EF0 tornado in Caddo Parish, Louisiana

An EF0 tornado with estimated maximum winds near 85 mph developed during the afternoon on March 28th, 2025, associated with a small supercell moving across northern Caddo Parish just to the south of the towns of Vivian and Hosston. The storm began to rotate and produced a tornado debris signature (TDS) on the dual polarization radar product, correlation coefficient (CC), just west of Centerville Road and south of Highway 2 near Black Bayou Lake. This indicated that debris was lofted from the circulation, although the damage survey team was unable to locate any visual damage near the initial TDS in this location. Therefore, EF-Unknown (EFU) rating was given in this area. The tornado then crossed Highway 2 and moved along an unnamed/unpaved roadway just to the south of Black Bayou Lake. The EFU rating was continued in this area given the persistent TDS signature on radar despite no visual evidence of damage. The tornado then passed over Black Bayou Lake before reaching Rudd Road and Ed Road on the north-central side of the lake. At this location, there was evidence of physical damage to trees in the form of large branches broken and several uproots, indicative of winds around 75-80 mph. The tornado moved due north along Rudd Road to the intersection of Wynn School Road where additional tree damage was found. The tornado reached Mira Myrtis Road where the most extensive damage was found. Along this road, especially between Wynn School Road and Hosston Rodessa Road South, there were several trees uprooted, large branches broken, and structural damage to a garage/shed next to a home where the roof of the shed was damaged. Based on the extent of the roof damage and the surrounding area, wind speeds were estimated at high-end EF0 around 85 mph. The tornado continued northward, with minimal damage found, but evidence of a continued weak TDS signature, prompting another EFU rating. The tornado then moved north of Tyson Road and near or along Atlanta Mira Road where additional tree damage was noted. Thereafter, the tornado appeared to have lifted, with no additional damage found and no indication of a continued TDS signature present. In addition, radar velocity data indicated weakening circulation as the storm continued toward the Louisiana/Arkansas border.

Numerous showers and thunderstorms developed across the Four State Region on March 28th in response to an upper-level disturbance moving across the Red River Valley of North Texas and Southern Oklahoma. As the afternoon hours progressed, strong southerly flow allowed for temperatures and dew points to rise, creating a more unstable atmosphere with MLCAPE values approaching 1000 J/kg. Thunderstorms started to strengthen in intensity during this period, with modest shear profiles across East Texas, Western Louisiana and adjacent Southwest Arkansas. Rotational signatures were detected in several of the stronger storms through the evening hours. This required the issuance of several tornado warnings across the aforementioned areas. As a result, an EF0 tornado was reported in Caddo Parish. There was also some locally heavy rainfall with this event, with flash flooding being reported in Sabine Parish.
