KINGSTON, Jamaica (AP) — Hurricane Matthew is roaring across the Caribbean Sea as a monster Category 5 storm on a course that puts Jamaica, as well as parts of Haiti and Cuba, in the path of its potentially devastating winds and rain. Jamaicans began clearing out store shelves as they stocked up emergency supplies and Prime Minister Andrew Holness on Friday called an urgent meeting of Parliament to discuss preparations for the storm. Matthew was expected to bring heavy rainfall especially to the eastern tip and higher elevations, which could trigger flooding and landslides, Thompson said. The government issued a hurricane watch on Friday, and a tropical storm watch was issued for Haiti's southwest coast form the southern border it shares with the Dominican Republic to the capital of Port-au-Prince.
