“Nangka is gradually moving away from Hong Kong. However, under its combined effect with the northeast monsoon, local winds are still expected to strengthen further. In particular, the southern part of Hong Kong will experience stronger winds,” the HKO said.

“The Observatory will issue the Gale or Storm Signal No. 8 at or before 6 am,” it added.

The HKO said Tropical Storm Nangka was estimated to be about 450 kilometers south of Hong Kong at 4 am Tuesday and was forecast to intensify gradually and move west or west-northwest at about 22 kilometres per hour in the general direction of the vicinity of Hainan Island.

There will be swells and rough seas and members of the public are advised to stay away from the shoreline and not to engage in water sports, the HKO said.

The Observatory earlier issued the Strong Wind Signal No. 3 on Monday afternoon, adding that this meant that winds with mean speeds of 41 to 62 kilometers per hour were expected.
