MIAMI, June 9 (UPI) -- Hurricane Adrian was classified as a Category 4 storm but remained well off the Pacific Coast of Mexico Thursday, forecasters said.
At 3:30 p.m., the National Hurricane Center in Miami said Adrian was about 320 miles off Manzanillo, Mexico, with top sustained winds of 135 mph. The hurricane was moving toward the west-northwest at 9 mph and was expected to continue on that general motion for another 48 hours.
Additional strengthening was possible Thursday night and Friday, with some gradual weakening after Friday.
Swells generated by the storm were expected to affect part of the southwestern coast of Mexico through the early weekend, forecasters said. It was possible the swells could cause life-threatening surf and rip currents.
