Formation chance through 7 days is also low at 10 percent.
In the Eastern Tropical Atlantic, another tropical wave is forecast to move off the west coast of Africa tonight or early Wednesday. Some slow development of this system is possible this week or over the weekend while it moves west-northwestward or northwestward across the eastern Atlantic. Environmental conditions are then expected to be less favorable for development.
