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.

Hurricane Erin continued to track away from the United States on Friday, and attention is turning to two other potential storms in the Atlantic Ocean. The National Hurricane Center thinks both of the systems could become tropical depressions soon. And one seems to be on a path that those in the Caribbean will need to watch.

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