National Weather Service meteorologists surveyed the damage in extreme southwestern Marengo County near Nanafalia and determined it was the result of an EF-2 tornado.

The tornado crossed the Tombigbee River from Choctaw County and widened and intensified. It produced significant damage on South Riverview Lane, just south of Alabama Highway 10. In this area, an older single wide mobile home was destroyed with the frame tossed at least 50 yards to the east. The river camp owner called the three residents of the mobile home and told the residents to shelter in a sturdier building which they did. In addition, a large storage building was also destroyed. Significant tree damage was noted in the area with several hardwood and softwoods snapped and uprooted. In this area, the tornado is estimated to have been at low end EF-2 intensity with winds around 115 mph. The tornado continued northeast and crossed Highway 10, producing substantial tree damage and also heavily damaging one barn and destroying another. The tornado continued to produce substantial tree damage as it crossed Highway 69. As the tornado moved east of Highway 69, the road network did not allow the survey team to assess the damage over a large forested area. However, damage was noted along Highway 17, north of Beaver Creek Road. It is not known how much further to the northeast the tornado continued due to no road access, but the tornado did not reach Highway 43.

Special thanks to NWS Mobile for completing this survey.
