中央大學大氣系兼任副教授吳德榮今在「氣象應用推廣基金會」專欄以「今明仍有強對流 下週脫離不穩定」為題撰文指出,今日至週日(4至6日)北部及東半部有局部短暫雨,午後各地區有局部對流發展的機率,應注意其所伴隨的雷擊、強風、瞬間強降雨。
氣象署表示,第23號輕度颱風科羅旺,下週二(8日)前都在琉球附近海域活動,對台灣天氣沒有直接影響。
氣象署提醒,東南部(含蘭嶼、綠島)沿海有長浪發生的機率,前往海邊活動請注意安全。
空氣品質方面,根據環境部空氣品質預報資訊顯示:今日低壓帶影響,全台受降雨洗除作用影響,擴散條件佳,空氣品質多為良好等級;竹苗、中部、雲嘉南、宜蘭、花東空品區及金門、澎湖為「良好」等級;北部、高屏空品區及馬祖為「普通」等級。
未來天氣方面,週六仍處低壓帶環境,天氣不穩定,易有短延時強降雨;受偏北風影響,北部及宜蘭地區有短暫陣雨,其他地區亦有局部短暫陣雨,且有局部較大雨勢,其中北部及宜蘭地區有局部大雨發生的機率。
週日低壓帶內偏北風影響,北部及宜蘭地區有局部短暫陣雨,其他地區為多雲,有局部短暫雷陣雨,午後山區易有局部較大雨勢。
下週一至下週四環境轉偏北風、水氣減,天氣漸穩定。下週一至二大台北及宜蘭地區仍有局部短暫陣雨,其他地區則為多雲到晴,午後南部地區及其他山區有局部短暫陣雨。下週三至下週四北部及東半部地區有局部短暫陣雨,其他地區為多雲到晴,午後有局部短暫陣雨。
下週五至下下週一台灣附近為偏北風至東北風,北部、東半部有局部短暫陣雨,其他地區為多雲,午後中部山區及南部地區有局部短暫雷陣雨。

Affected by the outer circulation and low-pressure belt of Typhoon Korowang, heavy rainfall occurred in the northern and north coast areas. The rainfall in Wanli District exceeded 150 mm in three hours. Roads in Keelung City were seriously flooded. Eight schools in New Taipei City were suspended and were evacuated as a precaution. The underground parking lot of Taipei Nangang Station was flooded due to drainage failure. The Meteorological Administration forecast that the rain will gradually slow down and become drier next Monday and Tuesday. The northeast monsoon will strengthen next Wednesday but the cooling will not be obvious.

Jia Xingxing, director of Taiwan Integrated Disaster Prevention Engineering Technology Consulting Company, said that due to the influence of the outer circulation of Typhoon Korovang and the intensification of Tropical Disturbance 97W into Typhoon Dujuan, the weather will take a major turn next Sunday (9/6). There will be locally heavy rains in the north of Tainan, while the rainfall in the south will slow down. He also reminded tourists traveling to Japan to pay attention to strong winds and rainfall in Japan's Ryukyu Islands and Kyushu Shikoku.

The Central Meteorological Observatory issued a yellow typhoon warning and a yellow rainstorm warning at 6:00 on September 3. Typhoon "Shadr" will land on the coast from Zhangpu to Dongshan, Fujian, and "Korowang" will move into the East China Sea. Guangdong, Fujian, Jiangxi, Hunan, Taiwan and other places will experience heavy to heavy rains and local heavy rains.
Affected by typhoons "Shadr" and "Korowang", winds increased along the coasts of Guangdong, Fujian and other places and in the South China Sea and East China Sea. Affected by typhoon "Shadr" and the monsoon trough, heavy rainfall occurred in Zhejiang, Fujian, Jiangxi, Guangdong and other places, accompanied by local thunderstorms and strong winds and other strong convective weather. The Central Meteorological Observatory continued to issue typhoon blue warnings and heavy rain yellow warnings.

The Meteorological Administration predicts that due to the influence of low pressure and southwesterly winds on Tuesday, short-term heavy rainfall is likely to occur in the central, southern and southeastern areas, and locally heavy rainfall will occur in other areas. TD-20 will approach the border of Guangdong and Fujian from Tuesday to Thursday and make landfall. Although it will not directly hit Taiwan, its easterly wind will bring showers or thunderstorms and heavy rain. TD-20 will move westward and away on Friday and Saturday, and the weather will become stable after the northeasterly wind takes over and the moisture decreases on Sunday. The UV index in Tainan City is low, and in other counties and cities is medium to high. The air quality in the north is average, and in other areas it is good.

Affected by the low pressure belt and strong convection, heavy rain fell in Changhua County on the afternoon of the 30th. Fangyuan Township received 130 millimeters of rainfall in one hour and flooded during high sea tides; Yuanlin City issued a level one flood warning, with many roads piling up and Yuanshui turning into a fast-flowing yellow river. Fortunately, there were no casualties.
