3 damage points were recorded along this path by NWS FFC, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 85 mph.

• Report from EM... several large trees down across Coleman Creek Circle (exact location in question)
• EM report of several smaller trees down across Charlie Fuller Road, just north of Primrose Rd

The remains of Tropical Storm Fred moved across central and north Georgia as a tropical depression during the overnight hours through the morning producing isolated reports of damaging winds in convective bands and several tornadoes. No reports of wind damage were received outside of the stronger convective bands. Rainfall amounts exceeded 4 inches in portions of northeast Georgia, with amounts of 6 to 8 inches observed in the northeast Georgia mountains.

A National Weather Service survey found that an EF0 tornado with maximum wind speeds of 85 mph and a maximum path width of 150 yards touched down near Coleman Creek Circle just east of Highway 27/41 (Roosevelt Highway) in northwest Meriwether County, snapping several large trees along Coleman Creek Circle. The tornado moved west northwest, crossing Roosevelt Highway downing additional trees across Sawmill Road to Charlie Fuller Road before dissipating just west of Charlie Fuller Road. [8/17/21: Tornado #2, County #1/1, EF-0, Meriwether, 2021:016].

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

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down. One was issued for the county at another hour that day.

The county was under a tornado watch, issued at 07:48 UTC and running to 12:39 UTC.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. 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 General Thunderstorms Risk. The outlook in force was issued at 05:40 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.

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.
