■ Tropical storm may complicate hurricane relief efforts.

Relief agencies on Friday scrambled to deliver food and shelter materials to hurricane-ravaged communities in the Bahamas in advance of another storm that could drop as much as 6 inches of rain on the islands this weekend.

The agencies said their staffers will take cover if another storm passes through and will reemerge quickly to continue their deliveries.

“We are watching it closely,” said Grace Meinhofer, spokeswoman for the South Florida region of the American Red Cross. “None of the relief efforts will stop for this storm.”

The National Hurricane Center issued a tropical storm warning for most of the northwestern Bahamas, including Great Abaco Island and Grand Bahama Island, which were devastated by Hurricane Dorian earlier this month. Two to 4 inches of rain are expected over the weekend, although the center said some areas could see as much as 6 inches.

Maj. Clarence Ingram of the Salvation Army said his staffers and volunteers will suspend their efforts if a severe storm passes through and will then restart when it’s safe.

“We’ll keep going as long as we can,” Ingram said. “If we get a lot of wind and rain, people are in a very vulnerable position if all they have is the tarps on their roofs.”

Reuters reported that aid groups were rushing shelter material to residents living in the shells of former homes before the tropical storm hit the islands.

“We’re seeing plastic tarps go out all over the islands, and that’s extremely important because now you’ve got another tropical storm coming,” said Ken Isaacs, vice president of programs for the U.S. relief organization Samaritan’s Purse.

The storm will delay a humanitarian mission from the Port of Palm Beach by one day, according to the Bahamas Paradise Cruise Line. It had been scheduled to leave Friday night and come back on Monday, transporting Bahamians seeking safe haven in the U.S.

Those organizing the mission pressed Friday to work out logistics and were originally told by the U.S. Coast Guard that it would be safe to set sail Friday night and that the weather system would not affect the trip. But organizers ultimately decided to postpone the mission.

The ship will depart from the Port of Palm Beach on Saturday night, “weather permitting.”
