Costa Maya

Hurricane Dean passed south of Jamaica on the evening of August 19[27] and began to intensify again that night.[28] Its eyewall replacement cycle was thought to be completed.[29] A concentric eyewall was briefly observed again on the morning of August 20, but did not last long. The hurricane, still tracking west-northwest under the influence of a strengthening deep-layered high pressure system to the north, moved over waters with extremely high heat content and began to strengthen once again.[30] The eyewall became even better defined during the day,[31] and, at 8:35 p.m. AST on August 20 (0035 August 21, UTC), Dean restrengthened to a Category 5 hurricane, the highest rating on the Saffir-Simpson Hurricane Scale.[32] It made landfall as a Category 5 storm in Quintana Roo's Costa Maya region, 40 mi (65 km) northeast of the border between Mexico and Belize, and weakened on its way over land, reemerging on the western side of Yucatán as a Category 1 storm.[33] Dean regained strength as it crossed the Gulf of Mexico, and made its second landfall as a Category 2 storm on August 22, at around 11:30 CDT, near Tecolutla, Veracruz, to the south of Tuxpan, where after it moved westward, losing strength and disintegrating over central Mexico. A small remnant circulation reached the Pacific Ocean,[34] eventually moving northwestward around an anticyclone, roughly parallel to the Mexican coast and finally back inland over the southwestern United States,[35] where it completely dissipated on August 27.[36]
