Establishment of acoustic monitors for dolphin survey between Shek Kwu Chau & Soko Islands
Tuesday, August 27, 2019, Hong Kong

For approximately 29 months, acoustic monitors will be temporarily established on the seabed in the following locations (WGS 84 Datum):
(A) 22 deg. 11.447’N / 113 deg. 59.846’E
(B) 22 deg. 10.399’N / 113 deg. 57.217’E
(C) 22 deg. 09.510’N / 113 deg. 57.151’E
(D) 22 deg. 09.509’N / 113 deg. 56.729’E
(E) 22 deg. 09.773’N / 113 deg. 55.170’E

The acoustic monitor is an instrument for collecting dolphin data. It will be fixed to a cubic precast concrete block of 1.0 metre by 1.0 metre by 1.0 metre on the seabed. The total height of the acoustic monitor and the concrete block above the seabed will be about 2.0 metres.

Laying of the acoustic monitors will be carried out by one derrick barge. One tugboat and one work boat will assist in the works. A working area of approximately 50 metres around the derrick barge will be established. Yellow marker buoys fitted with yellow flashing lights will be laid to mark the positions of the anchors extending from the derrick barge.

Regular diving operations for inspecting and retrieving data from the acoustic monitors will be carried out by a work boat at the above locations from time to time. The hours of operations will be from 0800 to 1800 hours. No operations will be carried out on Sundays.

Vessels engaged in the operations will display signals as prescribed in international and local regulations.

Vessels navigating in the vicinity should proceed with caution and keep clear of the locations at slow speed, bearing in mind there are divers working in the locations.

Tropical Storm Dorian moves into Eastern Caribbean
Tuesday, August 27, 2019, Eastern Caribbean

At 800am AST (1200 UTC), the center of Tropical Storm Dorian was located by surface observations and Martinique radar data near latitude 14.0 North, longitude 61.2 West.

Dorian is moving toward the west-northwest near 13 mph (20 km/h), and this motion is expected to continue through tonight, followed by a turn toward the northwest on Wednesday. On the forecast track, the center of Dorian will move across the eastern and northeastern Caribbean Sea during the next few days, passing near or south of Puerto Rico on Wednesday, move near or over eastern Hispaniola Wednesday night, and move north of Hispaniola on Thursday.

Maximum sustained winds are near 50 mph (85 km/h) with higher gusts. Slow strengthening is forecast during the next 48 hours, and Dorian is forecast to be near hurricane strength when it moves close to Puerto Rico and eastern Hispaniola. Tropical-storm-force winds extend outward up to 45 miles (75 km) from the center…

Dorian is expected to produce the following rain accumulations through Thursday:

Barbados – Additional rainfall up to 1 inch, storm total around 6 inches.
Windward Islands from Martinique to Saint Vincent – 3-6 inches, isolated 10 inches.
Grenadines to Grenada – 1-3 inches.
Leeward Islands from Guadeloupe to Dominica – 1-4 inches.
Puerto Rico and Saint Croix – 2 to 4 inches, isolated 6 inches.
Dominican Republic – 2-4 inches, isolated 6 inches.
This rainfall may cause life-threatening flash floods, especially where totals exceed 4 inches.

Tropical storm conditions are occurring in portions of the tropical storm warning area in the Lesser Antilles and these conditions are expected to continue during the next several hours.
Tropical storm conditions are expected and hurricane conditions are possible in Puerto Rico on Wednesday. Hurricane conditions are possible in the hurricane watch area in the Dominican Republic by late Wednesday and tropical storm conditions are possible in the tropical storm watch area beginning late Wednesday. Tropical storm conditions are possible within the tropical storm watch area in the Lesser Antilles today.

Swells generated by Dorian are affecting portions of the Lesser Antilles and they should continue during the next several hours. Swells are expected to increase along the southern coasts of Puerto Rico and Hispaniola on Wednesday and they could cause life-threatening surf and rip current conditions.
