Hurricane Calvin was one of three Pacific hurricanes on record to make landfall along the Mexican coast during the month of July. The fourth tropical cyclone, third named storm, and second hurricane of the 1993 Pacific hurricane season, Calvin developed from an area of convection to the south of Mexico on July 4. The following day, the system intensified into a tropical storm, which was named Calvin. Continued strengthening ensued as Calvin curved from its initial westward track northward, and was upgraded to a hurricane on July 6. Calvin eventually turned northwest, and became a Category 2 hurricane on the Saffir–Simpson hurricane wind scale (SSHWS). By July 7, Hurricane Calvin made landfall near Manzanillo at peak strength. Calvin rapidly weakened after landfall, and was a tropical storm when it reemerged into the Pacific Ocean on early on July 8. Despite this, the hurricane did not reintensify, and continued to weaken as it headed rapidly northwestward. As Calvin made a second Mexican landfall near the southern tip of Baja California peninsula late on July 8, it weakened to a tropical depression. Early on July 9, the depression dissipated shortly after entering the Pacific Ocean for a third time.
Calvin was only the third July hurricane on record to make landfall on the west coast of Mexico. Throughout the nation of Mexico, Calvin dropped heavy rainfall, especially in the southwestern portion of the country. Heavy rainfall produced flooding, which, in turn, caused mudslides. In the wake of Calvin, 37 fatalities were reported. Most of the casualties were due to flooding or car accidents. In the state of Michoacán, 700 homes were destroyed. In addition, a 15-foot (4.6 m) storm surge was reported. Many boats and shoreline structures from Acapulco to Manzanillo were damaged. Heavy seas near Lázaro Cárdenas in western Mexico caused a ship, which contained sulfuric acid, to leak. The cleanup effort took one month to complete. In all, 30,000 people were displaced by the storm. Overall, Calvin caused $32 million (1993 US$) in damage.
