Eastern Tropical Atlantic (AL97):Shower and thunderstorm activity has persisted and continues to show signs of organization with a well-defined area of low pressure located just to the west of the Cabo Verde Islands. If these structural trends continue, the system is likely to become a tropical depression or storm, possibly as soon as later this morning. Locally heavy rainfall and gusty winds are expected to continue today across portions of the Cabo Verde Islands, and interests there should monitor the progress of this system. Regardless of development over the next couple of days, the system is expected to continue moving westward to west-northwestward at 15 to 20 mph across the eastern and central tropical Atlantic.* Formation chance through 48 hours...high...90 percent.* Formation chance through 7 days...high...90 percent.Central Atlantic (AL96):A weak trough of low pressure located over the central Atlantic is only producing limited shower and thunderstorm activity.
