Taiwan has recently concluded its wettest plum rain season in over a decade, witnessing unprecedented rainfall levels across the nation. The Central Weather Administration reports that from May to June, the island received an average of 609.9 millimeters of rain, significantly surpassing the historical norm of 440.7 millimeters. This increase in precipitation was largely due to persistent weather fronts, robust southwesterly winds, and the remnants of a tropical storm.
The southern part of Taiwan was particularly inundated, with areas experiencing between 400 and 800 millimeters of rain in just the first half of June. Notably, Pingtung County saw nearly 1,000 millimeters of rainfall within three days. Meanwhile, Taipei set a new record for June, receiving 870.5 millimeters of rain, the highest monthly total recorded since weather monitoring began in the city in 1897.
As the typhoon season approaches, starting officially on July 1, Taiwanese weather officials anticipate temperatures to hover around normal to above-average levels through September. Rainfall is expected to align with typical seasonal patterns, but the forecast includes the potential for three to five tropical storms or typhoons to approach the region in the latter half of the year.
The development of El Niño conditions in the Pacific Ocean could play a significant role in shaping the intensity of these storms. With warmer ocean waters, there is a higher likelihood that tropical storms will have more time to strengthen before nearing Taiwan. In response to these potential threats, authorities are implementing new coastal wave warning systems aimed at enhancing public safety during extreme weather conditions.
