In an early taste of what could be coming, the fury of Hurricane Wilma is being felt along Mexico’s popular Caribbean beach resorts.
As well as flooding, many trees have been knocked over.
The category four hurricane is moving in slowly from the Caribbean, its winds and torrential rain gathering strength.
Forecasters are warning there could be catastrophic damage.
Cuba is also starting to feel the force of Wilma, and the storm’s expected to hit densely-populated southern Florida on Sunday.
Authorities in Cuba have evacuated more than 350,000 people from low-lying areas and unstable buildings.
People are also stocking up on food and water, with fears that some areas could be cut off for weeks.
Mudslides caused by Wilma have already killed at least 10 people in Haiti.
The hurricane’s expected to miss Gulf of Mexico oil and gas facilities that were battered by hurricanes Katrina and Rita in August and September.
