Summary

An EF-1 tornado with maximum wind speeds of 100 to 110 mph touched down in the in the Haws Run area of Onslow County approximately 10 miles southwest of Jacksonville around 9:30 AM. The damage path began along Haws Run Road, about 4 miles north of NC Highway 50, and mostly paralleled the road as it produced damage moving northeast. The tornado maintained mostly consistent strength throughout its path, though there were sections where the tornado briefly lifted and damage was more sporadic and less severe. In the most concentrated areas of damage there were numerous mature softwood and hardwood trees snapped at the trunk,uprooted, and twisted/splintered. This included several large limbs or trees that had fallen on top of manufactured homes. Perhaps the most pronounced damage occurred at a hog farm where the hog houses were completely destroyed, with many sections of the metal roof and insulation thrown up to several miles away from the farm. From there the tornado moved through a small residential neighborhood producing continued widespread tree damage, reaching its end point shortly thereafter just past the intersection of NC Highway 53 and Murrill Hill Road.

For reference:

EF Scale: The Enhanced Fujita Scale classifies tornadoes into the following categories:

EF0 Weak 65 to 85 mph
EF1 Weak 86 to 110 mph
EF2 Strong 111 to 135 mph
EF3 Strong 136 to 165 mph
EF4 Violent 166 to 200 mph
EF5 Violent >200 mph

 

A microburst is a convective downdraft with an affected outflow area of less than 2 1/2 miles wide and peak winds lasting less than 5 minutes. Microbursts may induce dangerous horizontal/vertical wind shears, which can adversely affect aircraft performance and cause property damage. Straight-line winds are generally any wind that is not associated with rotation, used mainly to differentiate them from tornadic winds.
