MOST TORNADO-PRONE SPOT IN ALABAMA

IS IN WALKER COUNTY (REVISED VERSION)

 

 

March 12, 2012        Huntsville, Alabama

 

 

As part of an ongoing tornado research project, by means of the Site Assessment of Tornado Threat (SATT) 3.0 software, and based on National Weather Service data from 1950 through 2010, the Engineering Analysis Inc. (EAI) staff have determined the most tornado prone spot in Alabama, originally identified in March 2003 in Madison County, has moved to a location in Walker County, at latitude 33° 57’ N, longitude 87° 37’ W, which corresponds to a point 85 yards east of State Route 13, 1.9 miles north of Eldridge, Alabama.  During the 61-year period noted, 79 tornado track segments have touched down or passed within 20 miles of this point.  This includes nineteen EF0 tornadoes, twenty-eight EF1, eleven EF2, fifteen EF3, three EF4, and three EF5.  If the total land area disturbed by these tornadoes is divided by the land area within the 20-mile circle, on an annual basis the average fraction of land disturbed (or Annual Coverage Fraction) equals 1.3329 x 10-3 or 0.13329%.  This represents 1072 acres of land which is the largest value for any point within Alabama.
