2. EF186 to 110 mph

   Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

3. EF2111 to 135 mphthis tornado

   Considerable damage. Roofs torn off well-built houses, frame homes shifted on their foundations, mobile homes destroyed, large trees snapped or uprooted, cars lifted off the ground.

4. EF3136 to 165 mph

   Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.

5. EF4166 to 200 mph

   Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

6. EF5over 200 mph

   Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.

7. Unrated

   The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

9 damage points were recorded along this path by NWS FFC, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF2. The highest wind the damage implies is 130 mph.

A stationary front was draped across north Georgia early on May 10th with an active northwest flow aloft. Meanwhile...a vigorous short wave aloft was approaching the area from the southern plains. The stationary front provided the focus for two rounds of showers and thunderstorms, one early in the morning on the 10th and another in the afternoon. The activity tracked east-southeast with the upper flow aloft, mainly across north Georgia during the early morning and across central Georgia during the afternoon. An isolated strong supercell also tracked across the southern part of central Georgia during the evening. After a lull of convective activity for about four hours, intense multicell thunderstorms tracked into the area from Alabama after midnight and before dawn on the 11th. As these thunderstorms tracked across west central and central Georgia, 15 tornadoes were identified by subsequent surveys making this the most significant tornado outbreak to affect the area since the Katrina-associated tornadoes on August 29, 2005. Millions of dollars of property damage were reported as many homes were destroyed from these tornadoes from the western and southern suburbs of Atlanta southeastward across Macon, Dublin, and other counties in east central and southeast Georgia. Many of these counties were eligible for disaster assistance from the federal government.||In addition to the tornadoes and thunderstorm winds that caused extensive damage in dozens of counties across north and central Georgia during the early morning hours of May 11th, strong gradient winds developed on the back side of the strong cold front that moved through the area as low pressure intensified across the mid-Atlantic region. The strong winds combined with wet ground resulted in dozens of trees being blown down in some north Georgia counties. There were also two deaths as a result of downed trees in Barrow and Gwinnett county, all non-thunderstorm-related winds.

A damage survey conducted by the National Weather Service Forecast Office in Peachtree City, Georgia confirmed that an EF2 tornado touched down near Lizella and continued across Bibb county into extreme western Twiggs county near Dry Branch producing sporadic, but significant damage as it varied in intensity from EF0 to EF2. The tornado tracked from just east-northeast of Lizella across the south shores of Lake Tobesofkee, then across the city of Macon, producing widespread significant damage, and then eastward to the Twiggs county line. By far the most significant damage occurred within the city of Macon, especially along Eisenhower Parkway and Pio Nono Avenue where two businesses were completely destroyed and several others were heavily damaged. Macon State College was also hit by the tornado, destroying the gymnasium and causing significant damage to a number of other buildings on the campus. In addition, more than 50 percent of the trees on the campus either snapped in half or uprooted. Maximum wind speeds within the tornado were estimated at 130 mph, which occurred near the intersection of Eisenhower Parkway and Pio Nono Avenue. Nearly all of the 18 mile long path of the tornado fell within Bibb county. Less than one mile of the tornado occurred within Twiggs county. The maximum path width of the tornado was estimated to be 100 yards, mainly as it traveled through the Macon State College area.||A summary of damages from Bibb county shows that 1,479 homes suffered at least some damage as a result of the storms. Ninety-three of these homes were destroyed, 275 suffered major damage, and 569 sustained minor damage.

A damage survey conducted by the National Weather Service Forecast Office in Peachtree City, Georgia confirmed that the same thunderstorm that earlier spawned the destructive EF2 tornado that tracked across Bibb county into western Twiggs county, shortly thereafter spawned yet another EF0 to EF1 tornado across central and east central Twiggs county. The tornado, which initially touched down as an EF0 tornado just east-southeast of Fitzpatrick, briefly strengthened to an EF1 tornado as it moved east, then sporadically fluctuated between EF1 and EF0 intensity as it continued on an almost due eastward track into Wilkinson county, crossing into Wilkinson county about 4 1/3 miles southeast of Myricks Mill. The tornado touched down near the intersection of U.S. Highway 80 and Myricks Mill Road where the roof of a church was destroyed. Four other churches sustained minor damage, along with 30 homes, mostly from downed trees. Five vehicles were damaged or destroyed. Tons of trees were either uprooted or twisted throughout the area, leaving several roads blocked and closed, including parts of Interstate 16. A number of power lines were also knocked down. Maximum sustained winds of the tornado within Twiggs county were estimated to be 90 mph, with a maximum path width of 100 yards. While the overall path length of this tornado was 25 miles, just a little over five miles of the path occurred within Twiggs county.

13 minutes of warning. NWS FFC issued a tornado warning for this county at 09:37 UTC, 13 minutes before the tornado touched down, in force until 10:15 UTC.

The county was under a tornado watch, issued at 06:45 UTC and running to 14:00 UTC.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Slight Risk, with a 0.05 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 06:03 UTC.

41 more were confirmed in the United States that day.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
