Strong Wind Signal, No. 3 to remain in force before 2am tomorrow


9th August 2022 – (Hong Kong) The broad outer rainbands associated with Mulan are affecting the northern part of the South China Sea and the coast of Guangdong, bringing heavy showers, violent gusts and thunderstorms to the territory. According to the present forecast track, Mulan will edge closer to the coast of Guangdong tonight and tomorrow morning. However, since the region of gale force winds near the centre of Mulan is relatively small, unless Mulan intensifies significantly or local winds show a clear sign of strengthening, the Strong Wind Signal, No. 3 will remain in force before 2am tomorrow. The Observatory will closely monitor the development and movement of Mulan to assess the need for issuing higher signals.

Locally, winds are generally strong. However, under the influence of showers, there will be violent gusts with occasional gale force winds over the offshore waters and on high ground. Besides, as the astronomical high tide will occur tomorrow, storm surge induced by Mulan may lead to flooding in low-lying areas tomorrow morning. Members of the public should be on the alert, and take precautions against high winds and flooding as early as possible.

In the past hour, the maximum sustained winds recorded at Tap Mun, Cheung Chau and Tai Mei Tuk were 83, 69 and 66 kilometres per hour with maximum gusts 98, 77 and 85 kilometres per hour respectively.

Tropical Cyclone Mulan will move towards the vicinity of western Guangdong and Hainan Island, and intensify gradually today and tomorrow. Under the influence of its outer rainbands, it will be windy with heavy squally showers and thunderstorms over the northern part of the South China Sea and the coast of Guangdong in the next couple of days. Seas will be very rough with swells. A broad trough of low pressure will continue to bring showers to the northern part of the South China Sea in the latter part of this week. With the anticyclone aloft strengthening slightly, the weather will improve over southeastern China early next week.
