This morning Hurricane Bill became a dangerous Category 4 storm with maximum sustained winds near 135mph, and forecasters now say that it could get even stronger as it moves over the open Atlantic. As of early Wednesday, Bill was located about 460 miles east of the Leeward Islands and was moving west-northwest near 16mph.

The National Hurricane Center has advised residents of the Leeward Islands to monitor the storm's progress, even though the core of the storm is expected to pass well to the northeast of the islands sometime either late Wednesday or early Thursday.

Bill's biggest threat could be to Bermuda, which the storm may pass in three or four days. However, it could also slide directly between Bermuda and the eastern coast of the U.S. without making landfall.

Over the next few days, those along the coast can at least expect wave swells and rip currents.
