Significant and intense February tornadoes by state

The graphs above and below examine only those tornadoes either "significant" (F2/EF-2+) or "intense" (F3/E-F3+). All significant tornadoes made up 29.2 percent of the total number of tornadoes in February from 1950-2010.

Significant tornadoes accounted for 97 percent of all February tornado deaths, while intense tornadoes accounted for 87 percent. There were 421 significant tornadoes or 113 intense tornadoes during the period.

Notably, Mississippi leads the pack in F2/EF-2+ and F3/EF-3+ February tornadoes and is tied with Tennessee in the F4/EF-4 category. Florida, while ranked highest for overall February tornadoes ranks 5th on the lesser categories and has seen no F4/EF-4+ in the month. 

Note: If adding up numbers on the graphical representation, you will end up with more tornadoes than there have been because the red zones are tornadoes which crossed a state line after striking another state first.
