10th June 2025 – (Hong Kong) The Hong Kong Observatory issued a special weather advisory this morning, indicating that the expansive low-pressure area in the central South China Sea is expected to gradually intensify into a tropical depression from this afternoon to tomorrow morning (11th June). It is anticipated that this system will be named “Wutip,” with the Observatory likely to issue the Standby Signal, No. 1 earliest tomorrow morning.
The tropical cyclone is projected to move towards Hainan Island and the western Guangdong coast in the coming days. Depending on its proximity to Hong Kong and its development rate, the Observatory will assess the necessity of issuing a higher tropical cyclone warning signal on Thursday (12th June). As the cyclone approaches, the weather is expected to be windy with occasional squally showers towards the end of the week, accompanied by rough seas. The public is advised to stay updated with the latest weather forecasts.
Under the influence of an anticyclone aloft, conditions remain fine and extremely hot over the Guangdong coast. Concurrently, the low-pressure system in the South China Sea is gradually intensifying, hinting at the formation of a tropical cyclone. Additionally, a band of thundery showers associated with this system is affecting the northern regions of the South China Sea.
Weather predictions for this afternoon and tonight in Hong Kong indicate mainly fine conditions with extreme heat and a possibility of isolated showers, with temperatures reaching around 35 degrees. Expect light to moderate east to northeasterly winds.
The outlook for Hong Kong suggests continued hot weather with a few showers tomorrow, followed by windy conditions and rough seas in the upcoming days. Heavy squally showers are expected on Friday and Saturday.
The broad low-pressure system currently positioned over the central South China Sea is anticipated to gradually transform into a tropical cyclone today and tomorrow morning. It is expected to move towards Hainan Island and the western Guangdong coast in the following days, bringing squally showers and thunderstorms to the northern regions of the South China Sea later this week. Windy conditions with rough seas are expected. The tropical cyclone will then move inland. Due to an active southerly airstream, a few showers are predicted over Guangdong early next week.
The Hong Kong Observatory’s early morning satellite imagery on June 10th displayed the expansive low-pressure system consolidating in the central South China Sea, situated approximately 800 kilometres from Hong Kong. As per the latest updates, this system is progressing towards tropical depression status, with the Observatory set to issue the Standby Signal, No. 1 earliest tomorrow morning.
Forecasts from various official meteorological agencies in mainland China, Taiwan, Japan, and South Korea have upgraded this system to a tropical depression, predicting its movement towards Hainan Island over the next two days. The consensus points to a west-northwest track, with a potential landfall on Hainan Island before transitioning towards a second landfall near Zhanjiang to Maoming in western Guangdong on Saturday (14th June), approximately 400 kilometres away from Hong Kong. The Central Meteorological Observatory of mainland China foresees an upgrade to typhoon status before the cyclone lands on Hainan Island.
The Hong Kong Observatory’s latest satellite images on 10th June reveal the consolidation of the broad low-pressure area in the central South China Sea, positioned approximately 800 kilometres from Hong Kong. This system, located directly south of Hong Kong, is expected to intensify into a tropical depression from this afternoon to tomorrow morning.
The Observatory anticipates the tropical cyclone to move towards the Hainan Island and western Guangdong coast regions in the latter part of this week. Depending on its proximity to Hong Kong and its development rate, a reassessment for the issuance of higher tropical cyclone warning signals is planned for Thursday (12th June). As the cyclone approaches, strong winds and occasional squally showers are expected towards the end of the week, with heightened sea swells.
The China Meteorological Administration has reported the formation of a tropical depression in the central South China Sea this morning. Located around 285 kilometres east-southeast of Sansha City (Yongxing Island) in Hainan, the system exhibits maximum winds near the center reaching force 7 (15 meters per second) and a minimum central pressure of 1,000 hPa.
The Observatory forecasts this low-pressure system to move westward at a speed of 10 kilometres per hour, gradually strengthening. It is predicted to intensify into the first typhoon of the year within 24 hours, gradually approaching the southern part of Hainan Island to the western coast of Guangdong in the next few days. Landfall in the aforementioned coastal regions is expected around Friday (13th June), and the intensity will gradually diminish afterwards. The Observatory predicts strong winds of force 6 to 7 over most of the South China Sea, Guangdong coast, and the eastern coast of Hainan Island in the next two days.
Anticipated developments suggest the tropical cyclone will upgrade to a tropical storm tonight (10th June) and intensify into a severe tropical storm by tomorrow night (12th June). By Thursday night (12th June), it is expected to strengthen into a typhoon and is forecasted to make landfall in the southern part of Hainan Island on Friday morning (approximately 580 kilometres southwest of Hong Kong). Subsequently, the system will weaken into a severe tropical storm and veer northeastward, landing again in the Zhanjiang area (approximately 400 kilometres southwest of Hong Kong) on Saturday morning. Following this, it will move towards the northern part of Guangzhou and weaken into a tropical depression over inland areas.
Forecasts from the Taiwan Central Weather Administration predict the tropical cyclone to make landfall in the southern part of Hainan Island on Friday morning, passing through the western part of the island before landing again in the southwest region of Leizhou Peninsula on Saturday morning, subsequently moving northeast and weakening. The intensity is forecasted to reach up to tropical storm levels (maximum wind speed near the centre of 23 meters per second).
The Japan Meteorological Agency forecasts the tropical depression over the central South China Sea to move northwestwards towards Hainan Island, making landfall in the eastern part of the island on the 13th, then shifting northeastwards towards Zhanjiang and Maoming on the 14th. Forecasts from the Japan Meteorological Agency and the South Korean Meteorological Agency align, predicting a landfall in the southern part of Hainan Island, slightly to the east, with a subsequent landfall near Zhanjiang. The expected intensity ranges from tropical storm to severe tropical storm levels.
