All Lanyu flights currently on time; yellow wind watch continues in Miaoli and Taichung

04:03 Indigenous-area emergency update

Information time: September 20, 2026, 04:03 (Taiwan time).

Official sources: Taitung Airport daily flights, Central Weather Administration land strong-wind advisory, CWA heavy-rain advisory, Public Warning Platform, Water Resources Agency combined warnings, Agency of Rural Development and Soil and Water Conservation slope-hazard alerts, Forestry and Nature Conservation Agency barrier-lake monitoring, Highway Bureau Daman bypass control plan, and Directorate-General of Personnel Administration.

Affected Indigenous areas and alert levels:

• Taitung–Lanyu air service: At 04:03, all eight round trips—7501/7502, 7503/7504, 7505/7506, 7515/7516, 7507/7508, 7517/7518, 7509/7510 and 7511/7512—were listed as on time, totalling 16 sectors. The previous day's cancellation status does not carry over, so the route shifts to transport / monitoring. Actual operations remain subject to the latest airline and airport notices.
• Strong wind in Miaoli and Taichung: The CWA's 22:23 September 19 update keeps officially listed local areas in Miaoli County, Taichung City and Penghu County under weather / watch / yellow through 17:00 on September 20. This is not red. The county-level signal must not be applied automatically to Nanzhuang, Tai'an or Heping.
• Water and slope hazards: The Public Warning Platform lists free overflow at Baoshan Second and Hushan reservoirs with “minor” severity under reservoir-release / monitoring. The officially listed rivers and administrative areas do not include an Indigenous area; this is not a level-one inundation warning or red alert. No active inundation or river-level warning and no debris-flow or large-scale-landslide red/yellow escalation was found.
• Wanli Stream and roads: Wanli Stream remains at barrier-lake / monitoring; no reopening is inferred without an explicit competent-authority notice. The Daman bypass in Fuxing, Taoyuan remains limited to controlled small-vehicle passage from 13:00 to 14:00 daily under access-restriction / watch.

Nationwide regional assessment:

• North: Officially listed local areas in Miaoli remain under yellow wind watch and are treated as a northern observation alert; the county signal is not automatically applied to Nanzhuang or Tai'an. The Daman bypass remains time-restricted. No heavy rain, severe thunderstorm, level-one inundation, official rapid-stream-rise alert, slope escalation, evacuation, shelter, class suspension or new public-service disruption was found.
• Central: Officially listed local areas in Taichung remain under yellow wind watch and are treated as a central observation alert; the county signal is not automatically applied to Heping. Ren'ai, Xinyi and Alishan remain at weather monitoring. No heavy rain, level-one inundation, Indigenous road or bridge outage, slope escalation, evacuation, shelter, class suspension or public-service change was found.
• South: No heavy-rain, severe-thunderstorm or Indigenous-area strong-wind signal is active. No level-one inundation, official rapid-stream-rise alert, slope escalation, evacuation, shelter, transport suspension or major public-service disruption was found.
• East: All eight Lanyu round trips are currently listed as on time, placing the route at transport monitoring. Wanli Stream remains at barrier-lake monitoring. No heavy-rain or strong-wind signal is active for other covered Indigenous areas in Yilan, Hualien and Taitung, and no level-one inundation or slope-alert escalation was found.

At 03:56 on September 20, the DGPA still reported no work or class suspensions. No resident evacuation, shelter activation, school-level closure, major agricultural-loss warning or new major Indigenous public-service disruption was found.

Recommended action: Lanyu passengers should still check the latest airline and airport status before departure. Secure outdoor objects in officially listed wind-watch areas in Miaoli and Taichung. Do not enter the Wanli Stream riverbed or embankment area without an official reopening notice. Use the Daman bypass only during the announced window and when on-site controllers permit passage. Official real-time notices govern.
