熱帶性低氣壓TD29預計最快於23日增強為第25號颱風「舒力基」,強度將達中颱等級以上。目前路徑分為北轉或西行侵台兩種可能,若西行則預估下週一外圍環流接近台灣,週二至三影響最劇。氣象專家指出該颱風暴風圈半徑約200公里,屬中等偏小型,未來發展仍具不確定性,需持續觀察預報趨勢。

熱帶性低氣壓TD29位於台灣東南海域,受良好大氣及海洋條件影響,有機會增強為 typhoon 舒力基。其未來路徑受鞍型場影響,可能北轉或維持西行,導致對台灣的影響程度存在顯著不確定性。
熱帶性低氣壓TD29最快今(23日)增強為第25號颱風「舒力基」,未來強度至少會達到中颱等級,目前路徑仍分成提早北轉及維持西行侵台,若持續西行,預估下週一(28日)外圍環流接近,下週二、三影響最劇。
天氣風險公司資深顧問吳聖宇在臉書表示,「舒力基」颱風快今生成,在良好的大氣及海洋條件配合下強度將逐漸增強,接近台灣以東海域的時候強度至少會有中度颱風等級,不過預報資料也顯示這個颱風未來發展的範圍不大,預估的暴風圈半徑大約在200公里左右,屬於中等偏小的類型。

路徑部分,週六(26日)前穩定朝向西北西到西北方向移動,一路往台灣東南方海域靠近。週六颱風來到台灣東南方海域的同時,引導力量會明顯減弱,颱風將陷入鞍型場中,預期週末到下週一(26-28日)這幾天移動速度將顯著放慢。
減慢後發展有兩種可能,一是有機會轉向偏北方向緩慢移動,在台灣以東海域慢慢北上,再逐漸加速往東北方向離去;另有部分預報認為舒力基颱風可能會轉向失敗,也就是陷入鞍型場內減速放慢一段時間後又重新回到西北西路徑繼續往台灣靠近。
下週一隨著舒力基颱風外圍雲系接近,迎風面北部、東北部一帶降雨機會才有機會較為提高,其他地方天氣仍沒有太大變化。如果北轉的位置離台灣較遠,那麼外圍雲系對陸地上的天氣影響就比較有限。
反之,若維持西北西路徑繼續往台灣靠近,下週二、三反而會變成是颱風直接侵襲的天氣型態。因此這個颱風未來的動態變化仍然頗大,未能完全排除侵台的機會,今明兩天的預報趨勢變化還是需要持續觀察留意。

Tropical Depression TD29 is expected to intensify into Typhoon Shuliji today and tomorrow. The current model predictions are divided into two directions: turning north early or continuing westward. If it moves westward and approaches Taiwan, it may have the greatest impact around next Tuesday (29th). Meteorological experts point out that the later development is full of uncertainty.

The Mid-Autumn Festival holiday is approaching. The Meteorological Administration has forecast that the weather will be stable from cloudy to sunny before the weekend, and there is a high chance of enjoying the moon on Mid-Autumn Festival night. Tropical depression TD29 is about 2,000 kilometers away from Taiwan. It is expected to strengthen into a light platform tomorrow and develop into a central Taiwan on Saturday. It may affect the sea surface in eastern Taiwan next Monday and Tuesday, bringing local showers to the north of Taoyuan and Yilan. Pay attention to the accumulation of water during long waves and spring tides.
According to information from the Central Meteorological Observatory, heavy or heavy rains occurred in southern Sichuan, Chongqing and other places yesterday, with local heavy rains. The scope of autumn rain will expand from tomorrow. In the next three days, there will be moderate to heavy rain, local heavy rain or heavy rain in some areas of Shaanxi, Sichuan and other places. We need to be alert to secondary disasters such as landslides and mudslides.
Since September 8, it has continued to rain in many places in West China, with less than one hour of sunshine. It is expected that the rain in West China will intensify and expand to the east from September 23, and the rainfall will continue until the end of September. At the same time, the heat in the south will continue, and the cold air in the north will be weak, and the autumn process will be temporarily stalled across the country.

Tropical depression TD29 is expected to intensify into Typhoon No. 25 "Shuliki" on the morning of the 23rd. It is currently located in the sea near Guam. Meteorological experts pointed out that due to the influence of environmental guidance airflow, it will move towards Taiwan in the future. There is a chance that it will be affected by its peripheral circulation from Tuesday to Wednesday next week.

Taiwan is currently affected by northeasterly winds, with localized short-lived showers in the south and mountainous areas. Tropical Disturbance 91W is expected to develop into Typhoon Shuliki No. 25. The second half of the Mid-Autumn Festival holiday (Saturday to Sunday) may affect the sea surface in the southeast of Taiwan. Clouds will increase in the east and the Hengchun Peninsula, and there is a chance of short-lived showers. People should pay attention to the latest developments and adjust their activity arrangements.
