F2 tornado, Jake to Bremen, Georgia, May 7, 1999

From Jake to Bremen, this F2 tornado ran 10.0 miles across Carroll and Haralson counties on May 7, 1999, touching down at 4:22 PM EDT and reaching 150 yards wide. It killed nobody and injured 3, and did $600,000 of property damage.

The rating scale

Tracks are drawn in the color of the rating. The Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.

  1. F040 to 72 mph

    Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

  2. F173 to 112 mph

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

  3. F2113 to 157 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. F3158 to 206 mph

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

  5. F4207 to 260 mph

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

  6. F5261 to 318 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.

What the Weather Service recorded

Sight survey by NWS personnel and newspaper accounts determined that the tornado touched down in Carroll county near Five Points Road and Mt Zion Road. The storm path was to the northeast across Interstate 20 and then into Haralson county. All along the path there was structural damage to several homes, businesses, barns and outbuildings. Many hundreds of trees were snapped or uprooted, which caused much of the damage. Several of the trees were very large hardwoods and pines. There was also extensive damage to power and telephone lines.

The tornado continued northeast from Carroll county and crossed into Haralson county southwest of Bremen. There was heavy damage to a mobile home dealership in Bremen, where around 35 mobile homes were damaged or destroyed. Debris was tossed across the highway. The tornado continued northeast and did damage at the Maple Creek golf course before lifting. Newspaper accouints said three people in Haralson county were taken to the hospital with fractures.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

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 forecast that day

The Storm Prediction Center had this point in a Slight Risk. The outlook in force was issued at 19:55 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

What this means

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.
