MIAMI >> Hurricane Celia has been upgraded to a Category 4 storm, but it’s swirling far out over the Pacific Ocean and doesn’t immediately threaten land.

The U.S. Hurricane Center in Miami says Celia was packing winds at 135 mph as it churned up seas Thursday afternoon about 765 miles off the southern tip of Mexico’s Baja California peninsula. Celia was moving farther out to sea to the west at about 12 mph.

Meanwhile, Hurricane Darby was still swirling off Mexico’s coast and also didn’t immediately threaten land. The Category 1 storm was packing winds of about 80 mph. It was moving to the west-northwest at about 8 mph.

Forecasters said Darby could take a sudden eastward turn early next week toward Mexico’s southern Pacific coast, but warned that prediction was tentative.
