“Erin is a large hurricane,” forecasters said, noting that hurricane-force winds extend up to 80 miles from the storm’s center, with tropical-storm-force winds reaching up to 205 miles.

As Erin’s wind field continues to expand, the storm is fueling widespread, destructive surf conditions and dangerous rip currents along the coast from Florida to New York. The risk for the East Coast will last until the end of the week, prompting many beaches to ban swimming.

The massive storm is expected to bring coastal flooding and tropical storm conditions to parts of the mid-Atlantic despite not making landfall.

Two people are dead and another person is missing after Hurricane Erin passed by the United States last week. Although the storm never made landfall, it did make an impact on the East Coast, causing dangerous currents.

A tropical storm warning remains in effect for Bermuda. The storm will move northeast as it heads out to sea and away from land.

Erin, the first hurricane to develop over the Atlantic this year, became post-tropical on Friday afternoon, the National Hurricane Center said.

Authorities predicted flooding, surges and swells along some parts of the East Coast even as Erin moves out toward the ocean.

The storm has already prompted an evacuation order for Hatteras Island on North Carolina's Outer Banks and warnings about dangerous rip currents and swells along the East Coast.

Hurricane Erin could 'at least double or triple in size' next week and the track has shifted south, but remains likely to turn away from the East Coast.
