The Hazardous Seas Alert
The Trinidad and Tobago Meteorological Service issued the Hazardous Seas Alert (Yellow Level) on Wednesday at 2:43 PM. The alert goes into effect for Trinidad and Tobago’s northern and eastern coastal areas from 4:00 PM Wednesday, December 20th, 2023, through 8:00 PM Saturday, December 23rd, 2023.
“North-northeasterly long period swells are expected to affect the northern and north-eastern near-shore coastal areas of Trinidad and Tobago. This can result in occasional battering waves in coastal regions, especially during high tides,” according to the Trinidad and Tobago Meteorological Service. This “alert” status considers the possibility of the event occurring. This hazardous sea event is likely.
The alert’s color indicates the event’s severity and probability of the event occurring. Currently, the alert level is Yellow. This means that the hazards are likely, and the severity of impacts is moderate for this particular alert. Large battering waves and a high risk of rip currents are the two main hazards of this swell event.
For a moderate Hazardous Seas Alert, there is the potential for possible injuries, where behavioral changes are required to ensure safety. There may be minor damage to property, with income-earning temporarily disrupted and a couple of communities affected.
The Met Office is advising all marine interests to monitor near-shore sea conditions and exercise caution along affected areas, especially at high tides and continue to monitor updates from official sites.
