Shower and thunderstorm activity associated with an elongated area of low pressure located several hundred miles east of the Lesser Antilles has increased since yesterday.

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 few days.

The disturbance is forecast to move slowly toward the west and then west-northwest at 5 to 10 mph, 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:

A broad area of low pressure located off the west coast of Africa is producing disorganized showers and thunderstorms.

Some gradual development is possible, and the system could become a short-lived tropical depression over the far eastern Atlantic during the next few 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 on Wednesday and Thursday.

* Formation chance through 48 hours…low…20 percent
* Formation chance through 5 days…medium…40 percent

Central Sub-Tropical Atlantic:

An area of low pressure is expected to form within the next day or so along a decaying frontal zone over the central subtropical Atlantic.

Environmental conditions are expected to be conducive for some gradual tropical or subtropical development over the next several days while the system drifts generally eastward.

* Formation chance through 48 hours…low…10 percent
* Formation chance through 5 days…low…30 percent
