Five additional tornado damage paths have been confirmed across portions of Harrison and Jackson Counties in Mississippi and West Feliciana Parish in Louisiana. Four new tornadoes were identified while the track for two previously-confirmed tornadoes were revised and connected into one long-tracked tornado between Pointe Coupee and West Feliciana Parishes. Of particular note, high resolution satellite imagery showed the track of the Labarre- Spillman, LA tornado was much longer than the initial ground survey revealed. Consequently, the updated path length increased from 9 miles to 32 miles with the tornado touching down just south of Morganza, LA in Pointe Coupee Parish and dissipating shortly after it crosses into Wilkinson County, Mississippi. The most significant damage occurred between Bains, LA and Spillman, LA as identified via high resolution satellite imagery and initial ground survey. The tornadoes in Harrison County were identified using high-resolution satellite imagery which aligned with ground- surveyed damage points in the area. An apparently weak, but unrated tornado was also identified in Jackson County, MS which tracked over rural mostly inaccessible lands. Possible tornado damage was also identified in Innis, LA which will require further investigation. Further adjustments to peak intensity are possible especially with the long-tracked tornado where another damage survey team is planning to revisit the area on Monday. This will assist in finalizing the peak intensity and an increase to an EF-2 rating tornado in West Feliciana Parish is likely. .Labarre-Spillman, LA Tornado... Rating: EF1 Estimated Peak Wind: 110 mph Path Length /statute/: 32.39 miles Path Width /maximum/: 1760 yards Fatalities: 0 Injuries: 0 Start Date: 04/10/2024 Start Time: 07:58 AM CDT Start Location: 3 SSW Morganza / Pointe Coupee Parish / LA Start Lat/Lon: 30.6925 / -91.6102 End Date: 04/10/2024 End Time: 08:27 AM CDT End Location: 6 NNE Spillman / Wilkinson County / LA End Lat/Lon: 31.0152 / -91.2345 Survey Summary: A strong and long-lived tornado tracked across portions of Pointe Coupee and West Feliciana Parishes carving out a nearly 33-mile- long path with a maximum width of approximately 1 mile just southwest of Spillman, LA. Per NDVI differencing on satellite analysis, this tornado formed south of Morganza, LA within a powerful line of thunderstorms and quickly moved northeast over mainly rural lands before causing more substantial tree damage as it crossed Morganza Hwy. The tree damage became increasingly more widespread and intense as the tornado crossed Levee Road and the Mississippi River. High resolution satellite imagery identified a focused swath of tree damage roughly 400 yards in width that continued northeast through the Cat Island National Wildlife Refuge up through US Highway 61. Tree damage was observed on Highway 61 with another large swath of tree damage further northeast on Bains Road. Due to the heavily wooded and rural areas, ground surveys were impeded in identifying parts of this track as it continued northeast. The tornado quickly grew in size thereafter and the most significant damage began after the tornado crossed Polk Brannon Road. The ground survey was able to access along Spillman Road and Jones Vaughn Creek Road where numerous trees were snapped, large hardwood trees were uprooted, and several wooden electrical transmission poles were snapped. The peak width of the damage path was measured in this vicinity with widespread damage evident along a mile wide swath. Ground surveys were impeded near Spillman, LA due to widespread tree damage from this tornado, but the damage path and track remained wide and significant as it tracked northeast along Highway 421. High resolution satellite analysis was used to provide the end point for this tornado in which the tornado finally lifted after crossing into rural parts of Wilkinson County in Mississippi. .Bains, LA Tornado... Rating: EF1 Estimated Peak Wind: 100 mph Path Length /statute/: 4.43 miles Path Width /maximum/: 350 yards Fatalities: 0 Injuries: 0 Start Date: 04/10/2024 Start Time: 08:08 AM CDT Start Location: 4 WNW St. Francisville / West Feliciana Parish / LA Start Lat/Lon: 30.8092 / -91.4376 End Date: 04/10/2024 End Time: 08:12 AM CDT End Location: 3 SSW Wakefield / West Feliciana Parish / LA End Lat/Lon: 30.8401 / -91.3737 Survey Summary: High resolution satellite analysis in conjunction with radar imagery and ground survey aided in the confirmation of another tornado that impacted Bains, LA. NDVI difference mapping helped to identify the starting point of this tornado along the bend of Bayou Sara. The tornado then quickly tracked northeast into Bains where it crossed US Highway 61 causing primarily tree damage near an elementary school. Additional damage was not accessible due to Marydale Road being closed, but high resolution satellite imagery did identify a localized swath of tree damage near Alexander Creek tracking just west of the larger tornado that occurred in this area. .Dedeaux, MS Tornado... Rating: EF0 Estimated Peak Wind: 85 mph Path Length /statute/: 5.07 miles Path Width /maximum/: 150 yards Fatalities: 0 Injuries: 0 Start Date: 04/10/2024 Start Time: 10:40 AM CDT Start Location: 8 NNE Diamondhead / Harrison County / MS Start Lat/Lon: 30.5009 / -89.3236 End Date: 04/10/2024 End Time: 10:46 AM CDT End Location: 7 WSW Lyman / Harrison County / MS End Lat/Lon: 30.4816 / -89.244 Survey Summary: As the mesovortex tracked east into Harrison County, another tornado developed on the trailing flank of it and tracked east- southeast over primarily inaccessible rural land near the Wolf River. High resolution satellite imagery NDVI differencing identified a scalloped path that starts near F Malley Road in Dedeaux, MS and continues east-southeast where a ground survey identified snapped trees as well as a mobile home that had slid off its blocks. The tornado crossed River Road with minimal damage evident although the track remained visible on NDVI differencing as it crossed the Wolf River. The apparent track of the tornado continues east across Wolf River Road and appears to conclude just short of Alcede Lizana Road. .Lizana, MS Tornado... Rating: EF1 Estimated Peak Wind: 100 mph Path Length /statute/: 1.48 miles Path Width /maximum/: 100 yards Fatalities: 0 Injuries: 0 Start Date: 04/10/2024 Start Time: 10:44 AM CDT Start Location: 8 W Lyman / Harrison County / MS Start Lat/Lon: 30.5246 / -89.2719 End Date: 04/10/2024 End Time: 10:46 AM CDT End Location: 7 W Lyman / Harrison County / MS End Lat/Lon: 30.511 / -89.2528 Survey Summary: NDVI differencing has helped to identify a tornado damage path that aligned with ground survey of a rolled manufactured home in Harrison County. This brief tornado quickly raced southeast also causing tree damage across Northrup Cuevas Road, just north of a longer-lived tornado that tracked near Wolf River. .Jackson County Tornado... Rating: EF-Unknown Estimated Peak Wind: Unknown Path Length /statute/: 2.22 miles Path Width /maximum/: 75 Yards Fatalities: 0 Injuries: 0 Start Date: 04/10/2024 Start Time: 11:14 AM CDT Start Location: 10 WNW Vancleave / Jackson County / MS Start Lat/Lon: 30.5936 / -88.8283 End Date: 04/10/2024 End Time: 11:16 AM CDT End Location: 8 WNW Vancleave / Jackson County / MS End Lat/Lon: 30.5982 / -88.7913 Survey Summary: An apparent damage path visible on high resolution satellite imagery via NDVI differencing in conjunction with KMOB radar imagery helped to confirm the existence of a weak tornado that tracked through rural parts of the Jackson County on April 10, 2024. No damage indicators could be identified with this analysis and the tornado thus could not be rated. && EF Scale: The Enhanced Fujita Scale classifies tornadoes into the following categories: EF0.....65 to 85 mph EF1.....86 to 110 mph EF2.....111 to 135 mph EF3.....136 to 165 mph EF4.....166 to 200 mph EF5.....>200 mph NOTE: The information in this statement is preliminary and subject to change pending final review of the events and publication in NWS Storm Data. $$
