Cabo San Lucas - Hurricane Blanca, a Category-4 storm, is spinning in the eastern Pacific Ocean. The storm's maximum sustained winds reached 220 kilometers (140 miles) per hour and it was "barely moving" some 745 kilometers (465 miles) southwest of Zihuatanejo, Guerrero, Mexico, the US National Hurricane Center said Wednesday afternoon.

Blanca may be nearly stationary, but it will begin moving northwestward Thursday, the Weather Channel said. There is increasing confidence in a track toward southern Baja California, though it is expected to weaken as comes closer to land.

"Swells generated by Blanca will begin affecting portions of the coast of southwestern Mexico during the next couple of days," the hurricane center said. "These swells are likely to cause life-threatening surf and rip current conditions."

The US National Hurricane Center's five-day tracking map shows Blanca touching the southern tip of Baja California peninsula as a tropical storm on Monday.

Blanca is the second major hurricane to form in eastern Pacific this year. A major hurricane is one that's a Category 3, 4 or 5 on the Saffir-Simpson Scale of Hurricane Intensity.

Tropical Storm Andres, which had been a major hurricane a few days ago, has decreased to near 60 mph with continued weakening expected. The storm is centered about 1,015 miles west-southwest of the southern tip of Mexico's Baja California peninsula. It's no threat to land.
