A new tropical depression has formed far out over the Atlantic with forecasters saying it will likely become a tropical storm.
The depression's maximum sustained winds early Thursday are near 35 mph (55 kph). But the U.S. National Hurricane Center in Miami says additional strengthening is expected and it's likely to become a tropical storm later in the day.
The depression is centered about 435 miles (700 kilometers) west-southwest of the southernmost Cape Verde Islands and is moving west-northwest near 13 mph (20 kph).
Meanwhile farther west, Hurricane Irene is threatening the U.S. East Coast.
