Hurricane Cosme (KAHS'-may) has strengthened to its likely peak intensity in the Pacific Ocean well off the coast of Mexico.
The hurricane had top sustained winds of 85 mph (137 kph) late Tuesday. Forecasters say the storm will gradually weaken Wednesday and Thursday.
The U.S. National Hurricane Center in Miami says Cosme is centered about 410 miles (660 kilometers) south-southwest of Cabo San Lucas, Mexico, and is moving west-northwest at 14 mph (28 kph).
The center says the storm is generating large swells that are affecting parts of Mexico's Pacific coast and its Southern Baja California Peninsula. The swells are likely to cause dangerous surf and rip current conditions.
No coastal watches or warnings are in effect.
