Hurricane Dean slammed into the Caribbean coast of Mexico on Tuesday as a roaring Category 5 hurricane, the most intense Atlantic storm to make landfall in two decades. It lashed ancient Mayan ruins and headed for the modern oil installations of the Yucatan Peninsula.

Dean's path was a stroke of luck for Mexico: It made landfall in a sparsely populated coastline that had already been evacuated, skirting most of the major tourist resorts. It weakened within hours to a Category 2 storm, with maximum sustained winds of 105 mph.

The eye of the storm hit land near Majahual, a port popular with cruise liners, and it was racing across the Yucatan Peninsula toward a Tuesday afternoon entry into the Bay of Campeche, where the state oil company evacuated the oil rigs that produce most of Mexico's oil.

In the largely Mayan town of Felipe Carrillo Puerto, at one point about 30 miles from the center of the storm, people stared from their porches at broken tree limbs and electrical cables crisscrossing the streets, some of which were flooded with ankle-deep water.

Tin roofing ripped from houses clunked hollowly as it bounced in the wind whistling through town.

"We began to feel the strong winds about 2 in the morning and you could hear that the trees were breaking and some tin roofs were coming off," said Miguel Colli, a 36-year-old store employee. "Everyone holed up in their houses. Thank God that the worst is over."
