EF1 Tornado — Tangipahoa, Louisiana

2025-10-26 · near Hammond Muni Arpt, Tangipahoa, Louisiana

Event narrative

An EF-1 tornado was confirmed by NWS ground survey northeast of Hammond, LA in Tangipahoa Parish. The ground survey first noted damage near River Rd and Arbuthnott Drive. The tornado moved generally northward to the east of River Rd causing additional damage mostly to trees. The strongest damage surveyed was along Dummyline Rd where it snapped several large trees, before the tornado crossed the Tangipahoa River. It then caused additional tree damage and destroyed a tent on the grounds of Camp Living Waters. Remote survey techniques utilizing high-resolution satellite imagery identified additional damage just north of Dusty Ln between Diana Ln and Calmes Ln, as a start point. The same imagery also indicated the tornado continued past the cap ground, causing tree damage near Robert Perkins Rd, and gradually weakening and lifting as it approached Chappepeela Rd.

Wider weather episode

A more pronounced mid-level impulse moving through a very moist and weakly forced environment supported the development of several mini tropical-like supercells across southeast Louisiana and coastal Mississippi during the early morning hours of October 26th. These storms produced several tornadoes, including EF-0 and EF-1 tornadoes across Livingston, Terrebonne, Tangipahoa Parishes as well as Jackson County. Multiple tornado tracks occurred over marsh and other inaccessible areas where damage consisted primarily of vegetation scarring and displaced trees, and were verified using high-resolution satellite imagery in conjunction with coherent tornado debris signatures observed on radar. Stronger tornadoes caused snapped and uprooted trees, minor to moderate roof damage, and localized structural impacts, including damage to a residence, a manufactured home, and several commercial and multi-family buildings in Gautier, Mississippi. The storms generally moved northeastward and exhibited brief cycles of intensification and weakening before lifting as they approached larger bodies of water or less favorable environments.
