Rains to sweep Taiwan from Thursday

2023-08-07

Turning to the weather. More rains are in store for Taiwan as southwesterly winds bear down and bring in moisture. Starting Thursday, showers are expected islandwide. Forecasters warn of catastrophic rainfall in central and southern Taiwan, persisting unabated until Saturday.

Southwesterly winds have brought soaring temps to leeward parts of the north and East Coast, where highs exceeded 35 degrees on Monday. On the windward side of mountainous areas in the south, downpours have lasted for days.

The weather will be quite unstable in the coming week. From Monday through Wednesday, keep an eye out for heavy rains in central and southern Taiwan. Humidity levels will be even higher as we enter Thursday and Friday. There will be a chance of localized heavy rainfall all along the west coast.

As southwesterly winds sweep in moisture, the weather will be volatile in the coming days. Through to Wednesday, there will be a chance of brief showers and localized heavy rains in central and southern Taiwan. But the intensity and scope of the rains will significantly shrink as Typhoon Khanun moves farther away. Officials say they will use the next few days to repair mountain roads cut off by the storm. That’s because come Thursday, rains are expected to strike islandwide. Temperatures may cool slightly in the north and east. In the central and southern regions, extreme rainfall is possible not only in the mountains but the flatlands as well. This round of showers should continue unabated until Saturday.

It is located some 3,000 kilometers east-southeast of Taiwan. This tropical depression could gradually develop into a tropical storm. There’s a good chance it will become a tropical storm by Tuesday. But looking at its trajectory, it should gradually advance toward the eastern seas of Japan.

Tropical Storm Lan, the seventh one of the year, is likely to form by Tuesday. It is expected to track northward and have little impact on Taiwan. Meanwhile Hurricane Dora is expected to reach the western Pacific by Saturday, becoming the eighth storm of the year. Experts say that during typhoon season, one storm a week is standard and no cause for panic, although precautions should still be taken.

週四水氣高峰全台有雨颱風"蘭恩"最快明生成

2023-08-07

西南風帶來豐沛水氣，持續影響台灣。位在迎風面的中南部，這兩天雨勢、雨區變小，搶通聯外道路得盡快，因為氣象局表示，週四開始，全台有雨，甚至不排除致災性大雨可能，到週六雨勢才會趨緩。不過，這兩天北部、東半部，出現35度以上高溫。

西南氣流發威，背風面桃園以北、東半部亮起高溫燈號，出現局部35度以上高溫。迎風面南部山區，則是連日大雨。

“未來一週的話這段時間，天氣相當不穩定，在今天(週一)一直到星期三，包括中南部可能要特別留意，雨勢會比較大，到了星期四、星期五水氣又更多，西半部可能會有局部性大雨發生。”

西南風帶來豐沛水氣，天氣不穩定，週三前，中南部還是有短暫陣雨、局部大雨機率，但雨勢相較先前，隨著卡努遠離，強度、範圍減少不小。山區道路中斷，拼搶通，得把握這幾天。因為週四開始，全台都有雨，北部、東半部稍稍降溫，但中南部雨區，擴展到平地，甚至不排除致災性大雨可能。這波雨勢，得到週六，才會逐漸減弱。

“台灣的東南東方大概3千公里左右的位置，未來的話，這個熱帶性低氣壓，有逐漸發展成颱風的可能，預計明天(週二)發展為颱風的機率是高的，不過路徑上面看起來，應該是逐漸地往日本東方海面前進。”

週二七號颱蘭恩很可能生成，但預估路徑偏北，對台灣影響不大。至於熱帶颶風朵拉，週六可能來到西太平洋，成為八號颱。進入颱風季，專家就說，一週一颱都是正常，不必恐慌，但也不能掉以輕心。
