Taiwan Braces for Heavy Rain and Potential Flooding as Weather Administration Issues Advisory

Taiwan's Central Weather Administration (CWA) issued a heavy rain advisory on Wednesday, April 24, 2024, warning residents of potential flooding and landslides across the island. The advisory, effective through the night, covers areas north of Changhua, the Nantou region, and the mountainous areas of Hualien.

According to the CWA, the western half and northeastern parts of Taiwan are expected to see sporadic showers and heavy rain until Sunday, with the heaviest rainfall anticipated on Friday, particularly in the central and southern regions. Weather models predict over 130 mm of rain in western and northeast Taiwan from Wednesday to Sunday (April 24-28).

Meteorologists estimate that the heaviest rainfall will occur from Thursday evening to Saturday (April 25-27), with central and southern Taiwan, including mountainous areas, being the most affected. The CWA forecaster, Huang En-hung, stated, "The rainfall will be most significant on Friday, with intermittent showers or thunderstorms expected nationwide. The central and southern parts of the island are at risk for heavy rain or even extremely heavy rain, while the north and northeast can also expect localized heavy rain."

Residents in the affected areas should be aware of potential lightning strikes, strong gusty winds, and prepare for possible flooding in low-lying areas and landslides, falling rocks, and mudslides in mountainous regions. The CWA also warned of low cloud affecting visibility in the early morning on Friday and Saturday in the outlying Matsu islands.

The heavy rainfall has already caused disruptions across the island. In Taipei's Neihu, strong winds toppled a large tree, briefly halting traffic. Widespread flooding was also reported, with the heaviest rainfall recorded on Henglong Mountain in Miaoli, where accumulation reached 160 millimeters.

Why this matters: The heavy rain advisory and potential for flooding and landslides pose significant risks to the safety and well-being of Taiwan's residents. The recent magnitude 7.2 earthquake in Hualien on April 3 has heightened concerns about the stability of mountainous areas, making the public more vulnerable to the dangers associated with heavy rainfall and its consequences.

The CWA forecasts a respite from the rain on Thursday morning, but another front is set to sweep in with even more downpours in the afternoon. Due to the recent earthquakes, authorities strongly advise the public to avoid activities in mountainous areas or disaster zones. The CWA urges residents to be prepared with rain gear and stay informed about weather updates and any evacuation orders that may be issued in response to the developing situation.
