Hurricane Jeanne was still swirling in the Atlantic Tuesday, but forecasters said they expected its 90 mph winds to weaken into a tropical storm as it heads toward Europe.

The hurricane was centered Tuesday morning about 480 miles west-southwest of Terceira in the Azores islands and was moving east-northeast at about 21 mph."It's moving over cooler waters and it will begin to move into the westerly windflow, which will kind of shear it apart," said meteorologist Daniel Brown.

Even in a weakened condition, Jean could threaten portions of Europe during the weekend, causing strong winds and heavy rain, Brown said.

This past week, for the first time since 1893, the Atlantic-Gulf region played host to four hurricanes at once - Georges, Jeanne, Ivan and Karl.
