EF0 tornado in Iberville Parish, Louisiana

An EF-0 tornado was confirmed to have tracked south of Interstate 10 over primarily rural lands of the Atchafalaya Basin. High resolution satellite imagery depicted a scalloped swath of tree damage associated with a strong circulation within a line of thunderstorms. Some uprooted trees and large branches were identified via ground survey where this tornado crossed Atchafalaya Basin Levee Rd, the only road that could be accessed to assess its intensity.

A stationary front was setup along the gulf coast on May 13th. High instability and progressive flow aloft ignited a storm complex over southeastern Texas during the mid afternoon hours. Those storms quickly formed into a linear complex that rode along the stationary boundary, favoring the thermal and instability gradient. The complex made its way across southern Louisiana, producing destructive straight-line winds with embedded tornadoes. The complex dove south into the Gulf of Mexico off of the Mississippi coast, favoring the instability where it continued to produces significant wind gusts before exiting the coastal waters.
