Status of Tropical Cyclone Warning Signal

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 noon, the tropical depression over the northeastern part of the South China Sea was estimated to be about 500 kilometres east-southeast of Hong Kong (near 20.0 degrees north 118.3 degrees east) and is forecast to move northwest at about 18 kilometres per hour in the general direction of the coast of eastern Guangdong.

In the past few hours, the tropical cyclone continued to move across the northeastern part of the South China Sea. The circulation of the tropical cyclone is relatively small and it will maintain a distance of about 300 kilometres or more from Hong Kong for most of the time today. The Standby Signal, No. 1 will remain in force today.

According to the present forecast, the tropical cyclone will intensify gradually while edging closer to the coast of eastern Guangdong today and tomorrow. Under the influence of the northeast monsoon, it will then turn westwards, moving closer to the vicinity of the Pearl River Estuary. However, there are uncertainties in its landfall position and intensity. 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 of issuing higher tropical cyclone warning signals tomorrow.

Locally, the weather is expected to remain very hot this afternoon. Winds will strengthen with more showers gradually tomorrow. There will be occasional squally showers and thunderstorms on Saturday. Showers will be heavy at times. There will be swells. Members of the public are advised to stay away from the shoreline and not to engage in water sports.
