Active Tropical Wave In Central Tropical Atlantic — Met Office Issues First Official Statement
UPDATE (11/08/26): In its second and final official statement, the Trinidad and Tobago Meteorological Service (TTMS) said it continues to monitor a Tropical Wave located approximately 1,300 Km East of the Windward Islands. At this time (Tuesday 11th August, 2026), the system is no longer expected to become more organized, and it now has a 0% chance of developing into a Tropical Cyclone over the next seven (7) days.
The Tropical Wave is being affected by a moderate concentration of Saharan dust that is limiting the potential for development of strong and organized thunderstorms. “Notwithstanding this, the TTMS will continue to monitor the Wave as it moves Westward, and assess its possible influence on local weather conditions. This will be the final official statement regarding the potential for Tropical Cyclone development associated with this system. The TTMS will continue to monitor the Tropical Wave through its routine forecasting operations.”
The Trinidad and Tobago Meteorological Service (TTMS) said it has been monitoring an active Tropical Wave in the Central Tropical Atlantic, centred approximately 1,900 Km East of the Southern Windward Islands.
At this time today (Monday 10th August, 2026), the system is disorganized with scattered patches of showers and thunderstorms.
The Met Office notes that there is a low (10%) chance of development of a Tropical Cyclone over the next two (2) to seven (7) days. The Wave is moving Westward at approximately 28 Km/h and is expected to affect the Southern Windward Islands from Thursday (13th August, 2026) of this week.
THERE ARE CURRENTLY NO WATCHES OR WARNINGS IN EFFECT FOR TRINIDAD AND TOBAGO.
The TTMS said it will issue an update to this statement at 2:00 PM tomorrow (Tuesday 11th August, 2026), or earlier, if there are significant changes in the forecast.
Meanwhile, in its 2:00 PM update this afternoon (Monday 10th August, 2026), the National Hurricane Center (NHC) in Miami said the following: “Disorganized showers and thunderstorms associated with a Tropical Wave are located about midway between the coast of West Africa and the Lesser Antilles. Some gradual development of this system is possible through mid-week while it moves quickly Westward across the Central Tropical Atlantic. Environmental conditions are expected to become less favorable for development later this week as the system approaches the Lesser Antilles.”
