`, not red.

Nationwide assessment:

• North: The Baoshan Second warning is limited to its listed downstream areas, while the Highway 7 closure continues. The yellow wind advisory lists coastal areas of Taoyuan, Hsinchu and Miaoli, but not Jianshi, Wufeng, Nanzhuang, Tai'an or Wulai; the alert is not expanded to those Indigenous areas.
• Central: The Hushan warning is limited to listed downstream Beigang River areas and does not apply to Alishan. The yellow wind advisory lists coastal Taichung, not Heping, Ren'ai or Xinyi.
• South: The Zengwen warning covers listed Tainan mountain areas and Dapu in Chiayi. No new level-one inundation warning, slope-hazard escalation, road interruption or evacuation was found for the covered Kaohsiung and Pingtung Indigenous areas.
• East: Lanyu has a new yellow strong-wind watch for September 14. The Wanli Creek county alert zone returns to access-restriction/watch. No other threshold-level change was found for Datong, Nan'ao or the covered Hualien and Taitung Indigenous areas.

No new Indigenous resident evacuation, shelter opening, school-level closure, transport suspension, major agricultural loss, disaster-caused utility outage or other major public-service disruption was found. At 11:59 on September 13, the Directorate-General of Personnel Administration reported no work or class suspensions.

Recommended action: Do not enter the Wanli Creek county alert zone. In Lanyu, secure outdoor items and check live ferry and flight status. Stay away from riverbeds in the listed Zengwen, Hushan and Baoshan Second release-warning areas. Highway 7 at Daman remains closed. Official real-time notices govern.

08:29 Update: Three Level-One Reservoir Release Warnings Continue

Information time: September 13, 2026, 08:29.

Official sources: 08:18 Water Resources Agency Zengwen Reservoir release warning, 08:18 Water Resources Agency Hushan Reservoir release warning, 08:08 Water Resources Agency Baoshan Second Reservoir release warning, Central Weather Administration heavy-rain advisories, Agency of Rural Development and Soil and Water Conservation slope-hazard alerts, Forestry and Nature Conservation Agency barrier-lake monitoring, Directorate General of Highways notice for Highway 7 at Daman, and Directorate-General of Personnel Administration work/class status.

Affected Indigenous areas and levels: At 08:18, the Water Resources Agency renewed the red-coded level-one regulated-release warning for Zengwen Reservoir and the level-one overflow warning for Hushan Reservoir through 11:18. At 08:08, it renewed the red-coded level-one overflow warning for Baoshan Second Reservoir through 11:08. The Zengwen notice lists mountain-area townships in Tainan, including Dongshan, Nansi, Yujing, Zuozhen and Danei, plus Dapu in Chiayi. The Hushan notice lists lowland areas of Yunlin and Chiayi. The Baoshan Second notice lists Baoshan and Emei in Hsinchu County and districts of Hsinchu City.

These red labels are level-one reservoir-release warnings. Action is directed to downstream banks and riverbeds in the officially listed areas. They must not be applied to Jianshi, Wufeng, Alishan or another unlisted Indigenous area, and do not mean every part of a listed township is under a blanket red alert. People near the downstream corridor should stay away from the riverbed.

The Central Weather Administration currently lists no active heavy- or extremely-heavy-rain advisory. Wulai, Datong and Nan'ao remain under `monitoring`. No level-one inundation warning is active. Wanli Creek in Hualien remains under `barrier-lake / monitoring`; this brief does not independently declare the former county alert zone open. Highway 7 at 48.9K in Daman, Fuxing, remains closed under `transport / watch`, not red.

Nationwide assessment:

• North: The Baoshan Second release warning applies only to its officially listed downstream impact area, not Jianshi or Wufeng. The Highway 7 Daman closure continues. No new threshold-level change was found for Wulai, Nanzhuang or Tai'an.
• Central: The Hushan release warning applies only to its officially listed Beigang River downstream area, not Alishan. No new threshold-level change was found for Heping, Ren'ai or Xinyi.
• South: The Zengwen release warning covers listed areas in Tainan's mountain belt and Dapu in Chiayi. No new level-one inundation warning, slope-hazard escalation, road interruption or evacuation was found for the covered Kaohsiung and Pingtung Indigenous areas.
• East: Datong and Nan'ao remain under monitoring; Wanli Creek remains under monitoring. No other threshold-level change was found for the covered Hualien and Taitung Indigenous areas.

No new debris-flow or large-scale-landslide red/yellow alert escalation, Indigenous resident evacuation, shelter opening, transport suspension, school-level closure, major agricultural loss, disaster-caused utility outage or other major public-service disruption was found. At 08:26 on September 13, the Directorate-General of Personnel Administration reported no work or class suspensions.

Recommended action: Stay away from downstream riverbeds in the Zengwen, Hushan and Baoshan Second reservoir release-warning areas and follow live WRA notices. Highway 7 at Daman remains closed. Check current weather and road information before mountain travel. For Wanli Creek access, follow subsequent authority notices. Official real-time notices govern.

04:19 Update: Heavy-Rain Advisory Lifted; Hushan Reservoir Warning Continues

Information time: September 13, 2026, 04:19.

Official sources: 03:42 Central Weather Administration cancellation, 04:18 Water Resources Agency Hushan Reservoir release warning, 00:18 Water Resources Agency Zengwen Reservoir CAP, 00:18 Water Resources Agency Baoshan Second Reservoir CAP, Forestry Agency barrier-lake monitoring, Directorate General of Highways notice for Highway 7 at Daman, and Directorate-General of Personnel Administration work/class status.

Affected Indigenous areas and levels: At 03:42, the Central Weather Administration said rainfall had eased and the likelihood of heavy or extremely heavy rain had decreased, so it cancelled the advisory. The `weather / watch` for Wulai District and Datong and Nan'ao townships has ended and the three areas return to `monitoring`; this is not the cancellation of a red alert. The CWA noted locally heavier rain remained possible over the Hengchun Peninsula before dawn, but no new heavy-rain advisory covered an Indigenous area.

At 04:18, the Water Resources Agency renewed the red-coded level-one Hushan Reservoir release warning through 07:18. It covers listed lowland areas of Yunlin and Chiayi along the downstream Beigang River corridor. Red applies only to that officially listed corridor and must not be applied to Alishan or another Indigenous area. The latest Zengwen and Baoshan Second reservoir CAP messages expired at 03:19 and had not been renewed by 04:19, so they are no longer listed as active release warnings. Whether release operations continue must be checked through live WRA information.

Wanli Creek in Hualien remains under `barrier-lake / monitoring`; this brief does not independently declare the former county alert zone open. Highway 7 at 48.9K in Daman, Fuxing, remains closed under `transport / watch`, not red.

Nationwide assessment:

• North: Wulai's weather watch is lifted, and the Baoshan Second Reservoir CAP expired without renewal. The Highway 7 Daman closure continues. No new threshold-level change was found for Jianshi, Wufeng, Nanzhuang or Tai'an.
• Central: Hushan Reservoir's level-one warning applies only to listed downstream Beigang River areas in Yunlin and Chiayi, not Alishan. No new threshold-level change was found for Heping, Ren'ai or Xinyi.
• South: The Zengwen Reservoir CAP expired without renewal. No new level-one inundation warning, slope-hazard escalation, road interruption or evacuation was found for Tainan's mountain areas or the covered Kaohsiung and Pingtung Indigenous areas.
• East: The weather watch for Datong and Nan'ao is lifted. Wanli Creek remains under monitoring. No other threshold-level change was found for the covered Hualien and Taitung Indigenous areas.

No level-one inundation warning is active. No new debris-flow or large-scale-landslide red/yellow alert escalation, Indigenous resident evacuation, shelter opening, transport suspension, school-level closure, major agricultural loss, disaster-caused utility outage or other major public-service disruption was found. At 03:56 on September 13, the Directorate-General of Personnel Administration reported no work or class suspensions.

Recommended action: Stay away from the Beigang River bed in areas covered by the Hushan Reservoir release warning and follow live WRA notices. Highway 7 at Daman remains closed. Although the rain advisory has been lifted for Datong, Nan'ao and Wulai, check current weather and road information before mountain travel. For Wanli Creek access, follow subsequent authority notices. Official real-time notices govern.

00:11 Update: Yilan Indigenous Heavy-Rain Watch Extended; Dongshan Warning Lifted

Information time: September 13, 2026, 00:11.

Affected Indigenous areas and levels: The CWA's 20:19 update remains valid through 06:00 on September 13. Datong and Nan'ao townships remain `weather / watch / orange`, not `red`. Wulai District remains `weather / watch / yellow`, not `red`. Mountain areas face possible slope failures, rockfalls and rapid stream rises.

The WRA downgraded Dongshan Township from a level-one to a level-two inundation warning, then lifted the warning at 21:47 on September 12. Dongshan remains a nearby road and stream corridor to Nan'ao, but its former inundation level does not apply to Datong or Nan'ao.

At 22:18, the WRA updated red-coded level-one release warnings for Zengwen, Hushan and Baoshan Second reservoirs, valid through 01:18 on September 13. The Zengwen corridor includes Tainan mountain areas such as Dongshan, Nansi, Yujing, Zuozhen and Danei, plus Dapu in Chiayi. Hushan affects listed lowland areas in Yunlin and Chiayi; Baoshan Second affects Baoshan and Emei in Hsinchu County and Hsinchu City. Red applies only to the officially listed downstream release corridors and must not be expanded into a red alert for an Indigenous area or an entire township.

Wanli Creek in Hualien remains under `barrier-lake / monitoring`; this brief does not independently declare the former county alert zone open. Highway 7 at 48.9K in Daman, Fuxing, remains closed under `transport / watch`, not red.

Nationwide assessment:

• North: Wulai remains under yellow heavy-rain watch and the Highway 7 Daman closure continues. The Baoshan Second release warning covers Baoshan, Emei and Hsinchu City, not Jianshi or Wufeng. No new threshold-level change was found for Nanzhuang or Tai'an.
• Central: The Hushan release warning covers listed lowland areas in Yunlin and Chiayi, not Alishan. No new threshold-level change was found for Heping, Ren'ai or Xinyi.
• South: The Zengwen release warning covers parts of Tainan's mountain areas and Dapu; stay away from the riverbed. No new level-one inundation warning, slope-hazard escalation, road interruption or evacuation was found for the covered Kaohsiung and Pingtung Indigenous areas.
• East: Datong and Nan'ao remain under orange heavy-rain watch through 06:00. Dongshan's inundation warning is lifted and does not apply to the two Indigenous townships. Wanli Creek remains under monitoring. No other threshold-level change was found for the covered Hualien and Taitung Indigenous areas.

No new debris-flow or large-scale-landslide red/yellow alert escalation, Indigenous resident evacuation, shelter opening, transport suspension, school-level closure, major agricultural loss, disaster-caused utility outage or other major public-service disruption was found. At 23:35 on September 12, the Directorate-General of Personnel Administration reported no work or class suspensions.

Recommended action: Avoid streams, riverbeds and unstable slopes in Datong, Nan'ao and Wulai. Stay away from downstream riverbeds covered by reservoir-release warnings and follow live WRA notices. Highway 7 at Daman remains closed. For Wanli Creek access, follow subsequent authority notices. Official real-time notices govern.
