HONG KONG – The Hong Kong Observatory said a tropical cyclone in the South China Sea has made landfall in Hainan province and that all tropical cyclone warning signals have been canceled as the tropical depression no longer poses a threat to Hong Kong.

The observatory issued Hong Kong’s first Standby Signal No 1 of this year at around 4 pm Friday 

At 1 pm, the tropical depression was estimated to be about 640 kilometers southwest of Hong Kong, according to the observatory’s latest weather bulletin posted on its website.

It is forecast to move west or west-northwest at about 18 kilometers per hour towards Beibu Wan, the forecasters said.
