EF1 tornado in Chattahoochee County, Georgia

A damage survey conducted by the National Weather Service Forecast Office in Peachtree City, Georgia, confirmed that an EF1 tornado had touched down approximately 2.5 miles south of Ochille and continued on an east-southeastward track across central Chattahoochee county, lifting about 4.0 miles east-southeast of its touchdown point. The path width was determined to be 440 yards with maximum winds estimated at 80 mph. The damage appeared to have begun as a downburst, within which the brief EF1 tornado spin up occurred. Combined damage from the downburst and EF1 tornado consisted of destruction of several out buildings and sheds. Hundreds of trees were flattened along the path of the tornado. Another EF1 tornado was spawned from the same supercell thunderstorm, also within Chattahoochee county, just eight minutes later and four miles further east.

A vigorous upper closed low was moving from the mid-south and Mississippi valley region into the mid-Atlantic and southeast U.S. A strong cold front accompanied the upper system. A strong low-level jet in advance of these weather systems transported warm, moist Gulf air northward into the region. With strong dynamics, hence shear, combined with an unusually moist, unstable atmosphere, the atmosphere was primed for a major weather outbreak. One round of thunderstorms passed through north Georgia during the early morning hours. A few minor severe weather events accompanied this system in northwest Georgia. Partial clearing followed the morning convection, allowing temperatures to soar into the mid 70s across much of north and central Georgia in advance of the main weather system. Scattered to numerous discrete supercell thunderstorms developed during mid-afternoon in northwest Georgia and progressed east and southeast across the remaining portions of the county warning area during the evening hours. Severe thunderstorms and tornadoes lingered into the early morning hours of the 11th across the southern counties of central Georgia. During the eight hour period from 5 pm EDT on April 10th to 1 am EDT on April 11th, a total of 14 tornadoes were confirmed to have touched down in north and central Georgia causing millions in damages. While some injuries were observed, no deaths were observed.
