Hurricane Emilia formed in the eastern Pacific early Monday and is expected to become a major hurricane sometime Tuesday, the National Hurricane Center said.
At 2 a.m. PT, the Category One storm with maximum sustained winds of 75 mph was about 760 miles south of the southern tip of Baja California and moving west-northwest at 12 mph, forecasters said.
Emilia is strengthening rapidly and is forecast to become a Category Two storm later on Monday and a Category Three, or major hurricane, with maximum sustained winds above 111 mph, on Tuesday, the hurricane center said.
Emilia posed no threat to land, however, and no coastal watches or warnings are in effect.
Emilia is the fourth Pacific hurricane of the season. Hurricane Daniel formed Friday and early Monday was a strong Category One storm with maximum sustained winds of 90 mph.
Daniel was about 1,270 miles west-southwest of the southern tip of Baja and moving west at 15 mph.
It was expected to weaken to tropical storm status sometime Monday as it encounters colder waters in the Pacific.
Daniel also posed no threat to land.
