A tropical wave that is producing disorganized showers and thunderstorms is forecast to move off the west coast of Africa today and make its way further west into the Atlantic Ocean.

Environmental conditions are expected to be conducive for gradual development of this system while it moves generally westward to west-northwestward at 15 to 20 mph across the eastern and central tropical Atlantic during the early to middle part of next week.

The wave has a 40 percent chance of formation in the next 7 days, the NHC says.
