Hurricane Jeanne May Head to U.S.

Deadly Hurricane Jeanne (search) could head back toward the United States and threaten the storm-battered Southeast coast, including Florida, as early as this weekend, forecasters said Wednesday.

It was too soon to tell where or if Jeanne would hit, but forecasters at the National Hurricane Center (search) in Miami warned residents from Florida to Maryland to watch the storm with 90 mph top sustained winds.

Some computer models had Jeanne curving out to sea and missing land, but others had it hitting the United States on Saturday or Sunday, forecasters said.

Jeanne was blamed for more than 700 deaths in Haiti, where it hit over the weekend as a tropical storm and caused flooding. It had been moving out to sea, but appeared to be looping back toward land, forecasters said.

At 5 p.m. EDT, Jeanne was centered about 500 miles east of Great Abaco Island in the Bahamas. The storm was moving west-southwest at about 5 mph and was expected to turn to the west by Thursday.

Dangerous surf and rip currents along with large swells are possible along the southeastern U.S. coast over the next few days, forecasters said. If Jeanne hit Florida, it would follow Hurricanes Charley, Frances and Ivan, which caused billions of dollars of damage and more than 60 deaths across the state.

A remnant of Ivan in the Gulf of Mexico threatened to turn into a tropical storm Wednesday on a path toward southwestern Louisiana and Texas. The disturbance kicked seas up several feet, posing a threat to fragile barrier islands on the Louisiana coast. Computer models pointed to landfall Friday or on the weekend, but not as a very strong storm.

Hurricane Karl (search) weakened slightly Wednesday and stayed on an open-ocean course that only threatened ships, while Tropical Storm Lisa (search) moved slowly far out in the Atlantic.

Karl, the seventh hurricane this season, had top sustained winds of about 105 mph, down from about 120 mph a day earlier. At 5 p.m., Karl was centered about 1,400 miles west-southwest of the Azores and was moving north at about 16 mph.

At 5 p.m., Lisa had top sustained winds near 50 mph, down from about 70 mph a day earlier. The 12th named storm of the season was centered about 1,205 miles west of the Cape Verde Islands and was moving west-northwest at about 6 mph.

The hurricane season ends Nov. 30.
