Calvin continued to intensify, and reached hurricane status on July 6 after a turn to the north. The storm became embedded within a large, monsoon-like deep layer circulation, allowing Calvin to continue northwestward while increasing in size. The eyewall contracted to around 10 miles (20 km) wide, and the hurricane reached its peak of 110 mph (180 km/h) on July 7. After paralleling the Mexican coastline for a day, Calvin hit western Mexico near Manzanillo late on the 7th. Calvin, though over land for about 6 hours, rapidly weakened over the mountainous terrain to a large and disorganized 70 mph (113 km/h) tropical storm. It continued
