Five afternoon Lanyu round trips cancelled; nationwide weather monitoring continues

00:18 Indigenous-area emergency update

Information time: September 18, 2026, 00:18 (Taiwan time).

Official sources: Central Weather Administration land strong-wind advisory, CWA heavy-rain advisory, Public Warning Platform, Water Resources Agency combined warnings, WRA reservoir-release status, 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, Taitung Airport daily flights, and Directorate-General of Personnel Administration.

Affected Indigenous areas and alert levels:

• Strong wind in Miaoli, Taichung and Pingtung: At 21:33 on September 17, the CWA reissued a yellow land strong-wind advisory for officially listed local areas in Miaoli County, Taichung City, Pingtung County and Penghu County through 18:00 on September 18. This is weather / watch / yellow, not red. It is a county-level signal and must not be extended automatically to Nanzhuang, Tai'an, Heping or every Indigenous township in Pingtung. Each community should follow the latest official local detail.
• Rail transport around Pingtung: The Public Warning Platform reports that a freight-train derailment between Pingtung and Xishi led to single-track bidirectional running from 23:04 on September 17, with possible delays. This is transport / monitoring, not a full suspension or red status. Passengers should check the latest Taiwan Railways service information before travel.
• Road in Fuxing, Taoyuan: The Highway 7 bypass at 48.9K in Daman remains limited to controlled one-way passage for small vehicles from 13:00 to 14:00 daily. It does not open during rain or unstable-slope conditions. This remains transport / access-restriction / watch, not a full reopening.
• Water, slope hazards and barrier lakes: The WRA shows no active inundation, river-level or reservoir-release warning. Baoshan Second, Dapu and Hushan reservoirs remain listed as discharging under reservoir-release / monitoring only, with no Indigenous area listed and no red alert. No debris-flow or large-scale-landslide red/yellow escalation was found. Wanli Stream remains at barrier-lake / monitoring, with no active designated alert-zone notice.
• Taitung–Lanyu air service: At 00:18 the Taitung Airport page still showed the September 17 board. The previous day's across-the-board cancellations must not be extended into September 18; today's route remains at transport / monitoring pending the official daily-board update.

Nationwide regional assessment:

• North: Officially listed local areas in Miaoli return to 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 in Fuxing remains subject to time and vehicle controls. No new heavy rain, severe thunderstorm, level-one inundation, official rapid-stream-rise alert, slope escalation, evacuation, shelter, class suspension or Indigenous utility disruption was found.
• Central: Officially listed local areas in Taichung return to yellow wind watch and are treated as a central observation alert. The county signal is not automatically applied to Heping District. No new heavy rain, level-one inundation, Indigenous road or bridge outage, slope escalation, evacuation, shelter, class suspension or public-service change was found.
• South: Officially listed local areas in Pingtung return to yellow wind watch, not red, and the county signal is not automatically applied to every Indigenous township in Pingtung. Single-track bidirectional railway operation between Pingtung and Xishi is a surrounding transport-monitoring item, not a suspension. No new heavy rain, level-one inundation, official rapid-stream-rise alert, slope escalation, evacuation, shelter or major public-service disruption was found.
• East: No heavy-rain or yellow strong-wind signal, level-one inundation or slope escalation is active for the covered Indigenous areas in Yilan, Hualien and Taitung. Wanli Stream remains under monitoring. The September 18 Lanyu flight board had not yet updated, and there was no new official cancellation or suspension notice at 00:18.

At 23:58 on September 17, 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: Secure outdoor objects and watch for transport delays in officially listed wind-watch areas in Miaoli, Taichung and Pingtung. Check current train or Lanyu flight status before travel. Use the Daman bypass only during the announced window and when on-site controllers permit passage. Official real-time notices govern.

Information time: September 18, 2026, 03:44 (Taiwan time).

Affected Indigenous areas and alert levels:

• Taitung–Lanyu air service: The 03:44 Taitung Airport board lists all eight Taitung-to-Lanyu legs and all eight Lanyu-to-Taitung return legs—16 scheduled sectors in total—as on time. The previous day's across-the-board cancellations do not carry over, so the route returns to transport / monitoring. This is the current schedule; actual operations remain subject to the latest airline and airport notices. It is not red.
• Strong wind in Miaoli, Taichung and Pingtung: The yellow weather / watch issued at 21:33 on September 17 remains in effect through 18:00 on September 18. It is not red. The county-level signal covers officially listed local areas and must not be applied automatically to Nanzhuang, Tai'an, Heping or every Indigenous township in Pingtung.
• Rail transport around Pingtung: The earlier single-track bidirectional-running notice between Pingtung and Xishi no longer appears in the Public Warning Platform's active list. That means only that this immediate alert is no longer active; it does not independently confirm that every train is fully back to normal. Passengers should still check Taiwan Railways' latest service information.
• Water, slope hazards and roads: The WRA still shows no active inundation, river-level or reservoir-release warning; Baoshan Second, Dapu and Hushan reservoirs remain listed as discharging under monitoring. No debris-flow or large-scale-landslide red/yellow escalation was found, and Wanli Stream remains at barrier-lake / monitoring.

• South: Officially listed local areas in Pingtung remain under yellow wind watch, without automatically applying the signal to every Indigenous township. The earlier railway alert has left the active-warning list. No heavy rain, level-one inundation, official rapid-stream-rise alert, slope escalation, evacuation, shelter or major public-service disruption was found.
• East: All 16 scheduled Lanyu flight sectors are currently listed as on time, returning transport status to monitoring. No heavy-rain or strong-wind signal is active for the covered Indigenous areas in Yilan, Hualien and Taitung; Wanli Stream remains under monitoring, with no level-one inundation or slope-alert escalation found.

At 03:40 on September 18, 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 recheck the airline and airport board before departure.
