TAIPEI (TVBS News) — A stationary weather front has drifted southward toward the Bashi Channel, triggering scattered rainfall and thunderstorms throughout Taiwan, the Central Weather Administration (CWA, 中央氣象署), Taiwan's national meteorological agency, announced Thursday (June 5). Weather officials warned that regions south of Hsinchu county and mountainous areas in eastern Taiwan's Hualien and Taitung counties face elevated risks of intense, short-duration downpours that could potentially cause flash flooding in vulnerable areas.
Meteorologists reported that Penghu, an island county in the Taiwan Strait, had already received substantial precipitation earlier in the day. The combination of daytime heating and atmospheric instability continues to create favorable conditions for intense rainfall, particularly in areas south of Hsinchu and the mountainous eastern regions of Hualien and Taitung. Weather specialists predict precipitation intensity will diminish by evening hours, though isolated showers remain possible across other parts of the island as the weather system gradually weakens.
As the northeast monsoon loses strength, meteorologists expect an easterly wind flow to usher in milder conditions for northern Taiwan. Daytime high temperatures will likely reach between 27 to 29 degrees Celsius (80.6 to 84.2°F) in northern and eastern regions, while central and southern areas could experience warmer readings of 31 to 32 degrees Celsius (87.8 to 89.6°F). Overnight lows throughout the main island will range from 23 to 25 degrees Celsius (73.4 to 77°F). Taiwan's outlying islands will see varying conditions: Penghu with temperatures between 25 to 28 degrees Celsius (77 to 82.4°F), Kinmen 23 to 28 degrees Celsius (73.4 to 82.4°F), and Matsu 22 to 25 degrees Celsius (71.6 to 77°F), with occasional brief showers expected across these territories.
Emergency management officials urge residents in flood-prone areas to maintain awareness of rapidly changing weather conditions and monitor official CWA updates throughout the day. Travelers to mountainous regions should exercise particular caution due to increased risks of landslides and flash flooding that typically accompany intense, localized downpours during Taiwan's early summer rainy season. ◼
