Event narrative

An EF-1 tornado touched down on the northwest side of the Hammond Northshore Regional Airport just before 4am CDT where patches of large branches were snapped. The tornado continued to the north-northwest across highways 443 and 1064 where it maintained EF-0 strength by snapping small branches. The tornado remained over rural parts of northern Hammond while steadily picking up strength. The tornado was nearing peak intensity as it approached the intersection of Faller Rd and Tycer Ln at 4:06am where a house lost an awning and parts of its roof. The tornado finally reach peak intensity at as it continued to the north-northwest and approaches the intersection of Faller Rd and McManus Dr. Here, a hardwood tree was snapped in the middle. The tornado maintained this peak intensity as it approached Highway 442 where a few more hardwood trees were snapped. The tornado began weakening after this point as is continued to make its way to the north-northwest and across the Tangipahoa River. As it crossed the river, it practically paralleled S Bennett Rd in Independence, LA where it mainly snapped large branches until it lifted shortly before Highway 40 at 4:14am.

Wider weather episode

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.
