It was still sunny and hot on Sunday with the mercury reaching 38 degrees in Taitung County. But things will change tomorrow when a low pressure system arrives, raising the chances of rain throughout the island. Central and southern regions, as well as southeastern regions will likely see heavy rain in the next three days. The Central Weather Bureau says the precipitation will continue until Thursday.

It was a scorcher of a day in Taipei on Sunday, with parasols dotting the streets. Temperatures throughout the island were high, with Taitung reaching 38 degrees. However the Central Weather Bureau says the weather will be drastically different on Monday.

From this evening to the early morning tomorrow, a low pressure system will be approaching. The wind will be still coming in from a southwesterly direction in the early morning tomorrow. From the early hours of the morning to late in the morning, there’s a good chance for localized heavy showers to occur in the central and southern regions, especially in the coastal areas.

This weather radar shows a high pressure system over the Pacific that is stretching westward. Meanwhile a low pressure system is moving near Taiwan and bringing in moisture. From Monday to Wednesday, the chances of rain will be high with the possibility of brief showers or thundershowers throughout the island. Central and southern regions, southeastern regions, as well as mountainous regions should watch out for brief torrential rain, lasting until Thursday.

From Monday to Wednesday, the rainfall will be most pronounced, and there will be brief and heavy rainfall in various places, especially in the central and southern regions and the southeastern regions, and other mountainous areas. From Monday to Wednesday, there will be a higher chance of localized heavy rain.

The low pressure system on Friday will leave Taiwan, dispersing moisture in the air. However, the public is still advised to watch out for afternoon thundershowers in mountainous regions.

低壓帶影響週一變天!南台灣留意局部大兩

2022-07-31

來關心周末天氣,今天各地還是高溫炎熱,花蓮縣更熱到38度,不過受到低壓帶影響,明天將開始變天,各地都會出現陣雨或雷雨,而中南部、東南部則要留意局部大雨,兩勢要到周四才會趨緩。

一早台北街頭艷陽高照,行人紛紛撐傘遮陽,周日各地氣溫依舊炎熱,台東出現38度高溫,氣象局預報,周一將開始變天。

“今天晚上到明天清晨的話,低壓帶在接近,那風向在明天清晨,還是比較偏西南風為主,明天清晨的話,清晨到上午這段時間,在中南部地區可能還是會有局部大雨發生的機率,尤其是沿海地區這邊,機率上相對來說會比較特別的高一點”

從雷達迴波圖來看,太平洋高壓勢力往西延伸,低壓帶水氣帶往台灣靠,周一到周三天氣都不穩定,各地有短暫陣雨或雷雨,中南部、東南部和各地山區要注意短延時強降雨,雨勢將持續到周四。

“週一到週三這三天的話,算是降雨最明顯的一個時段,各地都容易會有短延時強降雨的出現,特別是在中南部還有東南部地區,跟其他的山區,在週一到週三這段時間,會有局部大雨發生的一個機率”

周五隨著低壓帶遠離,水氣減少,天氣轉為穩定,不過山區仍有午後雷陣雨,民眾得多加留意。
