Due to the complexity of the event and the damage associated with it, additional time was needed to analyze the data. Satellite imagery was also received over the weekend. That, combined with additional ground surveys and radar analysis, led to 8 different tracks being identified between Slidell, LA and east through Kiln, MS. The EF2 track was extended at the start and shifted north at the end. There is additional damage in Harrison and Jackson Counties that requires more analysis. The tornado tracks in West Feliciana, LA are also ongoing additional analysis. More updates will be forthcoming. It`s important to note this data is not final until it is entered and certified into NWS storm data. This means small edits and changes will be likely before final certification. .Alton, LA Tornado... Rating: EF1 Estimated Peak Wind: 90 mph Path Length /statute/: 4.92 miles Path Width /maximum/: 250 yards Fatalities: 0 Injuries: 0 Start Date: 04/10/2024 Start Time: 09:49 AM CDT Start Location: 1 SE Pearl River / St. Tammany Parish / LA Start Lat/Lon: 30.3602 / -89.7344 End Date: 04/10/2024 End Time: 09:58 AM CDT End Location: 2 NNW Slidell / St. Tammany Parish / LA End Lat/Lon: 30.3035 / -89.7831 Survey Summary: A combination of high resolution satellite imagery, ground survey, and radar imagery has aided in the confirmation of a tornado that tracked across Alton and northwest parts of Slidell on the morning of April 10, 2024. This tornado touched down just south of Interstate 12 near Ben Thomas Road and tracked northeast. The tornado crossed Interstate 12 just west of US Highway 11 where the tornado was observed via video confirmation and ground survey of snapped trees. Sporadic tree damage continued northeast with more widespread tree damage being identified around Alton Elementary School. The tornado then crossed US Highway 11 where more tree damage was identified along Highway 1091. Damage became more sporadic and the end point of this tornado is harder to discern due to the beginning of a stronger and larger tornado that crossed nearby this area thereafter. ..Slidell, LA #1... Rating: EF2 Estimated Peak Wind: 120 mph Path Length /statute/: 11.15 miles Path Width /maximum/: 350 yards Fatalities: 0 Injuries: 0 Start Date: 04/10/2024 Start Time: 10:01 AM CDT Start Location: 2 NW Eden Isle / St. Tammany Parish / LA Start Lat/Lon: 30.251 / -89.8143 End Date: 04/10/2024 End Time: 10:12 AM CDT End Location: 5 NW Pearlington / St. Tammany Parish / MS End Lat/Lon: 30.317 / -89.6469 Survey Summary: A 11.3 mile long, 120 MPH, EF2 tornado touched down 1 mile north of Eden Isle and tracked east-northeast causing mainly tree damage through the first half mile or so. It then approached Pontchartrain Drive and caused damage to a few businesses. This damage included a business with all windows blown out, minor roof damage to metal buildings, and snapped power poles. It then continued on through a neighborhood causing mainly tree damage and minor roof damage to homes. It crossed onto Old Spanish Trail where the worst of the damage occurred. A metal business building had failure of roof purlins and metal beams bent. Across the street from this metal business building, two apartment buildings suffered moderate roof damage. The tornado then continued on causing mostly tree damage and minor roof damage to apartments in the Fremaux area. It crossed I-10 and continued to cause additional tree damage before it moved through a few neighborhoods just north and south of US-190, causing damage to a few homes roofs. The damage to these roofs was caused by the failure connection between the walls and the roof. Finally it tracked through the Pearl River Wildlife Management Area before snapping a billboard off of Interstate 10 near the Louisiana- Mississippi border. We received reports of multiple injuries but the total number is unknown. ..Slidell, LA #2 to Stennis... Rating: EF1 Estimated Peak Wind: 90 mph Path Length /statute/: 11.13 miles Path Width /maximum/: 250 yards Fatalities: 0 Injuries: 0 Start Date: 04/10/2024 Start Time: 10:03 AM CDT Start Location: 2 N Slidell / St. Tammany Parish / LA Start Lat/Lon: 30.3083 / -89.7725 End Date: 04/10/2024 End Time: 10:15 AM CDT End Location: 7 NNW Pearlington / Hancock County / MS End Lat/Lon: 30.3604 / -89.6173 Survey Summary: High resolution satellite analysis, ground survey, and radar imagery aided in confirming the existence of another tornado that tracked just south of Interstate 12/10 before crossing the Interstate near Military Road and impacting the neighborhoods along Crawford Landing Road. A localized area of tree damage that aligned along eastbound Exit 83 where branches and trunks were broken or bent east distinctly separates this damage from the damage path to the north and east. This tornado damage is being used as the starting point for the tornado as it aligns with the remainder of the damage path further east. As the tornado tracked east, widespread tree damage was reported across Country Club Blvd with numerous uproots, a few snaps, and many hardwood branches broken. Damage was relatively more sporadic as the tornado crossed near the Interstate interchange until damage became more apparent along Lake Village Blvd and into Crawford Landing Road. Thereafter, the tornado damage path across the Pearl River Wildlife Management Area became increasingly more apparent as the tornado appeared to intensify on high resolution satellite imagery. The tornado damage path was its widest and most intense just west of Perch Lake where the peak width was measured to be near 250 yards. This coincided with the tornado to the south occluding and dissipating which appeared to have given it a boost. After this point, the tornado damage path began to narrow and weaken as the tornado occluded into the tornado to its north. Mostly EF0 damage points were associated with this damage path as the tornado dissipated entering the property of Stennis Space Center. .Stennis #1 Tornado... Rating: EF1 Estimated Peak Wind: 100 mph Path Length /statute/: 19.24 miles Path Width /maximum/: 500 yards Fatalities: 0 Injuries: 0 Start Date: 04/10/2024 Start Time: 10:06 AM CDT Start Location: 1 S Pearl River / St. Tammany Parish / LA Start Lat/Lon: 30.3559 / -89.7519 End Date: 04/10/2024 End Time: 10:31 AM CDT End Location: 1 WNW Kiln / Hancock County / MS End Lat/Lon: 30.4219 / -89.4543 Survey Summary: The beginning of a long-lived tornado developed near Pearl River, LA near the intersection of US Highway 11 and LA Highway 41 where numerous tree branches were snapped and tossed east. A combination of high resolution satellite and radar imagery analysis indicated that this tornado quickly grew in size and intensity after it crossed Interstate 59. Widespread tree damage could be seen on true color satellite imagery growing to a damage path as wide as 500 yards over the Pearl River Basin. Extensive wind damage could be seen extending outward half a mile south of the tornado path as the tornado approached the Louisiana- Mississippi border. The damage path briefly became more obscure and broad as the tornado to its south occluded into Stennis. Extensive tree damage occurred. While ground surveying was limited in and around Stennis Space Center, high resolution satellite imagery identified a swath of damage continued northeastward through Texas Flat Road. Numerous snapped softwood trees and a leaning transmission pole were observed. The damage path gradually became less obvious as the tornado occluded northeast and the end points are associated with tree damage observed west of Kiln along Kiln Picayune Road. ..Stennis #2... Rating: EF0 Estimated Peak Wind: 85 mph Path Length /statute/: 5.33 miles Path Width /maximum/: 300 yards Fatalities: 0 Injuries: 0 Start Date: 04/10/2024 Start Time: 10:17 AM CDT Start Location: 9 ENE Pearl River / Hancock County / LA Start Lat/Lon: 30.3911 / -89.6003 End Date: 04/10/2024 End Time: 10:24 AM CDT End Location: 5 WSW Kiln / Hancock County / MS End Lat/Lon: 30.4033 / -89.5137 Survey Summary: This tornado started fairly large from the start with a swath extending from Leonard Kimble Road and further north along Mainline Road. High resolution satellite imagery indicated the damage path continued eastward where it crossed Texas Flat Road. Branches were broken and a few snapped trees were observed in a generally confluent pattern. The end point for this tornado is estimated based off high resolution satellite NDVI differencing as it interactive with the parent mesovortex and appeared to dissipate. ..Hancock, LA... Rating: EF-Unknown Estimated Peak Wind: Unknown Path Length /statute/: 2.76 miles Path Width /maximum/: 150 yards Fatalities: 0 Injuries: 0 Start Date: 04/10/2024 Start Time: 10:23 AM CDT Start Location: 6 W Kiln / Hancock County / MS Start Lat/Lon: 30.4128 / -89.5306 End Date: 04/10/2024 End Time: 10:27 AM CDT End Location: 3 WSW Kiln / Hancock County / MS End Lat/Lon: 30.4042 / -89.4855 Survey Summary: A short-tracked tornado was identified using high resolution satellite imagery NDVI differencing. This tornado tracked over inaccessible rural lands north of Texas Flat Road along Catahoula Creek and Jourdan River before eventually dissipating as it interacted with the parent mesovortex to its east. No damage could be identified and thus the rating for this tornado is unknown. ..Kiln #1... Rating: EF1 Estimated Peak Wind: 100 mph Path Length /statute/: 3.72 miles Path Width /maximum/: 150 yards Fatalities: 0 Injuries: 0 Start Date: 04/10/2024 Start Time: 10:28 AM CDT Start Location: 2 NW Kiln / Hancock County / MS Start Lat/Lon: 30.4455 / -89.462 End Date: 04/10/2024 End Time: 10:33 AM CDT End Location: 2 ENE Kiln / Hancock County / MS End Lat/Lon: 30.4269 / -89.4043 Survey Summary: Another embedded tornado following along the backside of the mesovortex was identified using high resolution satellite imagery NDVI differencing where more localized damage to trees and structures were identified via ground survey. This tornado tracked primarily along MS Highway 43 with the most widespread damage being located along the curve in Cuevas Road where a swath of trees appeared to be damaged on satellite imagery in addition to observed damage with ground survey. This is where the tornado appeared to be at its strongest. Thereafter, the damage path in NDVI differencing gradually weakens and the tornado is estimated to have dissipated as it crossed the Silver Creek Acres neighborhood where tree damage was found near Violet Street and Gardenia Street in Kiln. ..Kiln #2... Rating: EF0 Estimated Peak Wind: 85 mph Path Length /statute/: 2.79 miles Path Width /maximum/: 150 yards Fatalities: 0 Injuries: 0 Start Date: 04/10/2024 Start Time: 10:31 AM CDT Start Location: 2 NNW Kiln / Hancock County / MS Start Lat/Lon: 30.4511 / -89.4439 End Date: 04/10/2024 End Time: 10:34 AM CDT End Location: 2 NE Kiln / Hancock County / MS End Lat/Lon: 30.4365 / -89.4005 Survey Summary: High resolution satellite imagery aided in identifying yet another embedded tornado that trailed the parent mesovortex that tracked through the area. More localized tree damage in addition to an evident damage path on NDVI differencing helped to confirm the existence of this tornado which tracked from Firetower Road east-southeastward to Old Joe Moran Road. The end point is estimated per satellite imagery which occurred over inaccessible rural lands. && 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. $$
