Forecasters monitoring 3 systems in Atlantic for development

A tropical wave formed Tuesday south of the Lugar Verde Islands off the coast of Africa, bringing the tally of disturbances in the Atlantic Ocean to three, the National Hurricane Center said.

The system off of Africa has a 20% chance of developing over the next seven days as it travels westward to west-northwestward over the tropical Atlantic.

A second tropical wave over southeastern Caribbean Sea is producing disorganized showers and thunderstorms, with some locally heavy rains, but it is not expected to develop any further, forecasters said in an 8 p.m. update.

A third system east of the Bahamas will move toward the U.S. over the next several days, the National Hurricane Center said.

It has a near 0% chance of forming in the next two days and a 10% chance in the next seven days, the center said in its 8 p.m. update. It is unlikely to significantly develop.

National Weather Service meteorologist Barry Baxter said the system will likely veer north and not affect South Florida.

An upper-level low in the Caribbean is likely to bring moisture and strong thunderstorms to the Sunshine State in the coming days.
