Hurricane Rosa is a formidable hurricane in the eastern Pacific, but its greatest impact will likely be as a remnant bringing a threat of flash flooding to the southwestern United States early next week.
Rosa became a hurricane Wednesday morning in the eastern Pacific Ocean just under 500 miles south-southwest of Cabo San Lucas, Mexico.
Rosa rapidly intensified into a major hurricane Thursday afternoon and is now a Category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Rapid intensification is defined as an increase in maximum sustained winds of at least 35 mph in 24 hours or less. Rosa has nearly doubled that rate of intensification.
Rosa is the seventh Category 4 hurricane of the 2018 eastern Pacific Hurricane Season, tying the record recently set in 2015.
