It is located about 390 miles (625 km) west-southwest of Bermuda and is moving north at 8 mph (13 kph). The storm is expected to turn toward the northeast later Thursday, and the center is expected to pass northwest of Bermuda on Friday morning.
Forecasters say Sean could become a hurricane later Thursday before weakening on Friday.
