The Met Office says wave can reach as high as three metres in open waters on the northeast coast of Tobago over the next day and a half.
The Met Office has maintained its rough seas outlook in its latest bulletin.
"Buoy data as well as reports reaching the Trinidad and Tobago Meteorological Service indicate that sea conditions over the last 24 hours continue to be moderate occasionally rough.
In open waters, wave heights are reaching up to 2.5 metres but individual waves particularly along the northeast coast of Tobago are reaching occasionally up to 3.0 metres. In sheltered areas, wave heights are near 1.0 metre and choppy at times.
The winds in the lower levels of the atmosphere remain marginally strong and continue to agitate the surface of the Atlantic Ocean and Caribbean Sea.
Numerical Weather Prediction (NWP) Models indicate that the current strength of the low-level winds will persist over the next 12 to 24 hours, but will strengthen further in 24 to 36 hours and persist into the
As such, sea conditions are expected to continue to be disturbed over the next few days, and become even more agitated in 24 to 36 hours as the low-level winds intensify.
NWP models are maintaining wave heights in open waters, especially north and east coasts, to be 2.5 occasionally 3.0 metres today and to increase to 3.0 to 3.5 metres in the next 24 to 36 hours. Choppy seas will be experienced in sheltered areas particularly around Tobago. Additionally, conditions may be exacerbated during high tide.
SMALL CRAFT OPERATORS, SEA BATHERS AND ALL OTHER MARINE INTERESTS ARE ASKED TO EXERCISE EXTREME CAUTION IN ANY SEA RELATED ACTIVITIES.
The Trinidad and Tobago Meteorological Service is closely monitoring sea conditions and will issue an update at 12:00 p.m. tomorrow Thursday 9th March 2017, or earlier if the situation warrants."
