Nocturnal Tornadoes are two times as deadly compared to tornadoes that occur in the daytime. According to research conducted at Northern Illinois University, Tennessee is considered one of the most vulnerable states because of the high percentage of nocturnal tornadoes in the American South. Using GIS, vulnerable counties in Tennessee will be identified. This will be accomplished by examining the number of nocturnal tornadoes, increase in population from 1980-2010, and number of mobile home parks. GIS mapping techniques will identify the potential vulnerability to these hazards based on the infrastructure in place. Previous research on nocturnal tornadoes has been conducted to the best of the author’s knowledge, but not down to the county level. The current hypothesis is the counties with the most mobile home parks will show the most vulnerability since mobile homes have the highest fatality rate in nocturnal tornadoes.
