A powerful storm system moved across the mid-south and southeast United States producing widespread severe weather and numerous tornadoes. In middle Georgia, significant damage from fourteen separate tornadoes was observed. Thousands of trees were snapped or uprooted and numerous homes and businesses were damaged or destroyed. Across central Georgia, incredibly, no deaths were reported, with only around a dozen minor injuries.

A National Weather Service survey found that an EF1 tornado with maximum wind speeds of 100 mph and a maximum path width of 900 yards occurred in Harris County. The tornado touched down just west of the intersection of Hopewell Church Road and Hamilton Pleasant Grove Road. The tornado traveled east northeast along Hopewell Church Road and then Highway 18 where it intensified, downing hundreds of trees, several falling on homes. As the tornado approached the city of Pine Mountain it reached its maximum intensity of 100 mph and moved across the south side of the city. A large tree fell onto an apartment on S. King Avenue destroying one of the rooms on the second floor. The tornado weakened as it continued east before lifting just west of the intersection of Davis Lake Road and Cold Springs Road. No injuries were reported. [03/03/19: Tornado #9, County #1/1, EF1, Harris, 2019:014].

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 17:28 UTC and running to 21:38 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 Enhanced Risk, with a 0.10 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 20:00 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.

44 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.
