Taiwan braces for most intense plum rain season, experts warn of disaster-causing downpours

Taiwan is bracing for its most intense and prolonged rainfall of the year as a plum rain front and southwest monsoon converge next week. Weather experts predict this will mark the "peak plum rain season," bringing the most significant downpour since the season began.

The "Taiwan Typhoon Forum | Weather Express" noted that while Tropical Depression 91W is moving away, it plays a crucial role in opening a path for the southwest monsoon. As this monsoon strengthens and the plum rain front approaches, Taiwan can expect continuous rain from Monday to Sunday. The central and southern regions, being on the windward side, will likely experience longer periods of rain. The forum cautioned that severe, localized downpours could occur if thunderstorms develop intensely, urging the public to prepare.

This will be the most significant and prolonged rainfall of this year's plum rain season.

Meteorologist Wu Der-rong, an associate professor at National Central University's Department of Atmospheric Sciences, confirmed the unstable weather conditions for the next two days with isolated showers and potential afternoon thunderstorms. He highlighted that from Monday to the following Sunday, the fifth stationary front of the plum rain season will hover around Taiwan. This period, combined with the prevailing southwest monsoon, signifies a "peak plum rain season." He warned of "severe weather" including lightning, strong winds, and sudden heavy rainfall, along with the threat of "disaster-causing rainfall." He advised everyone to pay close attention to weather advisories and prepare for disaster prevention.

Regarding the duration of this "peak plum rain season," current forecasts from European and American models suggest it could last until at least the following Monday. While specific patterns may vary, the end of the heavy rainfall is not yet in sight. However, forecasts beyond 10 days carry significant uncertainty, and further observation is needed. The public should be mentally prepared for potentially frustratingly wet conditions until around June 17th, when the Pacific high-pressure system is expected to strengthen, signaling a shift towards mid-summer.

Everyone should be especially vigilant about weather advisories from the CWA and prepare for disaster prevention early.
