The Hong Kong Observatory and the Macao Meteorological and Geophysical Bureau will issue T1 today.
The Hong Kong Observatory and the Macao Meteorological and Geophysical Bureau will issue tropical cyclone signal No.1 (T1) today, 22 September 2025, as Super Typhoon Ragasa moves closer to the region.
According to current forecasts, Ragasa is expected to gradually approach the coast of Guangdong on Tuesday, 23 September. Weather conditions in both Hong Kong and Macao will begin to deteriorate rapidly, with the winds significantly strengthening.
On Wednesday, 24 September, gale to storm-force winds are expected to prevail, and winds may reach hurricane force offshore and on high ground. Heavy squally showers and thunderstorms will affect both cities, and seas will become very rough with large swells. The sea level over coastal areas by then may be similar to that of Typhoon Hato in 2017 and Mangkhut in 2018.
In view of the possible serious threats that Ragasa may pose, Hong Kong's Chief Secretary for Administration Chan Kwok-ki chaired a meeting of the steering committee on handling extreme weather on 21 September to co-ordinate the preparatory work of relevant departments. Hong Kong's Education Bureau will also announce today (22 September) the arrangements for school attendance on Tuesday, 23 September.
Meanwhile, Hong Kong's Labour Department reminded employers to make prior work arrangements for employees in times of and after tropical cyclones, rainstorms, and extreme conditions as early as possible, including arrangements on reporting for duty, release from work, resumption of work, and remote work (if applicable).
In drawing up and implementing the arrangements, employers should give prime consideration to employees' safety and the feasibility of employees travelling to and from their workplaces, etc. Employers should also give consideration as much as possible to the different situations and actual difficulties faced by individual employees, and adopt a sympathetic and flexible approach.
Both the Hong Kong Observatory and the Macao Meteorological and Geophysical Bureau are calling on the public to pay close attention to the latest weather information, take early precautions against wind damage and flooding, and prepare essential emergency supplies.
