Forecasters say Hurricane Fabio has strengthened over the Pacific but will not threaten land.

The National Weather Service in Miami says Fabio has maximum sustained winds of 105 mph (169 kph) and is about 575 miles (925 kilometers) south-southwest of the southern tip of Mexico's Baja California. It is moving northwest.

Fabio is expected to start weakening late Saturday or early Sunday.

Meanwhile, Tropical Storm Emilia, farther out in the Pacific, is moving westward and is expected to continue weakening.
