Barbados is now under a tropical storm warning.
The Meteorological Office says the strong tropical wave east-southeast of Barbados has been upgraded to Potential Tropical Cyclone number two.
The system is expected to move westward to west-northward over the next several hours, and on this track, the centre is expected to pass about 180 miles to the south of Barbados late Monday into Tuesday.
However, sustained surface winds of 45 to 55 miles per hour with higher gusts on the northern periphery of the potential storm are expected to affect Barbados.
Rainfall accumulations of two to four inches are possible.
The Met Office says some flash-flooding is likely in low-lying areas and residents are urged to be on the alert and take the necessary precautions.
