Wind, Tornadoes and Flooding on January 30, 2013

Event Summary for Central Alabama

On the morning of January 30th, 2013, a strong storm system moved across the lower Mississippi River and Tennessee River Valleys.  This system not only produced a long-lived squall line or QLCS, but also discrete supercells out ahead of the line.  As the storms crossed into Central Alabama that morning, these thunderstorms caused 5 tornadoes, two areas of significant straight line wind damage and isolated flash and areal flooding.  In addition to the severe weather, widespread reports of downed trees caused by pressure gradient winds were received throughout the day.

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.
