The meteorological history of Hurricane Dean began in the second week of August 2007 when a vigorous tropical wave moved off the west coast of Africa into the North Atlantic basin. Although the wave initially experienced strong easterly wind shear, it quickly moved into an environment better suited for tropical development and gained organization. On the morning of August 13, the National Hurricane Center recognized the system's organization and designated it Tropical Depression Four while it was still more than 1,500 mi (2,400 km) east of the Lesser Antilles.

A deep layered ridge to its north steered the system west as it moved rapidly towards the Caribbean and into warmer waters. On August 14 the depression gained strength and was upgraded to Tropical Storm Dean. By August 16, the storm had intensified further and was granted hurricane status. Hurricane Dean continued to intensify as it tracked westward through the Lesser Antilles. Once in the Caribbean Sea the storm rapidly intensified to a Category 5 Hurricane. Weakening slightly, it brushed the southern coast of Jamaica on August 19 as a Category 4 Hurricane and continued towards the Yucatán Peninsula through even warmer waters. The favorable conditions of the western Caribbean Sea allowed the storm to intensify and it regained Category 5 status the next day. It was one of two storms in the 2007 Atlantic hurricane season to make landfall as a Category 5 Hurricane and was the seventh most intense Atlantic hurricane ever recorded, tied with Camille and Mitch.

After its first landfall, Hurricane Dean crossed the Yucatán Peninsula and emerged, weakened, into the Bay of Campeche. It briefly restrengthened in the warm waters of the bay before making a second landfall in Veracruz. Dean progressed to the northwest, weakening into a remnant low which finally dissipated over the southwestern United States.
