Radar Estimated Rainfall Graphics
2012 Radar Estimated Rainfall. Most areas received over 40 inches of rain. Low values along the SC coast are bad data caused by radar beam blockage.
2012 Rainfall Departure, Carolinas. Most areas were slightly below normal for rainfall, although small portions of the Pee Dee Region actually had 4 to 8 inch rainfall surpluses. Low values along the SC coast are bad data caused by radar beam blockage.
2012 Rainfall Percent of Normal. Most areas were slightly below normal for rainfall, although small portions of the Pee Dee Region actually had 10-20 percent rainfall surpluses. Low values along the SC coast are bad data caused by radar beam blockage.
