今晚(1日)東北季風報到,入夜後迎風面北海岸、東北角、宜蘭一帶將開始降雨,明後天(2~3日)桃園、大台北、基隆北海岸、宜蘭、花蓮北部一帶降雨增多。對此,台灣整合防災工程技術顧問公司總監賈新興表示,明天起將迎來「兩段式降溫」,尤其第2波,北部空曠地區低溫將下探18度!
賈新興在臉書PO文表示,換季薄外套真的要拿出來了!今天全台依然炎熱,但明天起將迎來「兩段式降溫」,尤其第2波,北部空曠地區低溫將下探18度!另外,「彩雲颱風」已在今天凌晨2點生成,中太平洋也將有「跨界颶風NOLO」移入;今天更特別為大家整理了「日本與韓國的最新賞楓情報」!

賈新興指出,兩階段降溫時程(第2波非常有感),第1波(10月2日明天起):微弱東北風南下,桃園以北及宜蘭稍有轉涼感受;第2波(10月5日起):偏強東北季風影響!這波降溫顯著有感,台北高溫將從原本的33°C一路下滑至25~27°C,夜間清晨低溫約 20°C,北部較空曠地區甚至有機會下探至18°C左右!早出晚歸或騎車請務必準備好防風薄外套,迎風面降雨:受東北季風影響,桃園以北、基隆北海岸及宜蘭降雨機率高且水氣偏多(特別是宜蘭需留意局部較大雨勢),出門務必攜帶雨具。
賈新興續指,熱帶系統最新動向(彩雲颱風生成✕NOLO跨界移入),彩雲颱風已於今日(10/1)凌晨2點正式生成!目前環境導引偏弱,先向西移動,隨後受高壓導引北轉朝「日本東南方外海」前進。對台灣無直接影響,但10月5日至7日前往日本旅遊的朋友請注意外圍環流。
賈新興分析,依美國國家颶風中心預測,中太平洋的「NOLO」預計於10月4日前後跨越180度經線,移入西北太平洋成為跨界颱風,海外旅遊必看(日本、韓國 楓紅預報),日本:北海道大雪山、層雲峽一帶高山已進入變色期;本州山區預計10月中旬陸續染紅;東京、大阪、京都等平地預計落在11月中旬至11月下旬;韓國:北部雪嶽山、五台山預計在10月上旬率先轉紅;全羅道內藏山、智異山及南部濟州島漢拏山則落在10月底至11月上旬迎來全盛期。
賈新興提醒,生活保健與安全叮嚀,初秋溫差拉大,請留意呼吸道保養與皮膚保濕,東北季風影響期間台灣海峽風浪增強、沿海有長浪,海邊活動或出海作業請特別注意安全!

During the National Day holiday, most areas across the country have good weather conditions and are suitable for travel. It will be mainly sunny to cloudy in the north, and there will be precipitation in North and Northeast China; it will rain first and then become clear in the south, and the rain will be stronger in the southwest. The meteorological department reminded that urban traffic pressure in Guangdong, Zhejiang, Jiangsu, Sichuan, Hunan and other places will be severe. There will be heavy to heavy rains in Fujian, Hunan, Chongqing, Guizhou and other places, and some highways will be slippery and prone to water accumulation. The two waves of cold air relay influence, the coolness in the north becomes more intense, and the heat in the south subsides. In the second half of the Yangtze River, the temperature drops to about 15℃ in the morning and evening.

Wu Derong, an adjunct associate professor at the Department of Atmospheric Science at Central University, pointed out that it will turn to rain in the northern and eastern half of the country from tomorrow to next Sunday, and it will become cooler and the temperature will drop significantly in northern Taiwan next Monday and Tuesday; Light Typhoon Colorful Cloud No. 26 formed over the sea northeast of Guam early this morning and is expected to develop into a large typhoon and head toward the sea southeast of Japan and will not invade Taiwan.

Typhoon No. 26 "Caiyun" was generated on the 1st. It is expected to develop into a strong and wide-circulation system. However, it will not directly affect Taiwan as it moves northward. Instead, it will indirectly promote the northeast monsoon that will last for a long time near Taiwan next week. The northern and eastern half will be significantly cooler. Rainfall will be concentrated on the north coast, the northeastern corner, Yilan and other places. The daytime high temperature in Taipei after next Monday is expected to remain at 25-30 degrees, and the nighttime low temperature will be 20-25 degrees.

On the first day of the National Day holiday, the cold air continues to move eastward and southward, and many places in the south will join the cooling process. From October 3rd to 4th, a new wave of cold air will move southward, and temperatures in many places in the north and south will hit record lows in the second half of this year. The rainfall in the south is relatively large, and some areas in the southwest need to be prepared for secondary disasters.

The Central Meteorological Administration predicts that the arrival of the northeast monsoon originally scheduled for October 1 will be postponed by one day, and rain will turn to the north and northeast from Friday. Wang Pinxiang, a forecaster from the Meteorological Administration, said that during the northeast monsoon, the temperature will drop below 30 degrees, about 27 to 28 degrees during the day, and about 24 degrees at night. He also predicted that there will still be some short-lived showers on the north coast of Keelung, the eastern half and the Hengchun Peninsula on Saturday and Sunday.

Tropical depression TD30 is located in the northeast and east of Guam. It is expected to intensify into Typhoon "Caiyun", the No. 27 internationally numbered typhoon, which can reach the intensity of a severe typhoon and move northward. However, it is not expected to directly affect Taiwan, and the probability of affecting the Japanese mainland is not high. Whether the external circulation will affect Kantō and Tohoku of Japan still needs to be observed in the later path.
