This Friday (July 1) marks the 25th anniversary of Hong Kong's return to the motherland. The Observatory is expected to have strong winds and squally showers before and after Friday.
A tropical cyclone may be formed in the South China Sea and will generally move towards the west of Guangdong to Hainan Island later this week. However, there are still variables in its intensity and path. According to the Observatory's analysis, whether the wind will blow in Hong Kong depends on how the high-altitude westerly trough will weaken the high-altitude anticyclone. and the extent to which it retreated eastward.
As the low-pressure system recedes, affected by the active southerly air flow, the weather along the coast of Guangdong is expected to remain unstable next week.

The Observatory said that under the influence of the high-altitude anticyclone, the past few days have been generally sunny in southern China, with mild winds, and the weather has continued to be extremely hot.
However, a broad area of low pressure in the central part of the South China Sea will develop into a tropical cyclone in the next day or two. Later this week, the weather along the south China coast will gradually deteriorate and the wind will strengthen, and squally showers and thunderstorms may occur.

Uncertainty remains if it develops into a tropical cyclone track
If the low-pressure system develops into a tropical cyclone, although there is a greater chance of taking a more westward path, the path remains uncertain.
The latest forecasts from European, British and Japanese models all show that the low pressure system will generally move to the west of Guangdong to Hainan Island after it forms.
However, the US model predicts that the low pressure system will move northwards along the eastern coast of Guangdong.

As for the intensity, the major computer forecasting models have quite different predictions on the intensity of the low-pressure system. The Japanese model predicts that the intensity of the low-pressure system will remain in the form of a monsoon low-pressure, while the American model predicts that it is significantly stronger.

The Observatory has raised the wind forecast by 7.1, and the wind is expected to reach the No. 8 typhoon. The Observatory expects the quasi-tropical cyclone to be predicted to hit Hong Kong with 7.1 squally thunderstorm 7.1?
