What EF3 means. On the Enhanced Fujita scale, EF3 is severe damage: whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, consistent with estimated gusts of 136–165 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

Several powerful super-cell thunderstorms developed ahead of an approaching cold front. Conditions ahead of the front were favorable for tornadoes with a moderately unstable atmosphere combined with strong winds that veered with height. Altogether 12 tornadoes were reported across the Newport/Morehead City county warning area. These tornadoes combined to produce over 40 million dollars in damages. There were numerous injuries but no fatalities were reported. In addition to the tornadoes there were several reports of damaging winds and large hail.
