Another plum rain front is on its way. It will close in starting this Friday, bringing rains that intensify over the weekend. All parts of Taiwan could be in for extremely heavy rain. Although the front will head eastward next week, it will be followed by a low-pressure zone that ushers in another wave of rain. Let’s hear from a forecaster.

As the front makes a gradual approach, humidity levels are also gradually rising, causing weather conditions islandwide to become increasingly unstable. Rainfall is expected nationwide, especially in the north and northeast. By June 10 and 11, which is the weekend, the front will be closest to Taiwan. After June 12, the front in the north of Taiwan will gradually weaken as Typhoon Guchol tracks north. After June 12, Taiwan will mainly be under the influence of a low-pressure zone, with greater humidity brought by a cloud system from southern China. Toward the end this will likely lead to rains, including heavy rains.
Forecasters say a low-pressure zone will approach starting Sunday, bringing abundant moisture. If that’s combined with strong southwesterly winds, there could be consecutive days of rainfall – enough to replenish many dry reservoirs. But the forecaster warns that the heavy rains could also cause natural disasters in the south and western half of the island.
梅雨鋒面又要來了。週五開始接近,全台天氣趨於不穩定,加上週末兩天鋒面最靠近,雨區擴大,雨勢也加大,各地都得嚴防豪雨。下週雖然鋒面東移,但隨之而來的是,今年的第三號颱風谷超,雖然對台灣沒有直接衝擊,但受到低壓帶影響,和台灣南方水氣增加,又將帶來一波雨勢。

“鋒面逐漸在靠近台灣附近,水氣也慢慢變多,各地天氣會變得越來越不穩定,各地都有降雨的狀況,尤其是北部和東北部地區,到了10號,11號,也就是周末兩天,鋒面是離我們台灣最近的,到12號之後,鋒面因為受到谷超颱風慢慢北移的影響,在台灣附近北方的這個鋒面是有逐漸在減弱的狀況,12號之後主要是以低壓帶的影響機會是比較大一點點的,到後期南方水氣都是比較多,可能後面比較容易有強降雨或是降雨情況出現”
氣象專家彭啟明也在粉專分析,周日開始西南季風環境下的低壓帶接近,水氣多,如配合旺盛西南風,將有持續性的數日連續降雨,雨量足以把好幾個月的缺水一周內補完,對南部或西半部都會是相當大的降雨壓力,也是容易致災的天氣類型。
