The hottest July in history has just passed, and high temperature-triggered thunderstorms affected the coast of Guangdong today (2nd). The Observatory issued a special weather warning at about 7:30 tonight, indicating that a thunderstorm belt was crossing Hong Kong from north to south. At 8:30 and 9:30, a strong gust of wind battered Hong Kong, with a wind speed of 80 kilometers per hour, and urged the public to be vigilant and take shelter in a safe place.
During the three-hour period from 7:00pm to 10:00pm, the Observatory recorded a total of 7,000 cloud-to-ground and cloud-to-cloud lightning strikes, and meteorological photography enthusiasts captured the momentary "burst" beauty.

It only eased slightly on Saturday (6th), with occasional showers and a few thunderstorms at first. Next Sunday (7th) there will be sunshine for a short time and a few showers.
The Observatory predicts that an area of low pressure will bring unstable weather to the South China Sea early next week and may develop into a tropical cyclone.
The Observatory is also expected to blow a force of 6 winds offshore on Tuesday and Wednesday (9th and 10th).
According to the Beaufort scale, the average wind speed of Category 6 winds is 41 to 51 kilometers per hour, that is, the wind reaches the level of Typhoon No. 3.

The tropical cyclone is forecast to be closest to Hong Kong in the early hours of next Tuesday
With reference to the forecast of the European Centre for Medium-Range Weather Forecasts (ECMWF), a low pressure area is expected to form in the south of the South China Sea next Monday (8th), and it is expected to move north. And moved to the Leizhou Peninsula area, and then moved to Vietnam.
ECMWF predicts that the central pressure at sea level in this low pressure area is also the lowest at 992 hPa, which is only a tropical storm.
The US Global Forecast System (GFS) predicts that a low pressure area will form in the northwest of the Philippines in the early morning of next Monday, and then rush towards Hong Kong. It will pass about 100 kilometers south of Hong Kong next Tuesday, and then move westward and brush next Wednesday. After the Leizhou Peninsula, it will land in Vietnam next Thursday (11th).
GFS predicts that the low-pressure area will be stronger, and the central pressure at sea level will be as low as 983 hPa, which is a severe tropical storm.
