Possibility of tropical cyclone approaching Hong Kong as low pressure area near Guangxi may intensify

1968

10th June 2023 – (Hong Kong) The area of low pressure near Guangxi and the trough of low pressure over the coast of southern China brought showers and thunderstorms to the regions yesterday. Meanwhile, a band of clouds covered the coast of Guangdong. Locally, the weather was mainly cloudy with occasional showers and isolated thunderstorms. Temperatures over many places rose to around 32 degrees. The two low pressure systems will continue to bring showers and thunderstorms to the coastal areas of southern China.

The Hong Kong Observatory has warned that the low pressure area near Guangxi may return and could develop into a tropical cyclone, which may approach Hong Kong in the first to middle of next week. Although there is still some uncertainty regarding the intensity and path of the system, the Observatory has not ruled out the possibility of issuing a tropical cyclone warning signal. The Observatory has urged the public to stay tuned to the latest weather updates.

According to the latest computer models, the low pressure area near Guangxi and the trough of low pressure over the coast of southern China will become more active in the coming days. Some models suggest that the low pressure area may re-enter the Beibu Gulf before moving across the coastal areas of Guangdong from west to east. However, different computer models have different predictions about the location and development of the low pressure area.

Some models predict that the low pressure area will remain closer to the coast, while others predict that it will move to the northern part of the South China Sea. The Observatory is closely monitoring the low pressure area to see whether it will develop into a tropical cyclone. However, it is generally expected that the low pressure area will be quite close to the Pearl River Estuary in the first to middle of next week. If it develops into a tropical cyclone and comes close to Hong Kong, the Observatory may need to issue a tropical cyclone warning signal.

Although there is some uncertainty about whether the low pressure area will develop into a tropical cyclone and its path, computer models generally predict that the two low pressure systems will bring unstable weather to the coastal areas of Guangdong next week. There may be heavy rain and squally thunderstorms midweek. The public is advised to pay attention to the weather conditions and the latest weather updates from the Observatory.
