The observatory said the Strong Wind Signal No 3 will remain in force at least until Sunday 10am, but it expects the chance of issuing a higher warning signal to be rather low.

It issued the Strong Wind Signal No 3 at 3.40pm on Saturday, as Super Typhoon Yinxing gradually edges closer to Hong Kong.

"Unless Yinxing adopts a more northerly track closer to the Pearl River Estuary, the chance of issuing higher tropical cyclone warning signals will be rather low," the observatory said.

It said that the Strong Wind Signal No 3 will remain in force at least until Sunday 10am, and depending on the degree of weakening of local winds, the observatory will then consider lowering it to the Standby Signal No 1.

The Education Bureau announced that kindergartens, and schools for children with physical and intellectual disabilities are suspended on Saturday.
