According to a 5 a.m. ET advisory from the National Hurricane Center on Aug. 20, Erin is located about 455 miles south-southeast of Cape Hatteras, North Carolina, with maximum sustained winds near 100 mph with higher gusts.

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.
