The unstable weather is expected to last until May 25, as the island is still reeling from precipitation caused by a southwestern flow and a stationary front. The Central Weather Bureau has issued extremely heavy rain warnings for several regions and people who are traveling over the weekend should be cautious. The Central Weather Bureau forecasts the front will gradually move towards the south on May 23, and the rain should ease up a bit.
All of Taiwan experienced rain on May 22 due to the interaction between a stationary front and a southwestern flow. Southern Taiwan saw heavy rain. The accumulated rainfall over a 24-hour period in Pingtung's Chunri Township surpassed 337 millimeters. The Central Weather Bureau issued successive "extremely heavy rain special warnings" that said May 22 is the day when the southwestern flow will be the strongest. Kaohsiung should therefore be prepared for torrential rain, while Pingtung County will see "extremely torrential rain." Today, the only place without a heavy rain warning is Hualien's plains. All other areas are seeing extremely heavy rain, and all are included within the extremely heavy rain special warnings. A strong convective cloud system on the plum rain front is moving towards Taiwan in waves, so the weather is unstable everywhere. We want to remind everyone that several days of consecutive rain have already loosened soil and rocks in mountainous areas, and landslides may occur following today's heavy rain. All of Taiwan saw unstable weather on May 22. The Central Weather Bureau forecasts the front will gradually move towards the south on May 23, and the rain should ease up a bit. However, northern Taiwan will still see cloudy weather while the south will see showers or thunderstorms. Weather analysts also reminded the public that several days of consecutive rain may cause soil and rocks to loosen in mountainous areas, which could in turn lead to natural disasters. It will ease up slightly tomorrow and the day after that, but it hasn't completely stopped yet. That's why people should avoid going to mountainous areas tomorrow and the day after that. The unstable weather is expected to last until May 25. The CWB reminds the public that short but intense showers are often accompanied by strong winds, lighting, and thunder, and people who are traveling should be extra vigilant. Meanwhile, low-lying areas need to be on the alert for flooding. 滯留鋒面持續在台灣上空擺盪，遇上強勁西南氣流，全台有雨，尤其南部地區雨勢最劇烈，屏東縣"春日鄉"24小時累積降雨量，已經超過337毫米，氣象局持續發布"豪雨特報"，提醒週五將是西南氣流最強勁的一天，高雄市要嚴防大豪雨，屏東縣將出現"超大豪雨"。 氣象局簡任技正 伍婉華表示：「其實今天只有在花蓮平地，不是大雨特報的區域，其他各地都有豪雨發生，都是在豪雨特報的區域裡面。梅雨鋒面上旺盛對流雲系，一波一波移向台灣地區，所以各地的天氣相當不穩定。我們要提醒大家，首先在山區的部分，連日的降雨，已經讓山區的土石很鬆軟，所以今天還有這麼強的雨勢下下來，山區可能會有落石坍方、土石流的危險。」 全台天氣非常不穩定，氣象局預計，週六鋒面逐漸南移，降雨會稍微趨緩一些，不過北部仍是陰天，南部地區可能還是會有陣雨或雷雨。氣象專家也提醒，連續降雨山區土石鬆軟，可能釀災。 天氣分析師 吳聖宇表示：「明、後天只是比較緩和，但是還沒說到完全會停下來的程度，所以說, 提醒盡量能夠避免，明、後天到山區活動這個情況。」 不穩定的天氣將持續到下週一，氣象局也提醒民眾，短時強降雨容易伴隨強風雷擊，民眾交通往返要特別留意，而適逢大潮，低窪地須也要嚴防淹水。
