A tropical wave is producing a large area of disorganized showers and thunderstorms over the far eastern Atlantic between the Cabo Verde Islands and the west coast of Africa. Environmental conditions appear conducive for some gradual development of this system, and a tropical depression could form later this week or this weekend while the system moves west-northwestward at 10 to 15 mph
over the eastern tropical Atlantic. This system is expected to move
across the Cabo Verde Islands tonight and Thursday, and interests there should monitor its progress.
