The Hong Kong Observatory issued a No. 9 Tropical Cyclone Warning Signal at 8am on Sunday as super typhoon Mangkhut is in Hong Kong.
At 8am, Mangkhut was centred about 220 kilometers south-southeast of Hong Kong (near 20.6 degrees north 115.2 degrees east) and is forecast to move west-northwest at about 30 kilometers per hour towards the coast of western Guangdong.
However, the typhoon has weakened slightly into a severe typhoon.
Mangkhut continues to move steadily towards the coast of western Guangdong, edging further closer to Hong Kong with a high threat.
According to the present forecast track, Mangkhut will be closest to the Pearl River Delta around noontime today, skirting about 100 kilometres to the south of Hong Kong. Local winds will continue to strengthen. The Observatory will consider the need for issuing the Hurricane Signal, No. 10, depending on the local wind changes.
Although Mangkhut has weakened slightly, its circulation is extensive and winds remain fierce. Mangkhut’s intense rainbands are affecting Hong Kong, bringing frequent squalls and heavy rain. Sea will be high with swells. As winds change from northeasterly to southeasterly, areas which were previously sheltered may become exposed. Members of the public should stay on high alert, and note the impacts of changes in wind direction.
Under the influence of storm surge, a high water level of about 3.5 meters or more above chart datum is expected at the Victoria Harbour between 2pm and 4pm today; and a high water level of about 4.0 meters or more above chart datum is expected at Tai O between 3pm and 6pm today. The high water level may cause severe flooding in low-lying areas.
In the past hour, the maximum sustained winds recorded at Tate’s Cairn, Waglan Island and Cheung Chau were 114, 94 and 63 kilometers per hour with maximum gusts 149, 113 and 98 kilometers per hour respectively.
The Observatory said people should stay away from the shoreline, and not to engage in water sports.
The Observatory issued a typhoon signal No. 1 at 10:20pm on Friday, a signal No. 3 at 4:20pm on Saturday and a signal No. 8 at 1:10am on Sunday.
