Wanli Creek river-zone red alert continues; Lanyu flight rollover awaits confirmation

03:31 update

Information time: October 10, 2026, 03:31. The Taitung Airport page labels the current domestic-flight information as updated at 00:18, and the latest DGPA update is timestamped 03:20.

Official sources: Forestry and Nature Conservation Agency update on the Wanli Creek landslide-dammed lake, Taitung Airport daily flights, Central Weather Administration heavy-rain advisory, CWA land strong-wind advisory, Public Warning Platform, Water Resources Agency inundation warnings, Agency of Rural Development and Soil and Water Conservation alert list, and Directorate-General of Personnel Administration work/class status.

Affected Indigenous areas and alert levels:

• Wanrong, Hualien—Wanli Creek: The Wanli Creek river channel and county-designated warning zone remain `barrier-lake / red`. The red level applies only to the official river-zone boundary; it does not mean all of Wanrong Township or every settlement is red. Forestry agency data show that the dam remains intact, water is overflowing steadily and downstream effects are confined to the channel, but stored water remains a risk.
• Lanyu, Taitung: Although the Taitung Airport page is timestamped 00:18 on October 10, its flight rows still retain the previous day's final results. Those rows cannot establish October 10 cancellations or delays. This scan therefore classifies air transport as `transport / monitoring`, not red and not evidence that all of today's flights are cancelled. Passengers should check the airport and airline again after the daily listing completes its rollover.

Nationwide assessment:

• North: No active heavy-rain, land strong-wind or thunderstorm advisory. No level-one inundation alert, flash-rise warning, slope red/yellow alert, road or bridge closure, evacuation, shelter opening, work/class suspension, transport suspension, major agricultural-loss notice or public-service interruption was found. Wulai, Fuxing, Jianshi, Wufeng, Nanzhuang, Tai'an and lowland Indigenous areas remain under monitoring.
• Central: No active heavy-rain, land strong-wind or thunderstorm advisory. No level-one inundation alert, flash-rise warning, slope red/yellow alert, road or bridge closure, evacuation, shelter opening, work/class suspension, transport suspension, major agricultural-loss notice or public-service interruption was found. Heping, Ren'ai, Xinyi and Alishan remain under monitoring.
• South: No active heavy-rain, land strong-wind or thunderstorm advisory. No level-one inundation alert, flash-rise warning, slope red/yellow alert, Indigenous-area road or bridge closure, evacuation, shelter opening, work/class suspension, transport suspension, major agricultural-loss notice or public-service interruption was found. Southern Indigenous areas remain under monitoring.
• East: The Wanli Creek river channel and designated warning zone remain red. Lanyu's daily flight rollover awaits confirmation and is classified as transport monitoring. No other active heavy-rain, land strong-wind or thunderstorm advisory, level-one inundation alert, flash-rise warning, slope red/yellow alert, Indigenous-area road or bridge closure, evacuation, shelter opening, work/class suspension, transport suspension, major agricultural-loss notice or public-service interruption was found. Other eastern Indigenous areas remain under monitoring.

The Water Resources Agency currently shows no inundation warning. The slope-hazard list shows zero red and zero yellow debris-flow alerts and zero red and zero yellow large-scale-landslide alerts. The DGPA's 03:20 update reports no work or class suspension. The Wanli Creek river-zone red alert is issued under the Forestry agency and local-government system and is separate from the slope-hazard alert system.

Recommended action: Do not enter the Wanli Creek embankment area, riverbed or designated warning zone. Lanyu air passengers should recheck the airport's and airline's current-day flight status before departure. Follow the latest official notices.
