Event narrative

Public picture of a waterspout on Lake Pontchartrain.

Wider weather episode

Persistent low-level moisture and weak convergence along a stalled frontal boundary once again supported the development of scattered showers and thunderstorms over the coastal waters. Within this environment, a couple of waterspouts were reported. One occurred over Lake Pontchartrain and another observed south of Grand Isle. Both waterspouts remained over water and dissipated within several minutes. No damage or injuries were reported.
