A National Weather Service Damage Assessment Team has surveyed the storm damage in Pierre Part, LA. It has been determined the damage was the result of tornado that formed along the leading edge of a squall line. The tornado has been rated an EF-1 on the Enhanced Fujita Scale. Damage estimates were consistent with winds between 80 & 100 mph.

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. A metal warehouse building had doors blown inward at this location. The tornado then moved into the woods near the end of Noe Street where large branches were snapped off. The tornado remained 150 yards wide at this point. No access was available beyond this point, and it is unknown if the tornado remained on the ground beyond the end of Noe Street.
