The Observatory has dropped all typhoon signals at 6:20pm on Wednesday as tropical cyclone Mulan moves further away from Hong Kong.
The forecaster said Mulan will move across the vicinity of Beibu Wan, and will weaken gradually as it enters into the inland areas of Vietnam.
However, it called on members of the public to remain on the alert, as the outer rainbands associated with Mulan will still bring occasional showers and squalls to Hong Kong.
People have also been advised to stay away from the shoreline and not to engage in water sports as there will be swells.
