Wanli Creek river-zone red alert continues into October 19; nationwide Indigenous-area monitoring

00:27 update

Information time: October 19, 2026, 00:27. The Forestry and Nature Conservation Agency's latest Wanli Creek measurement is current to October 18 at 09:10. The personnel administration page was updated at 00:14, and the Taitung Airport page at 00:28.

Official sources: Forestry and Nature Conservation Agency Hualien Branch's October 18 Wanli Creek update, Public Warning Platform, Central Weather Administration weather advisories, Water Resources Agency disaster information, Agency of Rural Development and Soil and Water Conservation alert list, Directorate-General of Personnel Administration work/class status, and Taitung Airport daily flights.

Affected Indigenous areas and alert levels:

• Wanrong, Hualien—Wanli Creek: The Hualien Branch's October 18 09:10 measurement reports a water elevation of 1,086.12 metres and storage of approximately 5.1404 million cubic metres. The dam remains intact, overflow is stable and downstream effects are confined to the channel, but storage continues to pose risk. The Wanli Creek channel and Hualien County-designated warning zone remain `barrier-lake / red`. Red applies only to the official river-zone boundary; it does not mean all of Wanrong Township or every settlement is red.
• Lanyu air transport: Taitung Airport's page had switched to October 19 by 00:28, but the displayed flight rows still showed the previous day's results. The new day's status had not yet refreshed, so it is marked `transport / monitoring`; this does not establish any October 19 delay, cancellation, suspension or red alert.
• Other Indigenous areas: The Central Weather Administration county table lists no active weather advisory. The slope-hazard system lists zero red or yellow debris-flow alerts and zero red or yellow large-scale-landslide alerts. The personnel administration page updated at 00:14 lists no work/class suspension. No other threshold-level official change was found.

Nationwide assessment:

• North: No official threshold-level heavy-rain, thunderstorm, level-one flood, flash-rise, slope-alert escalation, road closure, evacuation, sheltering, work/class suspension, transport suspension, major agricultural-loss risk or public-service interruption was found for Wulai, Fuxing, Jianshi, Wufeng, Nanzhuang, Tai'an or lowland Indigenous areas; monitoring continues.
• Central: No such threshold-level official change was found for Heping, Ren'ai, Xinyi or Alishan; monitoring continues.
• South: No such threshold-level official change was found for Indigenous areas in mountainous Tainan, Kaohsiung or Pingtung; monitoring continues.
• East: The Wanli Creek channel and designated warning zone remain red. The new day's Lanyu flight status had not yet refreshed and is marked transport / monitoring. No new threshold-level official change was found elsewhere in Yilan, Hualien or Taitung Indigenous areas.

Recommended action: Do not enter the Wanli Creek embankment area, riverbed or designated warning zone. Lanyu travellers should wait for the daily board to refresh and reconfirm service before departure. Follow the latest official notices.
