Tropical Cyclone Warning Bulletin

Here is the latest Tropical Cyclone Warning Bulletin issued by the Hong Kong Observatory.

The Standby Signal, No. 1 is in force.

This means that a tropical cyclone now centred within about 800 kilometres of Hong Kong may affect us.

At 8 a.m., the tropical depression over the central and northern parts of the South China Sea was estimated to be about 610 kilometres southeast of Hong Kong (near 17.8 degrees north 117.5 degrees east) and is forecast to move west or west-northwest at about 12 kilometres per hour, intensifying progressively and edging closer to the western coast of Guangdong.

The circulation of the tropical depression is relatively small. It is expected to maintain a distance of about 500 kilometres or above from Hong Kong during the day today (6 September). The Standby Signal, No. 1 will remain in force for most of the time today.

According to the present forecast, the tropical depression will intensify progressively and edge closer to the western coast of Guangdong. Depending on the intensity of the tropical cyclone, the distance of its strong winds from Hong Kong and the change in local wind conditions, the Observatory will assess the need for issuing the Strong Wind Signal, No. 3 at first tomorrow (7 September).

The weather is expected to be mainly fine in Hong Kong today. It will be extremely hot during the day with temperatures of around 35 degrees in the urban areas, and temperatures could reach 38 or 39 degrees over the northern part of the New Territories. With the tropical cyclone edging closer, local winds will strengthen gradually and the weather will become unsettled tomorrow. It will be windy with heavy squally showers and thunderstorms on Monday (8 September). Seas will be rough with swells. Members of the public are advised to stay away from the shoreline and not to engage in water sports. Due to storm surge, there may be flooding in low-lying coastal areas on Monday morning.

1. Precautions should be taken. Drains should be cleared of obstructions, and windows and doors should be checked.

2. People in areas of exposed to high winds or in low-lying areas should take precautions against strong winds and flooding.
