Tropical Storm Fiona has intensified and is now heading toward the Dominican Republic and Puerto Rico, where hurricane warnings are in place.
It threatens to throw up to 41 cm of rain over parts of Puerto Rico as locals brace for potential landslides, severe flooding and power outages.
Authorities opened shelters and closed public beaches, theaters and museums as they urged people to stay at home.
Fiona is expected to pass through the Dominican Republic on Sunday as a potential hurricane and Haiti and the Turks and Caicos Islands on Monday and Tuesday with a risk of heavy rain.
On Friday, it swept through Guadeloupe, killing a man whose home was swept away by a flood when a nearby river inundated. The island was put on high alert for heavy rains and storms, and its residents were prepared.
Schools were closed as the island was hit by 120km/h winds and 23cm of rain in just three hours.
So far this hurricane season, seven named storms have formed in the Atlantic basin, two of which, Danielle and Earl, have reached hurricane status.
