Dixie Alley
Dixie Alley is a nickname sometimes given to areas of the southern United States that are particularly vulnerable to strong or violent tornadoes. This is distinct from the better known Tornado Alley and has a high frequency of strong, long-track tornadoes that move at higher speeds (50+ miles per hour).
== Geography ==
Dixie Alley includes much of the area of the lower Mississippi Valley. It stretches from eastern Texas and Arkansas across Louisiana, Mississippi, Tennessee, Alabama, Georgia, to upstate South Carolina and western North Carolina; the area reaches as far north as southeast Missouri and southwest Kentucky.
Although tornadoes are less frequent in these states than they are in the southern Plains, the southeastern states have had more tornado-related deaths than any of the Plains states (excluding Texas). This is in part due to the relatively high number of strong/violent long tracked tornadoes and higher population density of this region, as well as the Southern United States having the highest percentage of manufactured homes in the US, where 63% of the overall tornado-related fatalities occur. According to the National Climatic Data Center, for the period January 1, 1950 – October 31, 2006, Alabama and Kansas received the largest amount of F5 tornadoes. Complicating matters is that tornadoes are rarely visible in this area, as they are more likely to be rain-wrapped, embedded in shafts of heavy rain, and that the hilly topography and heavily forested landscape makes them difficult to see.〔
