Severe tropical storm "Siamba" was gradually approaching on July 1, the return day. As of 12:00 noon today (1st), the No. 3 strong wind signal was in force.
The Observatory predicts that Siamba will generally move towards the western coast of Guangdong on today and tomorrow (2nd), and gradually intensify, and its associated outer rainbands will also bring squally showers and thunderstorms.
The Observatory expects that winds of magnitude 8 will be reached between the offshore and highland areas of Hong Kong, that is, the winds of Typhoon No. 8 have been reached.
In addition, another tropical cyclone is also formed in the northwestern Pacific Ocean. The Observatory expects Tropical Storm Airy to move northerly in the next one or two days, but it is forecast to move away from Hong Kong and generally move towards the Ryukyu Islands.
Affected by the active southerly airstream, the coastal weather in Hong Kong is expected to remain unstable next week, with cloudy and rainy weather continuing until next Saturday (9th).

The Observatory said that at 12 noon, Severe Tropical Storm Siamba gathered about 410 kilometers south of Hong Kong and was expected to move northwestward at a speed of about 18 kilometers per hour, generally moving towards the western coast of Guangdong.
In the past few hours, Siamba continued to move northwestward, and its associated rainbands occasionally brought heavy showers and violent gusts to the coast of Guangdong. Strong winds were generally blowing in Hong Kong, with stronger winds in the south.
The Observatory also expects that according to the current forecast path, Siamba will maintain a distance of more than 300 kilometers from Hong Kong most of the time today, and the No. 3 strong wind signal is expected to be maintained before 5 pm.
Whether the No. 8 Gale or Storm Signal will be issued later will depend on the development of Siamba and changes in local winds.
In 2001 and 2013, July 1st typhoon signal No. 3 was hoisted
According to the tropical cyclone track information from the Observatory, it is expected that Siamba will soon enter the range of 400 kilometers in Hong Kong, and has maintained a distance of nearly 400 kilometers since then.
The Observatory also predicts that Siamba will intensify into a typhoon at 8:00 a.m. tomorrow and make landfall in the area of Zhanjiang City. It will weaken into a severe tropical storm on Sunday (3rd).
As for Avery, it is expected to intensify into a severe tropical storm on Sunday and move towards the Okinawa area.
It is worth mentioning that Siam Ba is the third tropical cyclone since the 25th anniversary of the return of the motherland to the Hong Kong Observatory to issue a tropical cyclone warning on July 1.
For the last two tropical cyclones, Typhoon "Durian" in 2001 and Severe Tropical Storm "Umbia" in 2013, the two highest tropical cyclone warnings were both typhoon No. 3.
