受東北季風影響,北台灣多雲並有局部短暫陣雨,今晚至明晨為最低溫時段,新竹以北地區低溫預測16~19度;遠洋三颱(彩雲、諾洛、小熊)預計不會對台灣構成影響,小熊颱風對日本的影響仍有變數,需持續觀察。

東北季風為台灣冬季常見天氣系統,通常帶來北風和較低溫度,尤其影響東北部山區與海岸線。遠洋颱風指生成於遠離台灣海面的熱帶氣旋,其路徑與強度變化需持續監測。
受東北季風影響,迎風面桃園、大台北、宜蘭到花蓮一帶今(6日)雲層較厚,仍有局部短暫陣雨,不過降雨趨緩,今晚明晨(7日)預估是這波東北季風最低溫時間點,民眾要注意保暖;遠洋3颱對台灣不會有影響,小熊颱風是否對日本影響可能還有變數,未來幾天仍需觀察,有旅日計畫民眾要注意颱風資訊。
天氣風險公司資深顧問吳聖宇在臉書表示,今至週四(8日)受東北季風影響,大致維持迎風面雲量較多,偶有局部短暫陣雨,雨勢不大,新竹以南地區為晴到多雲,山區午後仍可能有局部熱對流降雨,但是雨量同樣減小許多。

吳聖宇提醒,週四前都是東北季風比較強的時間點,溫度轉涼最明顯的地方在新竹以北到桃園、大台北、基隆、宜蘭、花蓮北部一帶,夜晚清晨的低溫是需要特別注意的地方,尤其是嘉義以北到宜蘭一帶的郊外空曠地區,預報資料顯示,今晚明晨有機會出現16~19度之間的低溫,應該是這波東北季風溫度相對最低的時候,提醒大家要留意。
遠洋3個颱風因為距離太遠,預估都不會對台灣有影響。彩雲颱風已經在轉向的過程中,明會加速向東北離去並逐漸轉化為溫帶氣旋。跨界而來的諾洛颱風則是偏西走一段距離後也將轉向而去。最新出現的小熊颱風將逐漸增強發展,先往西北一段距離後同樣會拋物線轉向離開。依照目前預報路徑看起來應該也都不會很接近日本,對日本的天氣影響預期有限,不過小熊颱風可能還有變數,未來幾天仍需觀察。

Meteorology expert "Taiwan Typhoon Forum | Weather Emergency" stated that there are still three typhoons coexisting in the northwest Pacific. Typhoon Caiyun is significantly larger in size. It is currently located off the southeastern coast of Japan. The intensity is a moderate typhoon. It will turn to the northeast and accelerate and gradually transform into an extratropical cyclone. The weather in the Shuangbei region has stabilized, with only the northern coast of Keelung and Yilan experiencing brief light rain.

Wu Derong, an adjunct associate professor at the Department of Atmospheric Science of National Central University, pointed out that due to the influence of the northeast monsoon, the rain in northern Taiwan has gradually stopped today and the water vapor has moved southward. From tomorrow to Friday morning, the temperature will be low. The lowest temperature on the plains can drop to 16 degrees, and the temperature difference between day and night is large; the three typhoons (Caiyun, Noro, and Xiaoxiong) have not posed a threat to Taiwan.

China Weather Network reported that due to the continuous rainfall, Hainan will experience widespread rainfall in the next three days (October 6 to 8). The scope of heavy rainfall will gradually expand, and local areas will experience heavy rainstorms or extremely heavy rainstorms. The meteorological department reminds the public to pay attention to travel risks such as slippery roads and reduced visibility, and to plan their itinerary appropriately during the peak return period during the National Day holiday.

The meteorological expert "Taiwan Typhoon Forum - Weather Emergency" released a 48-hour precipitation forecast, pointing out that due to the influence of the northeast monsoon on the 6th, the water vapor will decrease significantly, and the weather in both north and south will gradually stabilize. Only the north coast of Keelung and Yilan will have a chance of short-term light rain, and the rest of the areas will remain sunny.

The Central Meteorological Observatory predicts that there will be heavy to heavy rains in parts of Hainan, Yunnan, Sichuan and other places, rain and snow in northern Xinjiang and western South Xinjiang, and winds of level 5 to 7 in Inner Mongolia and other places. The weather will be fine in most parts of the country.

During the last two days of the National Day holiday, most of the central and eastern regions will have mainly sunny weather, which is conducive to return travel. Affected by the decrease in rainfall, the nighttime radiation temperature dropped significantly, and the minimum temperature continued to bottom out in many places in the south. Guangzhou and other places fell below 20°C for the first time in the second half of this year. Rainfall is still strong in Yunnan, Hainan and other places, with local heavy rains.
