The United States National Weather Service has released a preliminary report mapping out the tracks of the deadly tornadoes which battered North Carolina on April 16, 2011.
The Enhanced Fujita Scale (EF Scale) rates the strength of tornadoes. Higher numbers signify storms capable of causing more damage. The EF-2 and EF-3 events shown here had wind speeds of up to 135 mph (217 km/h) and 165 mph (217 km/h) respectively, resulting in considerable and severe damage.
