Event Summary
Remnants of overnight convection across Mississippi reintensified along an outflow boundary and cold pool as it moved into North Alabama during the morning hours of Thursday, May 9th. This activity was fairly benign in nature as it pushed across Northwest Alabama, before rapidly intensifying as it moved into North Central Alabama around 12:00 PM CDT. One section of the line intensified across Madison County, and two strong mesovortices develop. One of these features formed near the Research Park area of Huntsville, causing straight-line wind damage. The second, formed in a rural area in far Northern Madison County near the AL/TN border. The second mesovortex produced a brief EF-0 tornado. As the line pushed east, it continued to develop areas of rotation as it moved into Jackson, Marshall, and DeKalb Counties. Two more EF-1 tornadoes were documented in far east Marshall County (near Kilpatrick) and Dekalb County (Peek’s Corner) from brief, but intense mesovortex features that developed with in the squall line as it moved into the Plateau region of Northeast Alabama. Elsewhere across Northeast Alabama and Southern Middle Tennessee, these thunderstorms produced some additional scattered wind damage and a few instances of small hail.

The tornado progressed toward Old Quick Road, where another large tree was uprooted. It then tracked northeast toward the junction of Jeans Road and Quick School Road, where it started to weaken. Sporadic large limb damage were the main damage indicators in this location. The tornado lifted and dissipated very close to Lincoln Road, in the Mason Branch Creek area.

Est. Peak Winds 95 mph
Path Length 0.57 miles

Summary:

The first evidence of damage was to a barn near the bend in CR 311. The barn was almost entirely collapsed and several nearby trees just east of here were snapped. The most significant damage was to two poultry houses near the corner of CR 311 and CR 50. Half of one poultry house was collapsed and the roofing of the second was peeled away. However, damage to a mobile home across the street was minimal, except for a bulge in the wall in the home. The only other damage spotted was further east along CR 446 where a shed was completely destroyed and the debris spread over a quarter of a mile. No other damage was observed east of this location. We appreciate the assistance from the DeKalb Co EMA.


 

Tornado - Gaines Circle
Marshall County AL

Date May 9, 2019
Time (Local) 1:30 PM CDT
EF Rating EF-1
Est. Peak Winds 95 mph
Path Length 0.48 miles
Max Width 25 yards
Injuries/Deaths 0

Summary:

The first evidence of damage occurred with a snapped tree near a bend at Gaines Circle. The tornado caused minor damage to three barns or sheds. A number of pine trees were snapped near the intersection of Gaines Circle and Gaines Drive. Additional trees were snapped along Gaines Circle before the intersection with Old McVille Road. No further damage was observable east of Old McVille Rd past the Marshall and DeKalb Co line.

The tornado briefly lifted and straight line winds caused damage to the roof of a house and a barn on CR 569. More minor damage occurred to a house and a tree along CR 3. The most significant damage was to a shed behind a house farther east on CR 569 where the roof and walls were uplifted and pushed into the yard. This damage was more sporadic and spread out compared to the damage along Gaines Circle, and therefore is determined to be straight line wind damage. We appreciate the assistance from the Marshall Co and DeKalb Co EMAs.
