A suspected case of disappearing into the sea occurred in Saigon.
At about 2 am today (19th), when the police patrolled the waters of Huang Yizhou near Kau Xizhou, it was reported that a yacht was empty, but a key was inserted in the keyhole. After investigation, it was suspected that a foreign man fell into the sea and disappeared.
The police once asked the Government Flying Service to send a helicopter to assist, but the helicopter was eventually unable to be dispatched due to poor visibility at the scene; the fire and marine police are currently searching the scene.
According to the Observatory, the visibility in Hong Kong has dropped to below 500 meters due to heavy fog; the visibility of Waglan Island has dropped to below 100 meters.
The Observatory reminded that the visibility of the sea surface is very low, and motorists should navigate carefully.
The Marine Department reminded captains, local captains and ship leaders yesterday (18th) that since the visibility in some waters of Hong Kong is less than 2 nautical miles, it is necessary to sail at a safe speed and drive with extreme caution in Hong Kong waters.
Vessels must make appropriate sound signals in accordance with the International Regulations for Preventing Collisions at Sea when they are sailing or at anchor.
In addition, when radar is used without the aid of sufficient plotting equipment, the information obtained is quite insufficient, so this must be taken into account in the interpretation.
The Vessel Traffic Surveillance Centre will broadcast visibility reports on VHF radio channels 02, 12, 14, 63 and 67.
In the event of an accident, immediately report to the Vessel Navigation Monitoring Centre at 2233 7801.
The Observatory reminded that the visibility of the sea surface is very low, and motorists should navigate carefully.
