Weather Administration Predicts Normal to Slightly Less Rainfall for Plum Rain Season, Advises Caution for Short-Duration Heavy Downpours
Taiwan's Central Weather Administration forecasts that the average temperature for this year's plum rain season (May-June) will be normal to slightly higher, while rainfall will be normal to slightly less. However, in recent years, rainfall has tended to be concentrated, and the frequency of short-duration heavy rainfall events has significantly increased, requiring caution.

(Central News Agency reporter Zhang Xiongfeng Taipei 28th news) The Central Weather Administration predicts that for this year's plum rain season in May and June, there is a higher chance for average temperatures to be normal to slightly higher, and for rainfall to be normal to slightly less. In recent years, the plum rain season has shown a trend of rainfall periods becoming more concentrated, and the frequency of short-duration heavy rainfall events has significantly increased.
The Central Weather Administration held a press conference today on the 'Plum Rain Season Outlook'.
Huang Chun-hsi, Director of the Weather Forecast Center of the Central Weather Administration, stated that the main hot spots for plum rain season rainfall are in the mountainous areas of central and southern Taiwan. From the rainfall distribution in Taipei, Taichung, Kaohsiung, and Hualien, the western half experiences more significant rainfall during the plum rain and typhoon seasons. From mid-May to mid-June, rainfall in the southern region will be even more significant during periods of strengthened southwest winds, possibly even surpassing typhoon rainfall.
Huang Chun-hsi pointed out that the El Niño phenomenon is predicted to continue developing from May to July and even into autumn, with an expectation to enter the El Niño state after autumn.
However, Huang Chun-hsi explained that El Niño does not significantly affect Taiwan's plum rain season, and its impact on subsequent typhoons needs to be observed. Statistics from 1951 to the present show that the plum rain season has no fixed pattern, with a maximum of 891.1 millimeters in 2012 and a minimum of 193.4 millimeters in 1980.
Huang Chun-hsi mentioned that since May and June are Taiwan's plum rain season, fronts starting in May will be defined as plum rain fronts. The plum rain index is expected to be established from late May to early June, which may then bring more significant rainfall.
Huang Chun-hsi further explained that for this year's plum rain season, average temperatures across various regions are more likely to be normal to slightly higher, and rainfall normal to slightly less. In recent years, although the total rainfall during the plum rain season has not significantly increased or decreased, rainfall periods have become more concentrated, and the frequency of short-duration heavy rainfall events has significantly increased.
Huang Chun-hsi reminded that severe convective weather such as torrential rain, lightning, and strong gusts may occur during the plum rain season. Caution should be exercised to prevent waterlogging and landslides. Rainfall during the plum rain season varies greatly, and forecast uncertainty is high, so he still urged to cherish water resources. (Editor: Zhang Mingkun) 1150428
