The Hong Kong Observatory hoisted the level three tropical cyclone warning at 4:10 pm on Monday, with Tropical Storm Cempaka around 180 kilometres southwest of the city.
The weather warning means people should brace for winds of speeds between 41 to 62 kilometres per hour, with heavy showers and squalls expected until Tuesday.
The observatory urged people to secure objects that could be blown away and ensure all windows and doors are securely closed. People who live in low-lying areas should take precautions against flooding.
The Labour Department called on bosses to make arrangements to ensure the safety of their workforce. “Employers should give prime consideration to employees’ safety and the feasibility for employees to travel to and from their workplaces,” a spokesperson said.
“If employees are required to work in times of typhoons and rainstorms, employers should ensure that the risks at work are reduced as far as reasonably practicable,” he said.
