The Met Office says northerly swells are forecast to reach coastlines of Trinidad and Tobago in 18 to 24 hours and as a result, sea conditions are expected to gradually deteriorate in 18 to 24 hours.
These swells are forecast to start affecting coastlines from tomorrow afternoon (Thursday 22nd February, 2018).
They are forecast to reach up to 3 metres in open waters and above 1.5 metres in sheltered areas.
Individual wave heights may reach in excess of 3 metres.
The Met Office says that as 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 be exacerbated during high tide.
Fisher folk and citizens, in particular those residing along coastal areas, are being asked to be on the alert for these forecast sea conditions.
The Met Office says all necessary measures must be taken to preserve life and property.
Small craft operators, sea bathers and all other marine interests are being asked to exercise caution in any sea related activities.
