The Caribbean is set to be belted by another hurricane, less than 2 weeks after Irma carved her deadly path of destruction.
The powerful storm, named Hurricane Maria, is currently bearing down on a string of battered Caribbean islands, with forecasters saying it's still getting stronger. The system is about 400km east-southeast of the Leeward island of Dominica.
Winds are expected to accelerate to 193km/h within 72 hours, by which time the hurricane could reach the British and US Virgin Islands and Puerto Rico.
The government of Puerto Rico has already begun preparations for Maria, which is expected to make landfall on Tuesday.
Hurricane Irma hammered the region less than a fortnight ago, before overrunning Florida. That powerful Category 4 storm killed at least 84 people, more than half of them in the Caribbean.
The United Nations is launching a $US5.7 million operation in Cuba to help feed nearly 700,000 people in areas most affected by that storm, which ripped up the Caribbean's largest island, tearing off roofs, wrecking the power grid and damaging crops.
