Hurricane Calvin (1993)

Hurricane Calvin (1993)

Hurricane Calvin was one of three Pacific hurricanes to make landfall in 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. On the following day, the system intensified into a tropical storm, which was named Calvin. Continued strengthening occurred as Calvin turned northward, after originally heading westward. As Calvin was turning northward, it was upgraded to a hurricane on July 6. Calvin eventually turned northwest, and became a Category 2 hurricane. By July 7, Calvin made landfall near Manzanillo as a Category 2 hurricane. Calvin rapidly weakened after landfall, and was a tropical storm when it re-emerged into the Pacific Ocean on early on July 8. Despite this, Calvin did not re-intensify, and instead weakened as it headed rapidly northwestward. As Calvin made a second Mexican landfall near the southern tip of Baja California Peninsula on July 8, it weakened to a tropical depression. Early on July 9, Calvin dissipated shortly after again emerging into the Pacific Ocean.

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 regions. Heavy rainfall produced flooding, which, in turn, caused mudslides. In the wake of Calvin, 34 fatalities were reported, a majority of which, were as a result of the flooding and mudslides. In addition, during the flooding caused by Calvin, 700 houses were destroyed in the state of Michoacán. Overall, Calvin caused (1993 USD; $51.5 million 2012 USD) in damage.
