Jamaica is braced for what could be a devastating storm as Hurricane Dean blows in from the Caribbean Sea.
Residents were securing their belongings before heading inland
The island sits right in Dean's path and meteorologists warn the storm could have "potentially catastrophic" results, dumping 20in (50cm) of rain.
Low-lying areas are being evacuated and schools and churches are being converted into emergency shelters for those with nowhere else to stay.
Dean has already claimed at least six lives in the eastern Caribbean.
However, Haiti and the Dominican Republic were spared the worst of its 230km/h (145mph) winds overnight, as it passed to the south, though there was some flooding in coastal areas.
As Jamaica closed airports and imposed curfews, the US said it was prepared to fly in aid if necessary.
Areas of the Cayman Islands and Mexican coast are also being evacuated, amid meteorological reports the storm could intensify into a Category Five hurricane after it leaves Jamaica.
In the US, the return of the space shuttle Endeavour was brought forward by a day in a bid to beat the hurricane should it eventually reach Texas, where Nasa's mission control is based.
The National Hurricane Centre in Miami has warned that Dean could cause life-threatening flash floods and mudslides in Jamaica.
"Everywhere along the coast should be taking every precaution possible to save lives," spokeswoman Rebecca Waddington told the BBC's World Service.
Jamaica is on full alert. Off-duty police officers and fire-fighters have been ordered to report for duty so they can help with security and rescue operations.
Krechet Creaves, an official in Jamaica's emergency planning department, said the island was aware it could suffer a "direct hit".
"As such we have pulled out all our response agencies, we have put them on high alert," she told the BBC.
Early on Sunday morning people were still heading to hardware stores to get boarding for their houses and there were long queues at petrol stations and supermarkets.
Some areas were placed under a 48-hour curfew, which started at 1800 (2300 GMT) on Saturday.
