A National Weather Service Damage Assessment Team has surveyed the storm damage in Alton, LA. It has been determined the damage was the result of a tornado. The tornado has been rated an EF-1 on the Enhanced Fujita Scale. Damage estimates were consistent with winds of 90 mph.

A combination of high resolution satellite imagery, ground survey, and radar imagery has aided in the confirmation of a tornado that tracked across Alton and northwest parts of Slidell on the morning of April 10, 2024. This tornado touched down just south of Interstate 12 near Ben Thomas Road and tracked northeast. The tornado crossed Interstate 12 just west of US Highway 11 where the tornado was observed via video confirmation and ground survey of snapped trees. Sporadic tree damage continued northeast with more widespread tree damage being identified around Alton Elementary School. The tornado then crossed US Highway 11 where more tree damage was identified along Highway 1091. Damage became more sporadic and the end point of this tornado is harder to discern due to the beginning of a stronger and larger tornado that crossed nearby this area thereafter.
