Rosa, which is now a Category 3 storm, weakened slightly off Mexico’s Pacific Coast on Friday. The storm had maximum sustained winds of 120 mph and was located 625 miles southwest of the southern tip of Baja California as of Friday evening. It was moving west at 6 mph.

It is expected to become a tropical storm by late Sunday as it heads northeast toward the Baja California peninsula. The hurricane center said there were no coastal watches or warnings in effect, but swells generated by Rosa were expected to cause dangerous surf and rip current conditions along portions of southwestern Mexico, the peninsula and southern California.

Remnants of the Rosa are expected to hit Arizona on Sunday, bringing heavy rain, high winds and the threat of localized flooding, the National Weather Service said. Forecasters say up to 4 inches could fall in some areas through Wednesday, including Flagstaff, Payson, Prescott and the Grand Canyon’s South Rim. The North Rim could see up to 6 inches.
