Data from a NOAA aircraft reconnaissance mission earlier today showed little change in organization of the area of low pressure located several hundred miles east of the Lesser Antilles.

Although environmental conditions are only marginally conducive, additional gradual development of this system is expected and a tropical depression is likely to form within the next couple of days.

The disturbance is forecast to move slowly west-northwestward, toward the adjacent waters of the northern Leeward Islands.

* Formation chance through 48 hours…medium…60 percent
* Formation chance through 5 days…high…80 percent

Eastern Tropical Atlantic:

Showers and thunderstorms associated with a broad area of low pressure located just to the northeast of the Cabo Verde Islands have changed little since earlier today.

Some gradual development is possible, and the system could become a short-lived tropical depression over the far eastern Atlantic during the next couple of days.

By late this week, environmental conditions are forecast to become increasingly unfavorable for further development.

Regardless, the system could bring locally heavy rainfall to portions of the Cabo Verde Islands through Thursday.

* Formation chance through 48 hours…medium…40 percent
* Formation chance through 5 days…medium…40 percent

Central Sub-Tropical Atlantic:

An area of low pressure is showing signs of organization over the central subtropical Atlantic about 850 miles west-southwest of the westernmost Azores.

Environmental conditions are expected to be conducive for development, and a tropical or subtropical depression is likely to form within the next day or so, while the system drifts generally eastward.

* Formation chance through 48 hours…high…70 percent
* Formation chance through 5 days…high…80 percent
