Miami (AP) - Bermuda is being pelted by rain, courtesy of Hurricane Bill -- which is threatening to flood the island's coastline.

The center of the storm is expected to pass between Bermuda and the U.S. east coast tomorrow.

The storm's top winds are clocked at about 115 miles an hour, and forecasters say its intensity could fluctuate in the next two days.

North Carolina is expecting flooding and beach erosion on the outer banks this weekend.

And emergency managers in New England are warning boaters, swimmers and surfers to take extra precautions this weekend, when waves off the coast are expected to swell to 35 feet.

The hurricane could affect some high-profile vacations. Bill and Hillary Clinton arrived in Bermuda on Wednesday for a 3- or 4-day getaway. And President Barack Obama and his family are due on Martha's Vineyard on Sunday.
