At 2pm Tuesday the Hazardous Seas Alert – Yellow Level for the northern and eastern coastlines of Trinidad and Tobago is expected to come to an end.
The alert took effect on Friday at 8am.
Trinidad and Tobago Meteorological Service says long period swells are likely to coincide with spring tides as well as a surge of low-level winds.
This can result in choppy sea conditions and battering waves at coastal regions which can be exacerbated during high tides.
Marine interests, mainly nearshore activities including fishing, sea bathing and small craft mooring can be adversely affected.
All marine interests are asked to monitor sea conditions and exercise caution.
