A tropical wave that pushed off the western coast of Africa behind Tropical Storm Gabrielle is located a few hundred miles east-southeast of the Cabo Verde Islands and is currently producing an area of disorganized showers and thunderstorms.

The NHC said that environmental conditions are only marginally conducive for further development, and if development were to occur, it would be slow.

Regardless of development, the system will produce areas of heavy rain across the Cabo Verde Islands on Wednesday and Thursday.

The system currently has a low chance of development over the next seven days.

The Atlantic hurricane season runs from June 1 through Nov. 30.
