The hurricane’s intensity shocked forecasters, who had predicted just 16 hours before landfall that Otis would come ashore as a Category 1 storm. Satellite images captured at 2:30 a.m. on Tuesday show Otis located 210 miles south-southeast of Acapulco—still a tropical storm with winds at about 65 miles per hour. But by 12:25 a.m. on Wednesday, Otis had become the strongest hurricane to ever hit Mexico’s Pacific Coast and the fastest-strengthening storm on record in the northeastern Pacific Ocean.
