EF1 tornado in Tangipahoa Parish, Louisiana

An EF-1 touched down south of Robert, LA at 5:11am CDT along Traino Rd where a few small limbs were snapped. The tornado quickly gained strength as it moved north towards Highway 22. The tornado reached peak intensity as a 90mph EF-1 at 5:14am along Highway 20 just east of the Fairhope Subdivision where a group of softwood trees were snapped. This tornado maintained peak intensity as it continued northward towards Crown Dr at 5:18am. Here more softwood trees were snapped and a roof was partially removed from a manufactured home. The tornado began to weaken and occlude as it moved to the northeast. The tornado broke small limbs and caused small trees to lean in a convergent pattern before lifting at 5:21am just southwest of Jasper Ln south of Robert, LA.

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.
