HONG KONG – The Hong Kong Observatory said Tuesday that typhoon signal No 1 will remain in force for the rest of the day as two tropical cyclones came within 800 kilometers of the financial hub.

The observatory hoisted the Standby Signal No. 1 at 4:15 am Tuesday morning.

At 1 pm, a tropical depression over the central part of the South China Sea was estimated to be about 760 kilometers south-southwest of Hong Kong, the forecaster said in its latest tropical cyclone warning bulletin.

It was moving slowly towards Hainan Island and has intensified over the past few hours, but was expected to keep a distance of more than 500 kilometers from Hong Kong during the day, the observatory said.
