The Met Office says that buoy data as well as reports reaching the Trinidad and Tobago Meteorological Service indicate that sea conditions in open waters around Trinidad and Tobago continue to be moderate to rough with wave heights reaching up to 3.5 metres.
It says these above-normal marine conditions are attributed to relatively strong surface winds which are currently agitating the surface of the Atlantic Ocean.
These strong winds are expected to continue for at least the next 2 to 3 days, during which time sea conditions will continue to be disturbed along the exposed coastlines, especially North and East coasts.
The Met Office says that additionally, conditions may be exacerbated during high tide.
It says small craft operators, sea bathers and all other marine interests are advised to exercise extra caution in any sea related activities.
The Met Office says it is closely monitoring weather features that affect sea conditions and an update will be issued at 12:00 p.m. tomorrow, Saturday 30th December 2017, or earlier if the situation warrants.
