The map below is for all the tornado reports across the US in 2015. Many of the Illinois tornadoes occurred in far northern and far southern Illinois this year, while central Illinois has been relatively quiet.
One footnote about tornado reports – it is possible that multiple damage reports may be produced from the same tornado as it moves from one town to the next. Therefore, the number of actual tornadoes may be less than the number of damage reports.
