Nassau, Bahamas ? Tropical Storm Hanna roared past the edge of the Bahamas on Thursday ahead of a possible hurricane hit on the Carolinas, leaving behind at least 137 dead in Haiti.

Hurricane Ike, a still-more-dangerous Category 4 storm, was advancing from the east.

Hanna blew by the Bahamas late Thursday, knocking out power to Cat Island and causing minor flooding in other eastern islands, but sparing the Atlantic nation major damage.

U.S. National Hurricane Center said Hanna should reach the coast of North or South Carolina by Saturday, but its sprawling bands of outer winds are likely to hit the U.S. sooner.

Haiti’s government more than doubled Hanna’s death toll late Thursday to 137. Hanna’s heart was about 540 miles south of Wilmington, North Carolina, late Thursday night.

It was moving toward the northwest near 14 mph. Its maximum sustained winds were 65 mph. Forecasters said it could become a hurricane before hitting the U.S.

By Thursday night, Ike had maximum sustained winds near 135 mph. It was centered 475 miles north-northeast of the Leeward Islands, and forecasters said it could reach the Bahamas by late Sunday or Monday.

Josephine followed behind, with maximum sustained winds near 45 mph.
