Tropical Storm Genevieve has strengthened into a hurricane far off Mexico's Pacific coast, and forecasters say it is expected to stay out at sea.

The National Hurricane Center in Miami says Genevieve was 585 miles southwest of Cabo San Lucas in Baja, Calif., and was moving west-northwest at about 12 mph with winds clocked at 75 mph.

Forecasters say the storm will likely reach its peak intensity Friday and then start to weaken by Saturday. Genevieve is the fourth Pacific hurricane of the season.
