MIAMI (AP) - Hurricane Bill has become a dangerous Category 4 storm as it howls through the open Atlantic's energizing waters.
Forecasters say Bill should begin pushing large swells toward Bermuda and parts of the southeastern U.S. coast by the weekend. But it's not yet clear how close the storm will come to land.
The five-day forecast predicts its center will pass well offshore of the North Carolina-Virginia line Sunday.
The Atlantic's waters are expected to continue boosting the storm's power as it moves north.
Bill is maintaining a top wind speed of 135 mph and is centered about 380 miles east of the Leeward Islands -- or more than 1,500 miles southeast of Miami. It is moving west-northwest near 18 mph.
