In the capital Kingston, supermarkets were crowded with people looking for canned food, water and flashlights.

"It has been chaos from morning," said Melain Azan, a shopkeeper.

"We have been (selling an) unbelievable amount of kerosene lamps, flashlights, battery radios, plastic containers, tarpaulins, candles - you name it."

Officials have warned the high winds could batter Jamaica's main tourist areas including Montego Bay in the north.

In Haiti, the poorest country in the Americas, residents from outlying islands have been evacuated, and officials have banned boating.

The hurricane is expected to cause up to 101 cm (40 inches) of rain there.

Matthew is expected to hit Cuba on Tuesday, potentially reaching the colonial city of Santiago de Cuba and the US Navy base of Guantanamo Bay.

An evacuation of non-essential personnel was under way at the base and everyone remaining there was being told to take shelter, the Navy said in a statement.

There are about 5,500 people living on the base, including 61 men held at the detention centre.

Cuban President Raul Castro travelled to Santiago to supervise preparations.

Matthew is the strongest storm in the region since Hurricane Felix in 2007. It briefly reached the top category five on a scale of intensity, before weakening slightly.
