H urricane Erin, now a Category 2 hurricane, has prompted a tropical storm watch for North Carolina's Outer Banks and is expected to bring dangerous waves and rip currents to beaches along the East Coast. While the storm won't make landfall on the East Coast, it has prompted mandatory evacuations for some Outer Banks residents and visitors.

North Carolina Gov. Josh Stein declared a state of emergency on Tuesday as Hurricane Erin makes its way along the U.S. East Coast, his office said.
