"Ragasa has an extensive circulation with fierce winds, posing a severe threat to the coast of Guangdong," it said. Ragasa is expected to make landfall in Guangdong on Wednesday.
As of 13:00 local time (06:00 GMT) on Tuesday, Ragasa was estimated to be about 390km southeast of Hong Kong, authorities said. They added that they planned to raise the storm alert to category 8 at 14:20 local time (07:20 GMT).
"The Government advises members of the public with long or difficult home journeys or having to return to outlying islands to begin their journeys now," the authority wrote in a Facebook post. "The Government is now making arrangements to release its employees accordingly."
Ragasa is expected to brush past Hong Kong and make landfall in China on Wednesday.
