EF0 tornado in Livingston Parish, Louisiana

An EF-0 tornado crossed Bear Island Road south of Hwy 22, causing damage mostly to trees. One home suffered minor roof damage, and a large metal canopy was thrown about 25 to 40 yard to the southeast. High resolution satellite imagery helped to identify the start and end of this tornado over the inaccessible marsh areas where defoliation and minor tree damage were evident. The marsh damage was also collocated with an evident tornado debris signature on KHDC radar imagery.

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.
