The wave west of 90L is now Invest 91L.
A broad area of low pressure located several hundred miles southwest of the Cabo Verde Islands is producing a large area of disorganized showers and thunderstorms. Environmental conditions are conducive for further development, and a tropical depression is likely to form during the next day or two while the system moves westward to west-northwestward at 5 to 10 mph over the central tropical Atlantic.
* Formation chance through 48 hours...high...70 percent. * Formation chance through 5 days...high...90 percent.

Showers and thunderstorms remain disorganized in association with a a broad area of low pressure located several hundred miles southwest of the Cabo Verde Islands. Environmental conditions are conducive for gradual development, and a tropical depression could still form during the next couple of days if the disturbance does not get absorbed into the stronger low pressure system located to its east. The broad low is expected to move slowly west-northwestward to westward over the central tropical Atlantic during the next few days.
* Formation chance through 48 hours...medium...60 percent. * Formation chance through 5 days...medium...60 percent.

Showers and thunderstorms remain disorganized in association with a a trough of low pressure located several hundred miles southwest of the Cabo Verde Islands. Development of this system appears less likely due to the interaction with the larger low pressure area located to its east. The system is forecast to drift west-northwestward over the tropical central Atlantic during the next few days.
* Formation chance through 48 hours...low...30 percent. * Formation chance through 5 days...low...30 percent.
