Tropical Storm Eugene is churning the waters of the Pacific Ocean off the west coast of Mexico.

The U.S. National Hurricane Center in Miami, Florida says the storm is about 675 kilometers south-southwest of Acapulco.

Eugene is moving to the west-northwest at about 17-kilometers per hour with sustained winds of 75-kilometers per hour. Tropical storm force winds extend 110 kilometers from the storm's center.

Eugene is expected to become a hurricane by Tuesday, but remain far from land.
