(CNN) -- Hurricane Celia strengthened to a Category 5 storm in open waters in the Pacific on Thursday, but it did not pose a threat to land, forecasters said.
The National Hurricane Center said Celia showed maximum sustained winds of 160 mph (260 kph) and was about 785 miles (1,260 km) southwest of the southern tip of Baja California at 8 p.m. PDT (11 p.m. ET).
The storm, which was moving northwest farther out to sea, will likely weaken during the next two days, the center said.
Forecasters describe hurricane intensity using the Saffir-Simpson Hurricane Wind Scale, ranking storms from 1 to 5. Category 5 storms are the strongest hurricanes, with sustained winds greater than 155 mph.
