Hurricane Erin has weakened to a Category 1 storm after lashing North Carolina's Outer Banks with rough waves and coastal flooding, and bringing a threat of dangerous waves and potentially deadly rip currents to the East Coast.

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

Increased surf and dangerous rip currents are expected to continue along the eastern seaboard as Hurricane Erin moves into the North Atlantic.
