The city is bracing for unstable weather this week, with a potential typhoon expected to approach shortly after Wednesday (Sep 17), according to the Observatory.
The Observatory raised its wind forecast, indicating that strong winds and heavy rain could occur later this week.
The weather forecaster previously mentioned that three low-pressure systems are developing in the South China Sea, with at least two likely to affect the Guangdong coast.
It is anticipated that one of the low-pressure troughs will move in the general direction of the vicinity of Hainan Island, but its strength and path remain uncertain.
Under its influence, windy weather with more showers is expected in the middle and later parts of this week.
Another area of low pressure may develop over the western North Pacific to the east of the Philippines later this week, possibly drawing closer to the city on Thursday (Sep 18) to Friday (Sep 19) and intensifying gradually.
According to the nine-day weather forecast, the winds on Thursday (Sep 18) may reach levels of Force 4 to 5, with some high ground areas potentially experiencing Force 6—classified as "strong winds" on the Beaufort scale.
Notably, sunny intervals with isolated thunderstorms are expected from Monday (Sep 15) to Wednesday (Sep 17), followed by unsettled weather with increased showers later in the week.
The last low-pressure system is projected to have the highest intensity and is expected to approach the vicinity of Luzon early next week.
However, its route remains uncertain and the Observatory advised the public to stay tuned for updates.
