Hurricane Dean bore down on Jamaica early yesterday amid concerns it could become "a potentially catastrophic" category five storm capable of causing death and widespread destruction.
Tourists fled resorts in the path of the storm and residents battened down as the massive swell skirted the Dominican Republic and plowed toward Jamaica, the Caymans and the Mexican coast.
A boy of 16 was reported dead and several injured in the Dominican Republic as Dean swept by to the south, sending great waves crashing onto its shores, Santo Domingo province Governor Eladio Martinez said on the radio.
Haiti ordered flights and coastal shipping suspended through yesterday and prepared to evacuate seaside regions in Dean's path as the storm appeared poised to pass next to the country at midday.
Jamaica, dead at the center of the storm's expected track, went on full alert, closing down airports, as hundreds of thousands flocked to markets and gasoline stations to stock up on essentials.
"Dean could become a potentially catastrophic category five hurricane at any time before it reaches Yukatan," the US National Hurricane Center warned in a statement issued in Miami, Florida.
Category five hurricanes can bring huge storm surges of 5.5m or more and can require the massive evacuation of areas as far inland as 10km.
Jamaican Prime Minister Portia Simpson Miller called on all off-duty police officers, firefighters and prison warders to report for work in an effort to reinforce security and rescue operations.
Curfews of 48 hours were imposed in a number of areas, mandatory evacuation of low lying and flood prone areas was ordered, and the country's two main airports in Port-Au-Prince and Montego Bay were closed.

Quintana Roo Governor Felix Gonzalez ordered the evacuation of the 80,000 tourists from Cancun and other popular barrier islands of the "Mayan Riviera" and blocked the further arrival of more tourists to the area.
"We can evacuate 30,000 tourists by air every day. That gives us enough time to leave hotel occupancy at a minimum, with a reasonable number of guests we can assist and put up in shelters" when the storm strikes, Gonzalez said.
