The damage path of an EF-1 tornado was identified over inaccessible rural marsh areas of southern Tangipahoa Parish. This radar confirmed tornado had a peak rotational velocity of near 40 knots and a tornado debris signature visible up to approximately 5300 feet. The tornado tracked over mostly marsh within the Joyce Wildlife Management Area. Highest resolution satellite data available from January 2017 showed evidence of broken branches and numerous uprooted trees along the Sinking Bayou. The tornado tracked northeast and grew in size and strength of the marsh peaking at around 200 yards in width which coincided well with the KLIX radar data. Additional displaced trees were identified along a separate canal around this time. The tornado then quickly weakened and occluded by 17:00 UTC as corroborated by the waning radar signature.
