Mere hours after the last Hazardous Seas Alert was discontinued by the Trinidad and Tobago Meteorological Service (TTMS), which was in effect for the previous 13 days, the country has been placed under another, more severe Hazardous Seas Alert.
Long-period swells originating from the far North Atlantic Ocean have travelled thousands of kilometres to produce large, breaking waves along Atlantic- and northern-facing coastlines across the Lesser Antilles.
Since December 9, these waves generally have peaked around 3 metres (10 feet), but from Friday afternoon, waves along T&T’s northern coasts are forecast to reach as high as 3.5 metres (11.5 feet).
Coastal communities along Trinidad and Tobago’s northern and northeastern coastlines have been placed under the Met Office’s first-ever Orange-Level Hazardous Seas Alert from 2 pm Friday, December 23, 2022, through noon Wednesday, December 28, 2022.
Through Monday, December 26, 2022, spring tides are also ongoing. Spring tides are higher-than-usual high tides and lower-than-usual low tides due to the new and full moons that occur monthly.
According to the TTMS, T&T should also expect choppy conditions along northern-facing coastlines in the Gulf of Paria, with large waves and hazardous conditions amplified during high tides.
The Met Office says effects from these swells are forecast to begin initially along the northern coasts of Tobago and then Trinidad within a couple of hours after.
For an Orange-Level Hazardous Seas Alert, severe impacts are likely. There is the potential for a loss of a single life or serious injuries; physical defences are needed, major losses are possible in confined areas, income earning is impossible for several days, and several communities are affected where external help is needed for recovery.
Impacts include dangerous conditions for swimming and small craft operations, very high surf, dangerous rip currents, moderate to significant beach erosion, and coastal flooding in low-lying areas.
The TTMS advises sea bathers, fishermen, small craft operators, and other coastal interests to secure lives, livelihoods, and coastal property, exercise extreme caution along the coast, prepare for dangerous breaking waves and currents, follow the instructions of lifeguards and monitor official news sources.
