The China Post news staff–The Central Weather Bureau (CWB) forecast yesterday that the first wave of plum rain will arrive around May 3 and 4, with especially heavy rainfall hitting central and southern Taiwan and exceptionally humid days to be common. Southern Taiwan need not worry about water shortages this season, Director of CWB’s Weather Forecast Center Cheng Ming-dean (鄭明典) said. According to estimates from dynamic models, this year’s plum season will bring in more rainfall than usual from the southern seas, and relatively less from along the Chinese coast.

Taiwan, being right at where the two fronts meet, will receive strong rainfall once water vapor from the south shifts north. Central and southern Taiwan could expect the most amount of rain, he said. Once the plum season rain begins, Taiwan will see rainfall on a nearly daily basis, Cheng said, adding that the first wave of plum rain is expected arrive in the first week of May. According to long-term climate statistics, consecutive days of rainfall should officially begin between May 15 and 20, and the maximum amount of rainfall is most likely to occur between the end of May through mid-June.

Heavy rain, accompanied by thunderstorms and strong winds, could be expected when plum rain fronts linger around Taiwan, Cheng said. The director encouraged people to stay indoors during thunderstorms and avoid talking on the phone. Do not hide under trees, he added.

Because the winds generally blow from the south during May and June, there is a greater chance of higher temperatures across Taiwan. The temperature might drop when rain fronts sweep across the island, but once the sun reappears, temperatures increase again. Days of over-30 degrees Celsius temperatures are bound to occur during the plum rain season, Cheng guaranteed.
