The Outer Banks in North Carolina are under evacuation warning as Hurricane Erin whips up potentially 20-foot high waves and flooding along the east coast.

A tropical storm watch has been issued and mandatory evacuations are underway along the coast of North Carolina, as Hurricane Erin approaches. Coastal flooding and massive waves could leave roads impassable for days.

Tropical storm conditions and coastal flooding are expected to appear in areas along the Outer Banks starting late Wednesday.
