SAN JUAN — Two tropical wave has a medium chance of formation in the next seven days in the far eastern and central Atlantic.
Disorganized showers and thunderstorms located over the central tropical Atlantic are associated with an elongated trough of low pressure centered about 750 miles west-southwest of the Cabo Verde Islands.
Environmental conditions appear conducive for gradual development of this system, and a tropical depression could form during the next several days while moving toward the west or west-northwest at about 10 mph across the central tropical Atlantic.
* Formation chance through 48 hours…low…30 percent.
* Formation chance through 7 days…medium…50 percent.
