However, environmental conditions still appear to be conducive for development and a tropical depression is expected to form within the next few days while the system moves toward the west or west-northwest across the tropical Atlantic Ocean.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...90 percent.
The X is where a tropical wave is forecast to move off the west coast of Africa on Friday.
