A tropical depression has formed over the Eastern Atlantic Ocean.

According to the National Hurricane Centre, the system is expected to stay over water for many days, currently moving west-northwest near 30 km/h.

Some strengthening is forecast during the next 48 hours, and Tropical Depression Seven could become a tropical storm tonight or on Thursday.

It currently poses no hazard to land.

Two other weather systems, AL92 and AL94 are closer to the Caribbean, but both have been given a low chance for development.

Central Tropical Atlantic (AL92)
An elongated area of low pressure located over the central tropical Atlantic continues to produce some disorganized shower and thunderstorm activity. Environmental conditions appear marginally conducive for some slight development during the next day or two while the system moves westward at 5 to 10 mph over the central tropical Atlantic. The disturbance is expected to reach an area of stronger upper-level winds on Thursday, likely ending its chances for development.

* Formation chance through 48 hours…low…30 percent.
* Formation chance through 7 days…low…30 percent.

East of the Leeward Islands (AL94)
A small but well-defined area of low pressure located several hundred miles to the east of the Leeward Islands is producing an area of disorganized showers and thunderstorms. The proximity of dry air near the system is expected to limit additional development over the next couple of days before environmental conditions become even less conducive by this weekend as it moves slowly west-northwestward.

* Formation chance through 48 hours…low…10 percent.
* Formation chance through 7 days…low…10 percent.
