The Met Office says northerly swells are expected to continue for 24 hours and are expected to peak today.
The Met Office is continuing its Rough Seas bulletin in this regard.
The following is the latest bulletin issued by the Met Office.
"Northerly swells have been affecting coastlines of Trinidad and Tobago over the last 24 hours and this swell event is expected to peak today, Friday, 23rd February, 2018.
The swells are forecast to continue affecting coastlines over the next 24 hours.
These northerly swells are forecast to reach 3.0m in open waters and above 1.5m in sheltered areas.
Individual wave heights, however, may reach in excess of 3.0m at times.
As these northerly swells approach shallow waters, the wave heights can increase sharply and as a result, may lead to battering waves especially along the coastlines.
Conditions will worsen during high tide especially along sheltered areas and northern coastlines.
Fisherfolk and citizens, in particular those residing along coastal areas, are asked to be on the alert for these forecast sea conditions.
All necessary measures must be taken to preserve life and property.
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, Saturday 24 th February 2018, or earlier if the situation warrants."
