Event Summary for Central Alabama
A line of showers and thunderstorm moved through central Alabama during the afternoon and evening hours on April 11. During the early afternoon hours, several discrete supercells moved into central Alabama ahead of the line of storms and produced several areas of damage in west central Alabama. Once the line of storms moved into the area, several segments of the line isolated pockets of damaging winds and downed trees. By late afternoon and early evening several segments along the line of storms began to rotate in a more unstable air mass across southeastern sections of central Alabama. Additional damage occurred along the line as it moved slowly eastward.
The information contained below is the individual tornado events that occurred. The data is PRELIMINARY and may be subject to change.

*The Macedonia/Ethelsville EF-1 Tornado is marked with an asterisk because it was a continuation of the Kemper/Noxubee EF-3 Tornado in Mississippi, surveyed by NWS Jackson, Mississippi. The portion of the tornado in Alabama that was surveyed by NWS Birmingham was rated EF-1.
The tornado damage "swaths" as depicted in the image above, and on the individual tornado links, are an estimate of the damage widths along the track. In other words, the track width may not represent the actual damage in all locations, as we interpolate the values between actual surveyed damage points. These maps are soley for the purpose of showing the general track of each tornado. Remember, tornadoes do not always move in straight lines, and the intensity does not remain constant. It is also possible to have other thunderstorm wind-related damage in close proximity to the tornado tracks from such features as inflow and rear flank downdrafts, which can produce tornado-like damage. |
