At least 12 people were killed as two storms tore through the Caribbean on Sunday.
Hurricane Marco and Tropical Storm Laura brought high winds and rough seas leaving at least nine people dead in Haiti and another three in the Dominican Republic.
Heavy rains have also battered Cuba and the US territory of Puerto Rico.
Marco is expected to make landfall in the US state of Louisiana on Monday, with Laura hitting Texas by Thursday.
The US National Hurricane Center (NHC) said that Laura was expected to strengthen into a hurricane by early Tuesday.
Forecasters also say that Laura may swing east towards Louisiana, and it could be the first time in recorded history that the state has been hit by two back-to-back hurricanes.
In total, 200 homes were damaged in the Dominican Republic and 1,000 people had to be evacuated.
Meanwhile in Cuba, many residents in the country’s eastern regions have been evacuated and housed in shelters or safer buildings on higher ground.
US President Donald Trump has issued a disaster declaration for Louisiana, ordering federal assistance to coordinate relief efforts. On Saturday, a similar declaration was made for Puerto Rico.
