MIAMI (Reuters) - Hurricane Arthur was upgraded to a Category 2 storm with maximum sustained winds at 100 miles per hour (160 kilometers per hour), the U.S. National Hurricane Center said on Thursday evening. Arthur was fast approaching the coastline of North Carolina and expected to make landfall late Thursday or early Friday morning, forecasters said as weather conditions deteriorated in the Outer Banks, where vacationers were forced to evacuate on the eve of the July 4 holiday.
