This caused the National Weather Service to upgrade the tornado to an EF-5. However, at the end of August the National Weather Service re-assessed their findings and put the tornado back to an EF-3 rating citing the Enhanced Fujita rating system uses damage to estimate the intensity and they only found damage equivalent to an EF-3.
