From the Hong Kong observatory site:
The No. 8 Northeast Gale or Storm Signal is in force.
This means that winds with mean speeds of 63 kilometres per hour or more are expected from the northeast quarter.
At 11 p.m., Tropical Storm Doksuri was centred about 100 kilometres south-southeast of Hong Kong Observatory (near 21.4 degrees north 114.4 degrees east) and is forecast to move west-northwest at about 30 kilometres per hour moving closer to the Pearl River Estuary.
Under the influence of Doksuri, local winds continued to strengthen, reaching gale force in Hong Kong. On the present forecast track, Dorksuri will be closest to Hong Kong in the next few hours, passing within 100 km to the south-southwest.
Since there are rough seas, you are advised to stay away from the shoreline and not engage in water sports.
In the past hour, the maximum sustained winds recorded at Tate's Cairn and Waglan Island were 90 and 89 kilometres per hour respectively.
