Tropical Storm Fiona has strengthened and is now heading towards the Dominican Republic and Puerto Rico where hurricane warnings are in effect.
It threatens to drop up to 16 inches of rain on parts of Puerto Rico and where locals are bracing for potential landslides, severe flooding and power outages.
Authorities opened shelters and closed public beaches, theaters and museums while urging people to stay indoors.
Fiona is expected to pass the Dominican Republic on Sunday as a potential hurricane and Haiti and the Turks and Caicos Islands on Monday and Tuesday with the threat of heavy rain.
It hit Guadeloupe on Friday, killing a man who was swept away with his house when a nearby river overflowed. A red alert was placed on the island due to heavy rains and storms, and its residents were prepared.
Schools were closed because the island was hit with winds of 120 km/h and 23 cm of rain fell in just three hours.
So far this cyclone season, seven named storms have formed in the Atlantic basin, two of which, Danielle and Earl, have reached hurricane status.
