The Hong Kong Observatory is closely monitoring the development of Severe Typhoon Gaemi in the western Pacific. The National Meteorological Centre of the China Meteorological Administration (CMA) has indicated that Gaemi could intensify into the first super typhoon of the year within the next 24 hours.
Gaemi is currently demonstrating symmetrical development, supported by the southwest monsoon and an influx of moisture and heat from tropical waters. As of Tuesday afternoon, the typhoon has already reached severe status with winds of 45-50 meters per second (approximately 160-180 km/h).
Forecasts predict that Gaemi will make initial landfall along the coast of northern and central Taiwan on Wednesday evening, maintaining severe typhoon strength. The system is then expected to cross Taiwan and make a second landfall in the Fujian region of China by Thursday night, with wind speeds ranging from 33-42 meters per second (approximately 120-150 km/h).
After its second landfall, Gaemi is projected to move inland, affecting the Jiangnan region and potentially extending its impact further. The exact path and intensity of the typhoon as it moves inland remain uncertain, particularly regarding its interaction with cold air from the westerlies, which could lead to extreme rainfall events.
While the outer bands of Typhoon Gaemi are bringing fine weather to southeastern China, including Hong Kong, the weather in the coming days is forecast to see increasing winds, isolated showers, and thunderstorms. Over the weekend, the influence of Gaemi is likely to result in more frequent showers in Hong Kong.
Given these conditions, the Hong Kong Observatory is closely monitoring Gaemi's trajectory and local wind conditions. Depending on the factors, there is a possibility that a Standby Signal No. 1 or a Strong Monsoon Signal will be issued, indicating that residents should prepare for potential weather disturbances.
香港天文台密切監察強烈颱風嘉美,可能發出一號戒備信號
2024年7月23日 - 香港天文台正密切監察西太平洋的強烈颱風嘉美的發展。中國氣象局國家氣象中心表示,嘉美可能在未來24小時內升級為今年首個超級颱風。
嘉美目前正呈現對稱性發展,得到西南季風以及熱帶水域的水汽和熱量支持。截至星期二下午,颱風已達到強烈級別,風速介乎每秒45-50米(約160-180公里/小時)。
預報顯示,嘉美將於星期三晚上在台灣北部及中部沿海登陸,維持強烈颱風強度。該系統預計會橫越台灣,並於星期四晚間在福建沿海地區再次登陸,風速介乎每秒33-42米(約120-150公里/小時)。
在第二次登陸後,嘉美預計將向內陸移動,影響江南地區,並可能延伸到更廣泛地區。颱風在內陸移動時的路徑和強度尚存在不確定性,特別是它與西風帶帶來的冷空氣的相互作用,可能導致極端降雨事件。
雖然嘉美的外圍雲帶為華南地區(包括香港)帶來晴朗天氣,但未來幾天預計會出現增強的風勢、局部驟雨和雷暴。在周末,颱風嘉美的影響可能導致香港出現更頻繁的驟雨。
鑒於這些情況,香港天文台正密切監察嘉美的軌跡和本地風況。根據情況的發展,可能會發出一號戒備信號或強烈季候風信號,提示居民做好應對天氣干擾的準備。
