Rating: EF2 Estimated Peak Wind: 135 mph Path Length /statute/: 10.22 miles Path Width /maximum/: 880 yards Fatalities: 0 Injuries: 7 Start Date: 05/08/2024 Start Time: 10:54 PM CDT Start Location: 3 SSE Pisgah / Jackson County / AL Start Lat/Lon: 34.6392 / -85.8424 End Date: 05/08/2024 End Time: 11:20 PM CDT End Location: 3 NW Hammondville / DeKalb County / AL End Lat/Lon: 34.6019 / -85.6716 Survey Summary: The tornado touched down between County Road 425 and 322, producing minor damage to the roof of a small farm building. The tornado then overturned a camper and injured two people downstream along County Road 422. Also at this location, a well-built home was partially destroyed. A mobile home was moved off its foundation here as well, with a third of the roof of a hay barn and a horse trailer destroyed. Projectiles were found in the field across the street from this home, with 2x4s impaled a foot to 18" in the ground at this location. Further south and east along State Road 40, large 100+ year old oak trees that were 4-5 foot in diameter were blown down onto a house, collapsing two exterior walls. Windows were sucked out at this location as well prior to the trees falling when the tornado passed just north of the house. Up the street, a well-built home sustained major damage when the tornado ripped the garage off of the house and sheared it to the north and east into the rest of the dwelling. It was at this location that the highest wind speed was rated for this tornado, 135mph, which is the top windspeed for an EF-2 tornado. Had anchor bolts been found in the foundation anchoring of the walls (in lieu of the nails that were found attaching the walls to the foundation), the tornado would have been upgraded to an EF-3 tornado. What was left of the house was in relatively good condition, all things considered, and it was noted that the attic framing was anchored with strongties, and so the roof remained intact over a good portion of the house otherwise. At this point, the tornado was likely at its widest point, measuring half a mile wide. The tornado continued snapping and uprooting softwood trees over the relatively rural landscape along Melton Drive and Elliot Road. It was at this location where the road was impassable due to numerous trees covering the roadway, and it was actively being removed during our survey. Further east/southeast, the tornado moved across the intersection of Culver/Keith/Lacey Roads, snapping and uprooting more softwood trees. The tornado crossed State Road 40, peeling back tin on several chicken houses between SR40 and Valley Road, causing the structural integrity of one of the houses to be compromised. Additional softwood trees were uprooted and snapped near the intersection of County Road 714 and 120 along State Road 40 as well, with the loss of several roof panels to a shed structure at a house located here. The last point of the tornado survey ended with a large oak tree that fell onto a house on CR665 and 670. Further investigation tomorrow may lengthen this tornado track, as additional reports of damage were still being relayed. Impassable roads led to the hastened end to this tornado path this afternoon, but additional information will be investigated tomorrow, May 10th. It is unknown if additional damage indicators will be found that will upgrade this tornado. Additional measurements will be made to solidify the width/length measurement of the tornado as well pending further investigation tomorrow. All information included as of 8pm today is very preliminary and subject to change tomorrow. Ravenscraft/Amin/Dekalb EMA/Jackson EMA Update #1: updated for additional survey results from Madison County .Old Town Tornado... Rating: EF1 Estimated Peak Wind: 105 mph Path Length /statute/: 2.38 miles Path Width /maximum/: 600 yards Fatalities: 0 Injuries: 0 Start Date: 05/08/2024 Start Time: 09:28 PM CDT Start Location: 3 NE Huntsville / Madison County / AL Start Lat/Lon: 34.7377 / -86.5817 End Date: 05/08/2024 End Time: 09:32 PM CDT End Location: 4 ENE Huntsville / Madison County / AL End Lat/Lon: 34.7206 / -86.5468 Survey Summary: An NWS storm survey determined a tornado touched down near Walker Ave NE. The initial touchdown point was indicated by snapping of large branches and significant leaf litter. The tornado continued generally southeast resulting in several large trees uprooted between Walker Ave NE and Randolph Ave SE. This track continued southeast just north of Governors Dr SE with several additional trees both uprooted and snapped. Between Holmes Ave and near Sun Valley Rd SE appears to be the location where the tornado reached its peak intensity of EF1 as indicated by the various uprooted and snapped trees near SE California St and through the Maple Hill Cemetery. Further along this southeast track, the tornado weakened slightly as it tracked north of the Medical District with additional damage of large branches down and leaf litter observed. While our last damage point is just north of Governors Dr SE, radar data indicates the tornadic debris signature continued southeast over Monte Sano. We have requested additional drone and satellite data to further refine the ending of this tornado track and supplement this survey. Some tree damage was noted just south of Governors Dr SE however this was identified as wind damage from inflow winds into the supercell. Thank you to Madison County EMA for their assistance during this survey. Darish/Carmer/Magee .McMullen Cove Tornado ... Rating: EF2 Estimated Peak Wind: 122 mph Path Length /statute/: 0.87 miles Path Width /maximum/: 275 yards Fatalities: 0 Injuries: 0 Start Date: 05/08/2024 Start Time: 09:44 PM CDT Start Location: 4 W Gurley / Madison County / AL Start Lat/Lon: 34.6996 / -86.4389 End Date: 05/08/2024 End Time: 09:48 PM CDT End Location: 3 W Gurley / Madison County / AL End Lat/Lon: 34.7015 / -86.4245 Survey Summary: An NWS storm survey determined that a tornado touched down just north of Little Cove Road. Our initial points for the touchdown were indicated by siding peeled off of a garage and shearing of limbs off of tree tops. The tornado then tracked generally east and continued to distribute leaf litter and snap small branches before beginning to peel some siding on single family homes. The tornado then intensified and caused partial uplift of roofs on the eastern side to four houses on Kenhurst Ln SE. The source of roof failure for these homes came from the eastern portion of the roof. The tornado was able to lift the roof from overhangs facing eastward and then further lift additional portions of the roof. Roof construction appeared primarily via nails and 2x4 with Simpson Strong Ties noted along the base of the roof. Based on these points of strongest intensity, the tornado was deemed a low- end EF2. Roofing material was lofted one block east on Abby Glen Way, where there was also additional scattered shingle damage. No additional damage was noted in this neighborhood. Beyond this neighborhood to the east lies unaccessible rural areas which we could not survey. Additional satellite data has been requested to further analyze the extent of this tornado track and further updates to the end point may be required. Thank you to Madison County EMA for their assistance during this survey. Darish/Carmer/Magee .Brigadoon Tornado... Rating: EF3 Estimated Peak Wind: 136 mph Path Length /statute/: 2.22 miles Path Width /maximum/: 0.13 miles Fatalities: 0 Injuries: 0 Start Date: 05/08/2024 Start Time: 08:23 PM CDT Start Location: 7 SE Rogersville / Limestone County / AL Start Lat/Lon: 34.7499 / -87.1944 End Date: 05/08/2024 End Time: 08:30 PM CDT End Location: 8 N Hillsboro / Limestone County / AL End Lat/Lon: 34.7556 / -87.1561 Survey Summary: A tornado touched down on the Tennessee River just east of where the Elk River meets the Tennessee River and proceeded to move inland at the Brigadoon neighborhood. Public photos and videos confirm the tornado was over water before it moved on land. It first caused damage at Inverness Place and this is where the homes with the largest amount of damage was found. The home that had the greatest damage had all exterior walls facing the river collapsed, the roof of the main part of the house completely gone and the two story four car garage was collapsed with the roof also gone. The front of the house and interior rooms remained in tact. This damage is correlated with low end EF3 damage. Homes nearby had substantial roof damage, damaged vehicles, and other various exterior damage. Numerous large trees throughout the neighborhood were uprooted or snapped. Moving further into the subdivision, there was roof and exterior home damage to a lesser extent, fences knocked over by other debris and broken windows. The tornado lifted in a field outside of the subdivision. Saari/Smith && 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 event and publication in NWS Storm Data. $$
