A cluster of storms in the northern Caribbean headed toward the Bahamas on Saturday as meteorologists warned it could soon strengthen into a tropical depression or a tropical storm.
The National Hurricane Center said the storm was moving west-northwestward and would pass over or near the southeastern Bahamas. It was still generating heavy rains and wind over parts of Haiti, the Dominican Republic and Puerto Rico.
The storm is expected to also unleash heavy rains over the Turks and Caicos islands and had an 80 percent chance of becoming a tropical storm by late Saturday or Sunday.
The system previously downed several trees and power lines in Puerto Rico, as well as leaving thousands of people without power or water.
The storm is expected to move near or across the central Bahamas on Sunday.
