Atlantic Low-Pressure System east of the Lesser Antilles

The Trinidad and Tobago Meteorological Service (TTMS) has been closely monitoring a broad area of low pressure associated with a Tropical Wave, located approximately 2200 km east of the Lesser Antilles.  

As showers and thunderstorms associated with this system remain disorganized, there is a medium chance (60%) of development into a Tropical Cyclone over the next 48 hours and a slightly higher chance (70%) of development in five (5) days, as environmental conditions become more favourable.  

This low pressure system is forecast to move westward to west-northwestward near 30 km/hr over the next several days (refer to figure 1). Regardless of development, the system is likely to affect portions of the Leeward islands with localized heavy rainfall and gusty winds by early next week.  

At this time, the system poses no direct threat to Trinidad, Tobago, Grenada and its dependencies.


The TTMS will continue to closely monitor this system and will issue an update at 6:00 pm today, Friday 17th September, 2021 or earlier if the situation warrants. As always, pay close attention to information being issued by the TTMS by visiting, downloading our mobile app (search: TT Met Office) and following us on Twitter, Facebook and Instagram.
