Hazardous Seas Alert Continues For T&T

The Hazardous Seas Alert

As anticipated, strong low-level winds are ongoing across the Southern Windwards, including Trinidad and Tobago. These winds have agitated seas mainly in our eastern and northern coastal waters.

The Trinidad and Tobago Meteorological Service maintained the Hazardous Seas Alert (Yellow Level) for our coastal waters, which began at 8:00 PM Sunday 14th February 2021 through 2:00 PM Thursday 18th February 2021.

Trinidad and Tobago is NOT under any tropical storm threat, watch or warning.

Information from the Trinidad and Tobago Meteorological Service concerning the Hazardous Seas Alert in effect from 8:00 PM Sunday through 2:00 PM Thursday.

“Strong low-level winds have agitated sea conditions, mainly around North and East Trinidad and Tobago. Waves are reaching heights between 2.5 m and 3.0 m in open waters. Sea conditions in sheltered areas will continue to be choppy at times.” according to the Trinidad and Tobago Meteorological Service. This “alert” status takes into account the possibility of the event occurring. This event has been observed.

The color of the alert indicates the severity of the event and the probability of the event occurring. Currently, the alert level is at Yellow. This means that the hazard has been observed, and you need to be aware of the impacts of hazardous seas in your area. Moderate impacts are expected, so there is the chance of possible injuries, and persons would need to take action to ensure safety. There may be minor property damage.

Impacts on T&T’s Shorelines

Impacts possible from rough seas include the following:

  • Loss of life;
  • Injuries;
  • Sea search and rescue disruptions;
  • Disruptions to sea transportation;
  • Scarcity of seafood;
  • Damage or loss of boats and fishing equipment;
  • Disruptions to marine recreation and businesses
  • Economic losses.

Other impacts from the high winds, apart from hazardous seas, include:

  • Injuries;
  • Coastal erosion;
  • Localized disruptions of businesses;
  • Disruption to outdoor and sporting activities;
  • Disruption of transportation (air and especially sea) and

Winds could make some outdoor activities uncomfortable, if not outright dangerous. High winds can create dangerous fallen or blowing objects.

The strongest winds and the highest and most dangerous seas are forecast to begin next week. The highest seas will take place in the Atlantic waters of the islands.

There is also the potential for loss of life. There is a high risk of rip currents, strong currents that can carry even the strongest swimmers out to sea.

Rip currents are powerful channels of water flowing quickly away from the shore, which occur most often at low spots or breaks in the sandbar and near structures such as groins, jetties, and piers. If caught in a rip current, relax and float. Don’t swim against the current. If able, swim in a direction following the shoreline. If unable to escape, face the shore and call or wave for help.

There is also the potential for injuries to beachgoers; beach closures; localized disruptions to marine recreation and businesses and financial losses.

High tides combined with onshore wind and swell actions could result in localized coastal flooding and beach erosion.

High surfs can knock spectators off exposed rocks and jetties. Breaking waves may occasionally impact harbors making navigating the harbor channel dangerous.

Saltwater will likely splash onto low-lying coastal roads. Bays and beaches may become inundated.

Coral reefs may experience increased stress and damages, in addition to localized beach erosion, particularly in areas where battering waves focus.
