EF0 Tornado — Harrison, Mississippi

2024-04-10 · near Ligana, Harrison, Mississippi

Event narrative

As the mesovortex tracked east into Harrison County, another tornado developed on the trailing flank of it and tracked east-southeast over primarily inaccessible rural land near the Wolf River. High resolution satellite imagery NDVI differencing identified a scalloped path that starts near F Malley Road in Dedeaux, MS and continues east-southeast where a ground survey identified numerous large tree branches snapped as well as a mobile home that had slid off its blocks. The tornado crossed River Road with minimal damage evident although the track remained visible on NDVI differencing as it crossed the Wolf River. The most notable tree damage from this tornado appears to be located along the river bank, but is not accessible to provide a rating for. The apparent track of the tornado continues east across Wolf River Road and appears to conclude just short of Alcede Lizana Road.
