Location: VINEMONT
Tornado F-scale: EF0
Reported by: NWS Storm Survey

A NWS survey team determined the minor damage across portions of northern Cullman County was attributed to an EF-0 tornado with peak winds of 75 MPH.
A strong, bowing line of storms moved quickly through Cullman County during the afternoon of April 30. Within the bowing segment, rotation was detected on radar which tracked through the north central portions of the county.
The damage team found several EF-0 damage indicators in the Vinemont area in the form of uprooted softwood trees and large limb damage. General storm motion from the severe line was northeast. Debris was observed either in a convergent pattern or
oriented in sporadic directions.
The tornado continued north of CR 1422 and CR 1518 toward the Cullman-Morgan Co. line, south of Eva. In this area, the most concentrated area of damage was observed near CR 1526. Amongst several trees uprooted, a metal roof was blown off a large garage/barn and pushed into a single family residence. Additionally, minor roof shingle damage was reported further north on CR 1526. The tornado likely dissipated near CR 1527.
