TAIPEI (TVBS News) — Meteorologist Wu De-romg (吳德榮) forecasted Tuesday (Sept. 2) a slight increase in atmospheric moisture from the south on Wednesday, bringing partly cloudy skies and a modest temperature decline across Taiwan. Wu warned that afternoon conditions could trigger convective developments in mountainous regions, potentially extending to plains with localized thunderstorms accompanied by strong winds, heavy rain, hail, and lightning. The weather expert's predictions signal a shift from recent stable conditions to more volatile atmospheric patterns.
Wu noted that from Thursday (Sept. 4) to Sunday (Sept. 7), Taiwan will experience sunny weather with high temperatures reaching 37 to 38 degrees Celsius (98.6 to 100.4°F) in northern regions. Afternoon thunderstorms or localized showers might develop in mountainous areas, occasionally spreading to nearby plains. Wu predicted increased southern moisture on Sept. 8, creating partly cloudy skies across Taiwan, with northern areas remaining hot while eastern regions and Hengchun Peninsula, Taiwan's southernmost tip, may experience brief showers or thunderstorms.
Wu also highlighted that the European Centre for Medium-Range Weather Forecasts (ECMWF), Europe's premier meteorological modeling center, indicates through models from Sept. 1 and Sept. 4 a tropical disturbance positioned east of the Ryukyu Islands, Japan's southwestern island chain. The disturbance carries a 40% probability of developing into a typhoon, representing a moderate but significant threat to regional weather stability. This development adds another layer of uncertainty to Taiwan's already complex weather patterns as the island enters its peak typhoon season. ◼
