The data shown on this page are based on 30 years of analysis (from 1980 to 2009) of tropical storms that affected North Carolina, either by direct landfall or a "close call". A storm's impact, including its radius, was determined by examining satellite data and comparing it against observed precipitation data from COOP, ASOS, ECONet and RAWS weather stations.
