The tornado touched down along a gravel driveway near Derrick Street north of Pierre Part snapping off large branches along the driveway and producing EF-0 damage. The path width was approximately 50 yards wide at this point. The tornado then moved East-Southeast and crossed Derrick Street damaging several homes and snapping hardwood trees. A carport was destroyed at one residence and a porch collapsed at another home. A third home had most of the tin roofing torn off the back of the house. The tornado strength was rated an EF-1 with a path width of 150 yards in this area. The tornado continued moving East-Southeast and crossed Louisiana Highway 70 and then paralleled Lee Drive causing sporadic tree damage along the road and causing minor damage to homes. The tornado was rated an EF-0 and the path width was 150 yards at this point. The tornado then intensified as it reached the intersection of Lee Drive and East Drive regaining EF-1 status. A home had the chimney collapse and another home had a large portion of the tin roof removed with the wooden beams exposed. Several large trees were also snapped at the base in this location. The path width was still 150 yards wide as it crossed Avoca Island Cutoff Canal, but the tornado weakened back to EF-0 strength as it crossed Grand Coupe Lane.
