EF0 tornado in Livingston Parish, Louisiana

Minor vegetation damage was identified using high resolution satellite imagery to verify the track of a radar-confirmed EF-0 tornado that occurred near Blind River, southeast of Denson, LA in Livingston Parish. This weak tornado remained away from any structures though a weak, but conclusive tornado debris signature was visible on KHDC radar imagery which aligned with intermittent minor vegetation over the marsh. Most notably a few trees were visibly displaced on the bank of Blind River.

A small mid-level impulse moving through a moist and weakly forced environment supported the development of several mini tropical-like supercells across southeast Louisiana during the late evening of October 5th into the early morning hours of October 6th. These storms produced several tornadoes, including an EF-0 tornado over marshland near Blind River in Livingston Parish and multiple tornadoes across Tangipahoa Parish, where the strongest reached EF-1 intensity and caused tree damage and localized roof damage. Some tornado tracks were verified using high-resolution satellite imagery in areas with limited ground access, and weak but coherent tornado debris signatures were observed on radar. Later in the morning, convection moved across Lake Pontchartrain where a waterspout was observed and confirmed just east of the Causeway Bridge using photographic and drone footage.
