In Jamaica, at least 28 people have died and according to the country's Prime Minister Andrew Holness, "there are additional reports of possible deaths that are still being investigated."
The storm that hit Jamaica on Tuesday is the worst to hit the country in 90 years. In the western parts of the country, the devastation is extensive and several communities have been completely cut off.
Homes, hospitals, business buildings and other buildings have been severely damaged or destroyed.
It is estimated that Melissa could cause economic losses equivalent to Jamaica's annual GDP, says Nahuel Arenas, head of the UN Office for Disaster Risk Reduction in the Americas and the Caribbean.
In Haiti, at least 31 people have died, including ten children who drowned in the heavy flooding. Melissa also swept over parts of Cuba and the Dominican Republic.
