Haiduan Xiangyang-Lidao Section to Close Preemptively at 18:00; Heping Highway 7A Blockage Remains on Watch
Original Chinese title: 海端向陽至利稻18:00預警封閉：列transport / watch；和平環山台7甲阻斷持續
At 15:21 on August 31, the Highway Bureau announced that Provincial Highway 20 from 149K+110 to 171K+500, Xiangyang to Lidao in Taitung's Haiduan Township, is scheduled for preemptive closure at 18:00 because of repeated rockfalls and unstable saturated slopes. Haiduan is transport / watch, not red. The fallen-tree blockage at Highway 7A 61K in Heping remains listed without an official reopening notice. CWA currently shows no active heavy/torrential-rain advisory or severe-thunderstorm message, while debris-flow and large-scale-landslide red/yellow alerts are all zero.

03:52 Update: Fallen Tree Blocks Both Directions of Highway 7A at 61K in Huanshan, Heping; Pingtung and Taitung Heavy-Rain Watch Cleared
Information time: August 31, 2026, 03:52.
Official sources: Highway Bureau; Central Weather Administration; Water Resources Agency disaster information service; Agency of Rural Development and Soil and Water Conservation debris-flow and large-scale-landslide disaster information service; Forestry and Nature Conservation Agency; Directorate-General of Personnel Administration; and relevant local-government and road-authority notices.
Indigenous areas affected: The Highway Bureau's August 31 provincial-highway real-time information reports a fallen tree at 61K on Provincial Highway 7A in Huanshan. The tree occupies all lanes and blocks the road in both directions. Huanshan is in Taichung's Heping District, so Heping is `transport / watch`, not `red`. The road should not be treated as cleared until the Highway Bureau issues a reopening update. Separately, Provincial Highway 20 temporary route 105, 0K-44K from Meishankou to Xiangyang, remains closed on August 31 under the existing Highway Bureau notice, so Kaohsiung Taoyuan and Taitung Haiduan remain `transport / watch`.
Weather change: CWA's heavy/torrential-rain advisory page currently shows no active county advisory. The Pingtung and Taitung `weather / watch` issued at 19:20 on August 30 is therefore no longer active. Sandimen, Wutai, Majia, Taiwu, Laiyi, Chunri, Shizi, and Mudan in Pingtung, and Beinan, Yanping, Haiduan, Daren, Jinfeng, Taimali, Dawu, and Lanyu in Taitung, return to weather `monitoring`. Haiduan remains under a separate `transport / watch` because of the South Cross-Island Highway control; that transport watch must not be mislabeled as a red weather alert.
Nationwide regional scan: North: Wulai, Fuxing, Jianshi, Wufeng, Nanzhuang, and Tai'an remain `monitoring`; no new heavy-rain warning, severe-thunderstorm alert, level-one inundation alert, slope-disaster escalation, Indigenous-area road interruption, evacuation, shelter activation, work/class suspension, or major public-service interruption was identified. Central: Heping is `transport / watch` because the fallen tree at Highway 7A 61K in Huanshan blocks both directions. Ren'ai, Xinyi, and Alishan remain `monitoring`, with no new disaster-related road interruption or other threshold-level official change identified. South: the Tainan mountain region, Kaohsiung Namasia/Maolin, and Pingtung's listed Indigenous townships are on weather `monitoring`; Kaohsiung Taoyuan remains `transport / watch` because Meishankou-Xiangyang remains closed on August 31. East: Datong/Nan'ao in Yilan, Xiulin/Wanrong/Zhuoxi in Hualien, and the listed Taitung Indigenous areas remain on weather `monitoring`; Haiduan additionally remains `transport / watch`. Wanli River remains `monitoring` under the latest Forestry monitoring and must not be mislabeled `red`.
Other alert assessment: This scan found no new level-one inundation alert, debris-flow or large-scale-landslide red/yellow alert escalation, rapid stream rise, formal evacuation, shelter activation, major agricultural-loss alert, system-wide transport suspension, or major water/power/public-service interruption affecting the listed Indigenous areas. The Directorate-General of Personnel Administration's August 31 update at 03:32 lists class suspensions only at schools in Kaohsiung's Gushan District; those are not Indigenous-area work/class suspensions and must not be attributed to Taoyuan, Namasia, or Maolin.
Alert level: The site's overall level remains `watch` because of the new two-way Highway 7A blockage in Heping and the continuing Taoyuan/Haiduan South Cross-Island Highway controls. No monitoring or watch condition is labeled `red`. The Pingtung and Taitung heavy-rain `weather / watch` has cleared.
Recommended action: Road users in Heping's Huanshan area should avoid the blocked Highway 7A 61K section and follow Highway Bureau traffic-control and reopening notices. Taoyuan and Haiduan road users should not enter the controlled Meishankou-Xiangyang section. Other Indigenous areas should continue monitoring official weather, road, stream, and slope updates. Any later severe thunderstorm, level-one inundation alert, slope-disaster escalation, road interruption, evacuation, shelter activation, work/class suspension, or public-service interruption should be handled according to official updates.
16:09 Update: Xiangyang-Lidao in Haiduan Scheduled for Preemptive Closure at 18:00; Heping Highway 7A Blockage Remains on Watch
Information time: August 31, 2026, 16:09.
Official sources: Highway Bureau; Central Weather Administration; Water Resources Agency disaster information service; Agency of Rural Development and Soil and Water Conservation debris-flow and large-scale-landslide disaster information service; Forestry and Nature Conservation Agency; Directorate-General of Personnel Administration; and relevant local-government and road-authority notices.
Indigenous areas affected: At 15:21, the Highway Bureau announced that recent mountain rainfall and the possibility of further heavy rainfall have left Provincial Highway 20 from 149K+110 to 171K+500, Xiangyang to Lidao in Taitung's Haiduan Township, at elevated risk. The 170K+400 Lidao section has recorded rockfalls for three consecutive days, and saturated slopes are unstable. The Highway Bureau plans to implement a preemptive closure from 18:00 on August 31 and reopen only after weather and road-safety inspections permit. Haiduan therefore remains and is strengthened as `transport / watch`, not `red`. Provincial Highway 20 temporary route 105 from Meishankou to Xiangyang also remains closed on August 31, so Kaohsiung Taoyuan remains `transport / watch`. In Taichung Heping District, the fallen-tree event at Highway 7A 61K in Huanshan is still listed on the Highway Bureau real-time page, and no formal reopening notice was found in this scan; Heping therefore remains `transport / watch`.
Nationwide regional scan: North: Wulai, Fuxing, Jianshi, Wufeng, Nanzhuang, and Tai'an remain `monitoring`. CWA currently shows no active heavy/torrential-rain advisory or severe-thunderstorm message, and no new level-one inundation alert, slope-disaster escalation, road interruption, evacuation, shelter activation, work/class suspension, or major public-service interruption was identified. Central: Heping remains `transport / watch` because Highway 7A 61K in Huanshan is still blocked; Ren'ai, Xinyi, and Alishan remain `monitoring`. South: the Tainan mountain region, Kaohsiung Namasia/Maolin, and Pingtung Sandimen/Wutai/Majia/Taiwu/Laiyi/Chunri/Shizi/Mudan have no newly identified heavy-rain advisory, severe-thunderstorm message, level-one inundation alert, slope-disaster escalation, evacuation, shelter activation, or major Indigenous-area public-service interruption. Kaohsiung Taoyuan remains `transport / watch` because Meishankou-Xiangyang remains closed. The Water Resources Agency currently lists a level-two river-water alert at the Koushe-Fubang Bridge in Gaoshu Township, Pingtung; this is a water-level level-two alert, not a level-one inundation alert, so it is treated only as water-condition observation and is not labeled `red`. East: Datong/Nan'ao in Yilan, Xiulin/Wanrong/Zhuoxi in Hualien, and Beinan/Yanping/Daren/Jinfeng/Taimali/Dawu/Lanyu in Taitung remain `monitoring`; Haiduan is `transport / watch` because Xiangyang-Lidao is scheduled for preemptive closure at 18:00 and the existing South Cross-Island Highway control remains in effect. Wanli River remains `monitoring` under the existing Forestry monitoring and must not be mislabeled `red`.
Slope, water, and work/class status: The Agency of Rural Development and Soil and Water Conservation currently lists zero debris-flow red alerts, zero debris-flow yellow alerts, zero large-scale-landslide red alerts, and zero large-scale-landslide yellow alerts. CWA's heavy/torrential-rain advisory page currently shows no active county level, and its severe-thunderstorm page shows no active event. The Directorate-General of Personnel Administration's 15:38 update still lists class suspensions only at Shoushan Junior High School, Shoushan Elementary School, and its affiliated kindergarten in Kaohsiung's Gushan District; these are not work/class suspensions in Taoyuan, Namasia, Maolin, or other Indigenous areas.
Alert level: The site's overall level remains `watch`. Heping is `transport / watch` for the road blockage; Taoyuan is `transport / watch` for the Meishankou-Xiangyang control; Haiduan is `transport / watch` for the scheduled 18:00 Xiangyang-Lidao preemptive closure and the existing South Cross-Island Highway control. No official basis was found to label any of these monitoring or transport conditions `red`.
Recommended action: Road users in Haiduan, Xiangyang, Lidao, and along the South Cross-Island Highway should complete any essential travel before 18:00 and must not enter Provincial Highway 20 from 149K+110 to 171K+500 after the preemptive closure begins; follow the Highway Bureau's latest reopening notice. Road users in Heping's Huanshan area should continue avoiding Highway 7A 61K, while Taoyuan road users should not enter the Meishankou-Xiangyang controlled section. Other Indigenous areas should continue monitoring official rainfall, water, slope, and road notices.
Official notices govern.
