Cincinnati Ranked First For Tornado-Prone Cities

(CINCINNATI) -- Cincinnati has been ranked the top tornado-prone city in a recent study by VorTek.

VorTek determined the rankings as part of an ongoing company-funded research study of tornadic risk assessment, by means of the Site Assessment of Tornado Threat (SATT) software. Rankings are based on National Weather Service data from 1950 through 2005.

Cincinnati ranked first with an Annual Coverage Fraction (ACF) of 0.038 and 295 acres of disturbed land area.

The ACF represents the average fraction of land area within a 20-mile radius of the city annually disturbed by tornadoes during June for the 56-year period from 1950 through 2005. The "disturbed land area" represents the average number of acres of land within a 20-mile radius of the city annually disturbed by tornadoes during June for the same 56-year period.

Rounding out the top five on the list are Worchester, MA, Des Moines, IA, Minneapolis, MN and Topeka, KS.

The study also found that Ohio is the 11th prone state for tornadoes with a 0.00338 ACF and 886 areas of disturbed land area. Indiana ranked seventh on the list.

Also in the top ten are Nebraska, Wisconsin, Kansas, Iowa, Massachusettes, South Dakota, Illinois, Delaware and Minnesota.
