GONAIVES, Haiti, Sept 4 (Reuters) - Powerful Hurricane Ike weakened slightly as it charged across the Atlantic toward the Bahamas and the United States on Thursday while Tropical Storm Hanna's death toll from floods in Haiti grew to 90.

Campgrounds were closed and some evacuations began on North Carolina's Outer Banks as Hanna churned east of the far-flung Bahamian chain of 700 islands on a path toward the southeastern U.S. states on Saturday.

Ike posed no immediate threat to land and it was too early to say if it would threaten Caribbean islands, the U.S. East Coast or the U.S. oil fields in the Gulf of Mexico. Tropical Storm Josephine churned in Ike's wake across the Atlantic.

The trio of Atlantic storms followed Hurricane Gustav's rampage through the Caribbean to the Louisiana coast, where it slammed ashore on Monday west of New Orleans, largely sparing the city devastated by Hurricane Katrina three years ago.

The flurry was a clear signal that this six-month hurricane season was on track to be a ferociously busy one, though not like record-busting 2005 when 28 tropical storms, including Katrina, rolled across the Atlantic and Caribbean.
