1 death – This intense tornado, moving northeastward, destroyed a home, five barns, one hay shed, two garages, and 10 t (22,000 lb; 10,000 kg) of hay. One home was unroofed as well. There were eight injuries, one of which was serious, and $2,500 in damage. The CDNS report listed only four injuries. Grazulis classified the tornado as an F2.[10][11]
Strong tornado accompanied by strong winds and hail formed west of Anderson and touched down three times as it moved southeastward through Carney and Dudley throwing debris high into the air. There was $2,500 in damages. Advance warning allowed most residents to take shelter in storm cellars before the storm, which reportedly had a high-pitched roar. Grazulis did not list the tornado as an F2 or stronger.[12][13]
Tornado moved eastward directly through Yarbro. Two homes were heavily damaged, one of which was destroyed, and there was considerable damage to farm buildings, power and telephone lines, and sign boards. The tornado destroyed a barn as well. Losses totaled $2,500. Some small, non-damaging hail also fell with this storm. Grazulis classified the tornado as an F2.[14][15]
This intense tornado first hit in the Wragg Swamp west of Mobile and moved north-northeastward past the University of South Alabama campus before turning more northeastward. It passed within 1⁄2 mi (0.80 km) of the Spring Hill seismograph, causing an abrupt vibration which lasted for one minute and 13 seconds. A building materials warehouse and 11 homes were destroyed and other buildings damaged. The tornado also tossed a home against another 200 yd (180 m) away. There were 15 injuries and $25,000 in damages. Grazulis classified the tornado as an F2.[18][19]
This event was listed as a probable tornado by the CDNS report because the fallen trees indicated straight-line winds, but the narrow path suggested that the damage area was possibly in the right hand side of a large, weak tornado that moved north-northeastward instead. One house was unroofed and three other buildings were damaged. Losses totaled $2,500.[20][21]

^The Fujita scale was devised under the aegis of scientist T. Theodore Fujita in the early 1970s. Prior to the advent of the scale in 1971, tornadoes in the United States were officially unrated.[1][2] While the Fujita scale has been superseded by the Enhanced Fujita scale in the U.S. since February 1, 2007,[3]Canada utilized the old scale until April 1, 2013;[4] nations elsewhere, like the United Kingdom, apply other classifications such as the TORRO scale.[5]
^Historically, the number of tornadoes globally and in the United States was and is likely underrepresented: research by Grazulis on annual tornado activity suggests that, as of 2001, only 53% of yearly U.S. tornadoes were officially recorded. Documentation of tornadoes outside the United States was historically less exhaustive, owing to the lack of monitors in many nations and, in some cases, to internal political controls on public information.[6] Most countries only recorded tornadoes that produced severe damage or loss of life.[7] Significant low biases in U.S. tornado counts likely occurred through the early 1990s, when advanced NEXRAD was first installed and the National Weather Service began comprehensively verifying tornado occurrences.[8]
