A new hurricane - named "Darby" - formed today in the Pacific off Mexico's southwest coast, while Hurricane Celia strengthened farther out at sea.
Neither hurricane posed an immediate threat to land.
Darby, a Category 1 hurricane with winds of 130 kph, was located about 320 km south-southwest of Puerto Escondido on Thursday afternoon, according to the National Hurricane Centre in Miami.
It was expected to strengthen over the next two days as it heads west-northwest, well away from land.
The hurricane centre projected the storm could take a sudden eastward turn early next week, putting it on a path toward Mexico's southern Pacific coast.
Meanwhile, Celia became a Category 4 hurricane as it headed west across the open Pacific. Its maximum sustained winds increased to 215 kph.
It was located about 1200 km off the southern tip of Mexico's Baja California peninsula.
