Tropical Storm Humberto strengthened from a tropical cyclone after forming just east of the Caribbean nation on Friday. Forecasters said it could become a hurricane by Sunday night.
The National Hurricane Center said in its 8 a.m. bulletin that the storm was about 30 miles east northeast of Grand Abaco Island and about 145 miles east of Freeport Grand Bahama Island, moving at about 7 mph.
Parts of the northwestern Bahamas are expected to experience tropical storm-force winds and heavy rain over the weekend, but not significant storm surge.
Most of northwestern Bahamas has a tropical storm warning in effect. Forecasters said the Bahamas will get 2 to 4 inches of rain through Monday.
Portions of the coasts of Florida and Georgia will see 1 to 2 inches of rain. However, it is not expected to make any landfall in the U.S.
The storm formed nearly two weeks after Hurricane Dorian battered the Bahamas as a devastating Category 5 storm. The islands are only now just beginning to tackle a daunting cleanup. Preliminary reports estimated Dorian caused some $7 billion in damage, although the government of the Bahamas has not yet offered any figure.
While the official death toll is at 50, the number is “expected to significantly increase” as around 1,300 people are still reported missing.
Kwasi Thompson, minister of state for Grand Bahama, warned Humberto will affect the entire island and urged people to seek shelter. "As previous storms have taught us, things change very quickly," he said. "We want residents to take it seriously."
